Addiction as a Chronic Brain Disease
- The modern understanding is that addiction is a chronic, relapsing brain disease, not a moral failing.
- Repeated substance use causes long-lasting changes in the brain's structure and function.
- These changes affect key circuits involved in reward, stress, and self-control.
- This brain-based model is essential for a non-stigmatizing, medical approach to treatment.
- A CPSUD must be a champion of this model.
The Biopsychosocial Model of Addiction
- This model recognizes that addiction is a complex condition influenced by multiple factors.
- Bio (Biological): Genetics, neurobiology, and co-occurring medical conditions.
- Psycho (Psychological): Co-occurring mental illness, trauma history, and coping skills.
- Social: Family, community, and environmental factors (SDoH).
- Effective treatment requires addressing all three domains.
- A CPSUD understands that medication is just one part of a comprehensive treatment plan.
The Pharmacist's Role in SUD Care
- Pharmacists are key members of the SUD treatment team.
- They are medication experts, responsible for dispensing and managing Medications for SUD (MOUD).
- They play a crucial role in harm reduction, especially through naloxone dispensing and syringe services.
- They screen for unhealthy substance use and provide brief interventions.
- They are a key resource for patient education and for connecting patients with treatment.
- A CPSUD has advanced, specialized knowledge to lead these efforts.
Stigma and Person-First Language
- Stigma is a major barrier that prevents people with SUDs from seeking care.
- A CPSUD must be a champion for reducing stigma.
- This involves using person-first, non-stigmatizing language.
- For example, say "a person with a substance use disorder," not "an addict" or "an alcoholic."
- Say "a person who uses drugs," not "a drug user."
- This language shift reflects the understanding of addiction as a medical condition.
The Continuum of Care
- SUD treatment occurs across a continuum of care.
- This ranges from prevention and early intervention to outpatient treatment, intensive outpatient, and residential treatment.
- The ASAM Criteria provide a framework for matching patients to the appropriate level of care.
- A CPSUD must be familiar with this continuum and the different levels of care available in their community.
- They play a key role in facilitating smooth transitions between these levels.
Block 2: Screening, Assessment & Neurobiology
The Reward Pathway
- The mesolimbic dopamine pathway is the key reward pathway in the brain.
- All drugs of abuse cause a large and rapid surge of dopamine in this pathway, particularly in the nucleus accumbens.
- This produces a powerful feeling of pleasure and euphoria.
- The brain remembers this experience and is strongly motivated to repeat it.
- This dopamine surge is much larger and faster than what is seen with natural rewards like food or sex.
Tolerance and Withdrawal
- With repeated use, the brain adapts to the presence of the drug.
- Tolerance: The brain becomes less sensitive to the drug, and a higher dose is needed to achieve the same effect.
- Withdrawal: When the drug is stopped, the brain's adaptations are unopposed, leading to a negative physical and emotional state.
- This withdrawal syndrome is a powerful motivator to continue using the drug to avoid feeling sick.
- Tolerance and physical dependence are normal physiological responses; they are not the same as addiction.
Craving and Relapse
- Long-term use of drugs also causes changes in the brain's learning and memory circuits (e.g., in the hippocampus and amygdala).
- Environmental cues (people, places, things) become strongly associated with drug use.
- When a person is exposed to these cues, it can trigger intense craving.
- These changes in the brain can persist for years after a person stops using.
- This is why addiction is a chronic, relapsing disease.
The Role of the Prefrontal Cortex
- The prefrontal cortex is the part of the brain responsible for executive functions like decision-making, impulse control, and judgment.
- In addiction, the "go" signal from the reward pathway becomes much stronger, and the "stop" signal from the prefrontal cortex becomes weaker.
- This leads to a compulsive, uncontrollable drive to seek and use the drug, despite negative consequences.
- A CPSUD understands this neurobiology to better empathize with and treat their patients.
Genetics and Environment
- Addiction is a complex disease that arises from an interaction between a person's genes and their environment.
- Genetics are thought to account for about half of a person's risk for developing an SUD.
- Environmental factors, such as early life trauma, stress, and social influences, also play a major role.
- A CPSUD understands that addiction is not a choice, but a complex illness.
The SBIRT Model
- SBIRT is an evidence-based, public health approach to delivering early intervention and treatment services for people with or at risk of developing SUDs.
- It is a comprehensive, integrated approach.
- Screening: A universal screening for all patients to assess for risky substance use.
- Brief Intervention: A short conversation with those who screen positive to provide feedback and enhance motivation to change.
- Referral to Treatment: For patients who need more extensive treatment.
- Pharmacists are ideally positioned to perform SBIRT.
Screening Tools for Alcohol
- Single-Question Screen: "How many times in the past year have you had X or more drinks in a day?" (X=5 for men, 4 for women). A response of ≥1 is a positive screen.
- AUDIT-C: A 3-question screening tool that is a component of the full AUDIT. It is scored from 0-12.
- CAGE Questionnaire: A 4-question tool that is easy to remember but less sensitive than the AUDIT-C.
- A CPSUD must be an expert at using these tools.
Screening Tools for Drug Use
- Single-Question Screen: "How many times in the past year have you used an illegal drug or used a prescription medication for non-medical reasons?". A response of ≥1 is a positive screen.
- DAST-10 (Drug Abuse Screening Test): A 10-item, yes/no questionnaire.
- CRAFFT: A screening tool specifically designed for adolescents.
Brief Intervention
- A brief intervention is a short, patient-centered conversation.
- It is not about confronting the patient or telling them what to do.
- It uses the principles of motivational interviewing.
- The goal is to raise the patient's awareness of their substance use and its consequences.
- It helps the patient to explore their own reasons for wanting to make a change.
- It can be as short as 5-10 minutes.
Referral to Treatment
- For patients who have a more severe SUD or who are ready to seek formal treatment, a referral is needed.
- This requires the pharmacist to be knowledgeable about the treatment resources available in their community.
- A "warm handoff," where the pharmacist actively helps the patient to make the first contact with the treatment program, is more effective than a passive referral.
- The SAMHSA treatment locator is a key resource for finding local programs.
The DSM-5 Framework
- The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) is the standard classification of mental disorders used by clinicians.
- It provides a set of diagnostic criteria for each Substance Use Disorder (SUD).
- A pharmacist does not make a formal diagnosis, but they must be familiar with the criteria to understand the condition.
- The DSM-5 combines the previous categories of "substance abuse" and "substance dependence" into a single disorder.
The 11 Criteria
- The diagnosis of an SUD is based on a problematic pattern of use leading to clinically significant impairment or distress, as manifested by at least two of the following 11 criteria, occurring within a 12-month period.
- These criteria are grouped into four categories.
Impaired Control (Criteria 1-4)
- 1. Taking the substance in larger amounts or for longer than you're meant to.
- 2. Wanting to cut down or stop using the substance but not managing to.
- 3. Spending a lot of time getting, using, or recovering from use of the substance.
- 4. Cravings and urges to use the substance.
Social Impairment (Criteria 5-7)
- 5. Not managing to do what you should at work, home, or school because of substance use.
- 6. Continuing to use, even when it causes problems in relationships.
- 7. Giving up important social, occupational, or recreational activities because of substance use.
Risky Use and Pharmacological Criteria (Criteria 8-11)
- 8. Using substances again and again, even when it puts you in danger.
- 9. Continuing to use, even when you know you have a physical or psychological problem that could have been caused or made worse by the substance.
- 10. Tolerance: Needing more of the substance to get the effect you want.
- 11. Withdrawal: Development of withdrawal symptoms, which can be relieved by taking more of the substance.
- The severity of the SUD is based on the number of criteria met: Mild (2-3), Moderate (4-5), or Severe (6 or more).
Block 3: Pharmacotherapy for SUDs
Management of Alcohol Withdrawal
- Alcohol withdrawal can be life-threatening and often requires medical management.
- The goal is to manage the symptoms and prevent the progression to seizures or delirium tremens.
- Benzodiazepines are the first-line treatment. They are a form of cross-tolerant replacement therapy.
- Long-acting BZDs like chlordiazepoxide or diazepam are often preferred.
- In patients with severe liver disease, lorazepam or oxazepam are safer.
- Dosing can be done on a fixed schedule or based on the patient's symptoms using the CIWA-Ar scale.
- Thiamine supplementation is also essential to prevent Wernicke's encephalopathy.
Naltrexone
- Naltrexone is a first-line medication for the treatment of moderate to severe AUD.
- It is an opioid antagonist that is thought to reduce the rewarding effects of alcohol and reduce cravings.
- It is available as a daily oral pill or a monthly long-acting injection (Vivitrol).
- It is contraindicated in patients taking opioids, as it will precipitate withdrawal.
- It can cause hepatotoxicity at high doses, so liver function should be monitored.
Acamprosate
- Acamprosate is another first-line medication for AUD.
- Its mechanism is not fully understood but is thought to restore the balance between GABA and glutamate neurotransmission.
- It is designed to help patients maintain abstinence after they have stopped drinking.
- The dose is two tablets three times a day, which can be a barrier to adherence.
- It is cleared by the kidneys and requires dose adjustment in renal impairment. It is contraindicated in severe renal disease.
Disulfiram
- Disulfiram is a second-line agent.
- It works by blocking the enzyme aldehyde dehydrogenase.
- If a person drinks alcohol while on disulfiram, they will have a severe and unpleasant reaction (flushing, nausea, vomiting, palpitations).
- It is an aversion therapy.
- It is only effective in highly motivated patients who can be supervised.
- It has a risk of hepatotoxicity.
The Pharmacist's Role in AUD Management
- A CPSUD is an expert in the use of all three of these medications.
- They are responsible for counseling patients on the risks and benefits of each option.
- They help to select the best agent based on the patient's goals (harm reduction vs. abstinence) and comorbidities.
- They play a key role in monitoring for adherence and side effects.
- They can work under a CPA to dose and manage these medications.
Management of Opioid Withdrawal
- Opioid withdrawal is intensely unpleasant but not typically life-threatening.
- Symptoms include nausea, vomiting, diarrhea, muscle aches, and anxiety.
- The Clinical Opiate Withdrawal Scale (COWS) is a tool used to assess the severity of withdrawal.
- Withdrawal can be managed with symptom-specific medications (e.g., for nausea) and alpha-2 agonists like clonidine or lofexidine.
- The most effective way to manage withdrawal is to start a medication for OUD like buprenorphine.
Methadone
- Methadone is a long-acting full opioid agonist.
- It is a highly effective medication for OUD.
- Due to its risk of QT prolongation and respiratory depression, its use is restricted to federally-regulated Opioid Treatment Programs (OTPs).
- Patients must go to the OTP daily to receive their dose.
- A CPSUD working in or with an OTP would be an expert in the complex pharmacology and regulations of methadone.
Buprenorphine
- Buprenorphine is a partial opioid agonist.
- This gives it a "ceiling effect" on respiratory depression, making it safer than full agonists like methadone.
- It can be prescribed from an office setting and dispensed by a community pharmacy.
- The requirement for a special "X-waiver" to prescribe it was eliminated in 2023, expanding access.
- It is most often co-formulated with naloxone (Suboxone) to deter injection.
- A key counseling point is that it must be started when the patient is in a state of mild withdrawal to avoid precipitated withdrawal.
Naltrexone
- Naltrexone is an opioid antagonist.
- It works by blocking the effects of opioids.
- It is available as a daily oral pill or a monthly long-acting injection (Vivitrol).
- The patient must be fully detoxed from all opioids for 7-10 days before starting naltrexone to avoid precipitated withdrawal.
- It is a good option for highly motivated patients or for those in situations where any opioid use is prohibited (e.g., certain professions).
The Pharmacist's Role in OUD Management
- A CPSUD is a key leader in expanding access to MOUD.
- They are an expert on the pharmacology and clinical use of all three medications.
- They play a critical role in the induction and monitoring of buprenorphine.
- They are the primary providers of naloxone for overdose prevention.
- In some states, pharmacists can now initiate and manage MOUD under a CPA.
- This is a rapidly expanding area of advanced pharmacy practice.
The Public Health Burden of Tobacco
- Tobacco use is the leading cause of preventable disease, disability, and death in the United States.
- Nicotine is a highly addictive substance.
- A comprehensive public health approach is needed to combat the tobacco epidemic.
- Pharmacists are a key part of this approach.
The 5 A's Model for Counseling
- The 5 A's is an evidence-based framework for brief tobacco cessation counseling.
- Ask: Ask every patient about their tobacco use status.
- Advise: Advise every tobacco user to quit in a clear and personalized manner.
- Assess: Assess the patient's willingness to make a quit attempt.
- Assist: For patients willing to quit, provide counseling and pharmacotherapy.
- Arrange: Arrange for follow-up contact.
- A CPSUD can train other pharmacists on how to effectively use this model.
Nicotine Replacement Therapy (NRT)
- NRT is a first-line pharmacotherapy for cessation.
- It works by reducing the withdrawal symptoms associated with quitting.
- It is available in many OTC and prescription forms (patch, gum, lozenge, inhaler, nasal spray).
- Combination therapy (e.g., the patch plus the gum) is more effective than monotherapy.
- A CPSUD is an expert on the proper use of all forms of NRT.
Non-Nicotine Pharmacotherapy
- There are two main non-nicotine prescription medications.
- Bupropion SR: An antidepressant that also reduces cravings and withdrawal symptoms.
- Varenicline: A partial nicotinic receptor agonist that both reduces cravings and makes smoking less pleasurable. It is the most effective single agent.
- A CPSUD must be an expert on the use, side effects, and contraindications of these medications.
E-Cigarettes and Vaping
- E-cigarettes are a controversial topic in tobacco control.
- While they are likely less harmful than combustible cigarettes, they are not harmless.
- Their long-term health effects are still unknown.
- There is a major public health concern about the epidemic of vaping among young people.
- The FDA has not approved e-cigarettes as a smoking cessation device.
- A CPSUD must be able to provide evidence-based, nuanced counseling on the potential benefits and risks of these products.
Stimulant Use Disorder
- This involves the problematic use of stimulants like cocaine and methamphetamine.
- It is a growing public health problem, often co-occurring with opioid use.
- The intoxication syndrome includes euphoria, agitation, and psychosis.
- The withdrawal syndrome is characterized by severe fatigue, depression, and craving.
- Currently, there are no FDA-approved medications for the treatment of stimulant use disorder.
- The mainstay of treatment is psychosocial therapy, especially contingency management.
Cannabis Use Disorder
- With the increasing legalization of cannabis, rates of cannabis use disorder are also increasing.
- It is characterized by a problematic pattern of use leading to distress or impairment.
- A withdrawal syndrome can occur upon cessation.
- The potency of modern cannabis products is much higher than in the past.
- This increases the risk of both addiction and psychosis.
- The primary treatment is psychosocial therapy (e.g., CBT, motivational interviewing).
- There are no FDA-approved medications for cannabis use disorder.
Benzodiazepine Use Disorder
- This involves the long-term, problematic use of benzodiazepines.
- It is often iatrogenic, starting from a legitimate prescription.
- The primary treatment is a very slow and gradual taper.
- Abrupt cessation can be life-threatening.
- A CPSUD is an expert at designing and managing these complex tapers.
- Psychosocial support is also essential.
Sedative-Hypnotic Use Disorder
- This includes a range of drugs like barbiturates and the "Z-drugs" (e.g., zolpidem).
- Similar to benzodiazepines, these drugs can cause tolerance and a dangerous withdrawal syndrome.
- The management is also similar, involving a slow taper.
- A CPSUD must be able to manage the withdrawal from all types of sedatives.
Gambling Disorder
- Gambling disorder is now included in the DSM-5 as a behavioral addiction.
- It is characterized by persistent and recurrent problematic gambling behavior leading to significant impairment.
- The neurobiology is thought to be similar to that of substance use disorders.
- The primary treatment is psychotherapy (e.g., CBT, Gamblers Anonymous).
- There are no FDA-approved medications, but some have been studied off-label, including naltrexone.
The Prevalence of Co-Occurring Disorders
- The co-occurrence of a substance use disorder and another mental illness is the norm, not the exception.
- Approximately half of all people with a severe mental illness also have a co-occurring SUD.
- This is sometimes referred to as a "dual diagnosis."
- The most common co-occurring conditions are depression, anxiety disorders, and PTSD.
- A CPSUD must be an expert in both addiction and general psychiatry.
Integrated Treatment
- The evidence-based standard of care for co-occurring disorders is integrated treatment.
- This means that both the SUD and the mental illness are treated at the same time, by the same team, in the same location.
- This is much more effective than the older, sequential model where a patient had to get "clean" before their mental illness could be treated.
- A CPSUD is a key member of this integrated treatment team.
SUD and Depression/Anxiety
- There is a strong bidirectional relationship between these conditions.
- People with depression or anxiety may use substances to self-medicate their symptoms.
- Substance use can also cause or worsen depression and anxiety.
- The treatment plan must address both conditions.
- This often involves a combination of MOUD (if applicable), an antidepressant, and psychotherapy.
SUD and PTSD
- The co-occurrence of PTSD and SUD is very common, especially among veterans.
- The treatment must be trauma-informed.
- This involves providing care in a way that is sensitive to the patient's trauma history.
- Trauma-focused psychotherapy is a key part of the treatment.
- Medications for both conditions are also used. Prazosin for nightmares can be particularly helpful.
SUD and Severe Mental Illness (SMI)
- This includes conditions like schizophrenia and bipolar disorder.
- These patients are at a very high risk for SUDs, especially tobacco use disorder.
- The management is very complex and requires a specialized, integrated team.
- Long-acting injectable formulations of antipsychotics can be a key strategy to improve adherence in this population.
- A CPSUD working in a community mental health center would be an expert in managing this complex comorbidity.
Block 4: Specific Pain Conditions & Patient Populations
Diabetic Peripheral Neuropathy (DPN)
- DPN is a common complication of diabetes, causing nerve damage, typically in the feet and legs.
- It often presents with a "stocking-glove" distribution of symptoms.
- Symptoms include burning, tingling, numbness, and shooting pains.
- The cornerstone of management is optimal glycemic control to prevent progression.
- Pharmacotherapy is aimed at symptomatic relief.
- A CPMP plays a key role in managing the complex pharmacotherapy for this condition.
Postherpetic Neuralgia (PHN)
- PHN is a complication of shingles (herpes zoster).
- It is defined as pain that persists for more than 90 days after the onset of the shingles rash.
- The pain is often severe and debilitating, described as burning or stabbing.
- The risk of PHN increases with age.
- The most effective prevention strategy is vaccination against shingles.
- A CPMP is an advocate for and provider of the shingles vaccine.
First-Line Pharmacotherapy for Neuropathic Pain
- The first-line agents for most types of neuropathic pain fall into two main classes.
- Gabapentinoids (gabapentin and pregabalin): Work by modulating calcium channels.
- SNRIs (duloxetine, venlafaxine): Work by enhancing the descending inhibitory pain pathway.
- Tricyclic antidepressants (TCAs) are also a first-line option but are used less frequently in older adults due to side effects.
- The choice between these agents is based on the patient's comorbidities and the side effect profiles.
Second- and Third-Line Agents
- Topical Lidocaine: A first-line option specifically for localized PHN.
- Capsaicin Patch: Can be effective for localized pain but often causes significant application site reactions.
- Tramadol and Tapentadol: Can be considered as second-line agents due to their dual mechanism of action.
- Strong Opioids: Generally considered third-line agents for neuropathic pain due to limited efficacy and significant risks.
- A CPMP must be an expert at sequencing these therapies.
Counseling and Management
- Patient education is critical for managing neuropathic pain.
- It is important to set realistic expectations; complete pain relief is rare.
- The goal is a 30-50% reduction in pain and an improvement in function.
- All of the first-line agents require slow dose titration to minimize side effects.
- A therapeutic trial of a medication may take several weeks at an optimal dose.
- A CPMP is skilled at guiding patients through this titration and trial process.
Pathophysiology (Central Sensitization)
- Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain.
- It is now understood to be a disorder of central pain processing, or "nociplastic" pain.
- The central nervous system becomes amplified and hypersensitive to both painful and non-painful stimuli.
- There is no peripheral tissue damage or inflammation.
- This pathophysiology explains why traditional analgesics like NSAIDs and opioids are ineffective.
Clinical Presentation
- The hallmark symptom is widespread pain, often described as a constant, dull ache.
- It is almost always accompanied by severe fatigue and unrefreshing sleep.
- Cognitive symptoms, often called "fibro fog," are also common.
- Many patients also have co-occurring conditions like depression, anxiety, and irritable bowel syndrome.
- A CPMP must be able to recognize the classic symptom cluster of fibromyalgia.
Non-Pharmacologic Therapy: The Cornerstone
- Non-pharmacologic therapy is the foundation of fibromyalgia management.
- Patient Education: Helping the patient to understand that their pain is real but is due to a sensitized nervous system, not tissue damage.
- Exercise: A graded exercise program, especially low-impact aerobic exercise, is the most effective treatment.
- Cognitive Behavioral Therapy (CBT): Helps patients to change their thoughts and behaviors related to pain.
- Sleep Hygiene: Essential for managing fatigue.
- A CPMP must be a strong advocate for these non-drug approaches.
FDA-Approved Pharmacotherapy
- There are three drugs that are FDA-approved for fibromyalgia.
- All of these agents work on the central nervous system.
- Pregabalin (Lyrica): A gabapentinoid.
- Duloxetine (Cymbalta): An SNRI.
- Milnacipran (Savella): Another SNRI.
- The efficacy of these drugs is modest, providing about a 30% reduction in pain for about half of patients.
- They are considered an adjunct to, not a replacement for, non-pharmacologic therapy.
Inappropriate Therapies
- A key role for the CPMP is to help deprescribe inappropriate medications for fibromyalgia.
- Opioids: Are not effective for fibromyalgia and may even worsen the pain through opioid-induced hyperalgesia. Their use should be strongly discouraged.
- NSAIDs and Acetaminophen: Are generally not effective, as fibromyalgia is not an inflammatory condition.
- Benzodiazepines: Should be avoided due to risks and their negative impact on sleep architecture.
- Educating both patients and providers about these inappropriate therapies is a critical function.
Osteoarthritis (OA)
- OA is a degenerative joint disease, the most common type of arthritis.
- It is characterized by the breakdown of cartilage in the joints.
- It is a leading cause of chronic pain and disability, especially in older adults.
- The pain is nociceptive and often related to activity.
- Non-pharmacologic therapy, including exercise and weight loss, is the cornerstone of management.
Pharmacotherapy for OA
- The choice of medication is guided by a stepwise approach.
- First-line: Topical NSAIDs for knee or hand OA, and oral acetaminophen.
- Second-line: Oral NSAIDs, used at the lowest effective dose for the shortest duration.
- Third-line: Tramadol, duloxetine.
- Intra-articular corticosteroid injections can provide short-term relief.
- Opioids are generally not recommended for chronic OA.
- A CPMP helps to create a safe and effective multimodal regimen.
Acute Low Back Pain (LBP)
- Acute LBP is defined as pain lasting for less than 4 weeks.
- Most cases are non-specific and will resolve on their own.
- The key is to encourage the patient to remain active. Bed rest is not recommended.
- First-line pharmacotherapy is with non-pharmacologic measures and, if needed, NSAIDs.
- Skeletal muscle relaxants may be used for a short course but cause sedation.
- Opioids should be avoided.
Chronic Low Back Pain (LBP)
- Chronic LBP is pain lasting for more than 12 weeks.
- Non-pharmacologic therapies are the foundation of management.
- This includes exercise, physical therapy, and cognitive behavioral therapy.
- First-line pharmacotherapy is NSAIDs.
- Second-line agents include duloxetine and tramadol.
- Opioids are not a preferred therapy for chronic LBP due to a lack of evidence for long-term benefit and significant risks.
- A CPMP is an expert at designing non-opioid regimens for chronic LBP.
Topical Analgesics
- Topical agents are a key part of the multimodal approach for localized musculoskeletal pain.
- They have the major advantage of minimal systemic absorption and fewer side effects.
- Topical NSAIDs (e.g., diclofenac gel): A first-line option for OA of the knee and hand.
- Topical Capsaicin: Can be effective but causes a burning sensation.
- Topical Lidocaine: While approved for PHN, it is often used off-label for musculoskeletal pain.
- A CPMP should be an expert on the evidence and proper use of these agents.
Tension-Type Headache
- This is the most common type of primary headache.
- It is typically described as a bilateral, "band-like" pressure.
- The pain is usually mild to moderate.
- Acute treatment is with simple analgesics like acetaminophen or NSAIDs.
- Frequent use of acute medications can lead to medication-overuse headache.
- For chronic tension-type headache, the first-line preventive treatment is amitriptyline.
Migraine Headache
- A migraine is a disabling primary headache disorder.
- It is typically unilateral, pulsating, and moderate to severe in intensity.
- It is often accompanied by nausea, photophobia, and phonophobia.
- About one-third of patients experience an aura before the headache.
- A CPMP must be an expert in the acute and preventive treatment of migraine.
Acute Migraine Treatment (Abortive Therapy)
- The goal is to treat the attack early to relieve pain and restore function.
- First-line for mild/moderate attacks: NSAIDs.
- First-line for moderate/severe attacks: Triptans (serotonin 1B/1D receptor agonists).
- Newer options: CGRP antagonists ("gepants") and ditans.
- Opioids and butalbital-containing products should be avoided.
- A key counseling point is to avoid overuse of acute medications to prevent medication-overuse headache.
Preventive Migraine Treatment
- Preventive therapy is considered for patients with frequent or disabling migraines.
- Traditional oral options include beta-blockers (e.g., propranolol), antidepressants (e.g., amitriptyline, venlafaxine), and anticonvulsants (e.g., topiramate, valproic acid).
- The choice is guided by the patient's comorbidities and the side effect profile.
- It can take several months to see the full benefit of a preventive medication.
CGRP Antagonists for Prevention
- The newest and most significant advance in migraine prevention is the development of monoclonal antibodies that target Calcitonin Gene-Related Peptide (CGRP).
- These are highly effective and well-tolerated biologic agents.
- They are given as a monthly or quarterly subcutaneous injection.
- There are also oral CGRP antagonists ("gepants") that can be used for prevention.
- These drugs are very expensive and often require a prior authorization.
- A CPMP must be an expert on the use and place in therapy of these new agents.
Geriatric Patients
- Pain is very common in older adults, but its management is complex.
- Older adults are at a much higher risk for adverse drug events due to age-related pharmacokinetic and pharmacodynamic changes.
- The principle of "start low, go slow" is essential.
- NSAIDs should be used with extreme caution due to their renal, GI, and cardiovascular risks.
- Opioids cause more sedation and constipation in older adults.
- A multimodal, non-pharmacologic approach is preferred.
- A CPMP is an expert in safe analgesic prescribing for this population.
Pediatric Patients
- Pain assessment in children, especially pre-verbal infants, is a major challenge.
- Dosing of analgesics in children is almost always weight-based.
- Safe dosing requires careful calculation to avoid errors.
- Codeine should not be used in children due to the risk of ultra-rapid metabolism, which can lead to a morphine overdose.
- A CPMP should be familiar with the principles of pediatric pain management.
Pregnant Patients
- Pain management during pregnancy is a delicate balance between treating the mother's pain and protecting the fetus.
- Acetaminophen is generally considered the safest analgesic during pregnancy.
- NSAIDs should be avoided, especially in the third trimester.
- Opioids should be used cautiously for a short duration. Chronic use can lead to neonatal abstinence syndrome.
- A CPMP can be a key resource for managing pain in this complex population.
Patients with Renal or Hepatic Impairment
- The dosing of many analgesics must be adjusted in patients with kidney or liver disease.
- NSAIDs should generally be avoided in patients with significant renal impairment.
- Acetaminophen is the preferred analgesic for these patients, but the dose must be limited in severe liver disease.
- Many opioids and adjuvant analgesics require dose adjustment for renal dysfunction.
- Morphine has an active metabolite that can accumulate in renal failure. Hydromorphone or fentanyl are often preferred.
Patients with a History of Substance Use Disorder
- Managing pain in patients with a history of or active SUD is a major challenge.
- These patients have a right to effective pain management.
- A multimodal, non-opioid approach should be maximized.
- If opioids are necessary for acute pain, they should be prescribed for a short duration with a clear plan.
- Collaboration with the patient's addiction treatment provider is essential.
- For patients on MOUD (e.g., buprenorphine), special strategies are needed to manage acute pain.
- A CPMP is an expert in navigating these complex clinical and ethical situations.
Block 5: Opioid Stewardship & Risk Management
History of the Opioid Crisis
- The current crisis began in the late 1990s with a dramatic increase in the prescribing of opioid analgesics.
- This was driven by a push to treat pain as the "fifth vital sign" and by aggressive marketing from pharmaceutical companies.
- This first wave led to a rise in addiction and overdose deaths from prescription opioids.
- A second wave began around 2010 with a rise in deaths from heroin.
- The third and current wave, which began around 2013, is driven by illicitly manufactured synthetic opioids, primarily fentanyl.
- A CPMP must understand this history.
The CDC Guideline for Prescribing Opioids for Chronic Pain
- In 2016, the CDC published a landmark guideline to promote safer opioid prescribing.
- It emphasizes that non-opioid therapies are preferred for chronic pain.
- When opioids are used, it recommends starting with the lowest effective dose of an immediate-release formulation.
- It provides specific recommendations on dose thresholds (use caution at >50 MME/day, avoid >90 MME/day).
- It also emphasizes the importance of risk mitigation strategies like PDMP checks and UDT.
- A CPMP is an expert on implementing this guideline.
Opioid Stewardship
- Opioid stewardship is a coordinated set of interventions designed to improve, monitor, and evaluate the use of opioids.
- It is a key strategy for both improving patient safety and combating the opioid crisis.
- The pharmacist is a key leader of the opioid stewardship program in a hospital or health system.
- The program focuses on promoting safe prescribing, monitoring for high-risk use, and providing education.
- A CPMP is often the person who leads these stewardship initiatives.
Harm Reduction
- Harm reduction is a pragmatic public health approach that aims to reduce the negative consequences of substance use.
- It is a key part of a comprehensive response to the overdose crisis.
- Key harm reduction services include:
- Naloxone Access: Dispensing the opioid overdose reversal drug.
- Syringe Service Programs (SSPs): Providing sterile syringes to prevent the spread of HIV and Hepatitis C.
- Fentanyl Test Strips: Allowing people to test their drugs for the presence of deadly fentanyl.
- A CPMP should be a strong advocate for these life-saving services.
Medication-Assisted Treatment (MAT) / MOUD
- The evidence-based standard of care for Opioid Use Disorder (OUD) is Medications for OUD (MOUD), formerly known as MAT.
- The three FDA-approved medications are methadone, buprenorphine, and naltrexone.
- A key public health goal is to expand access to MOUD.
- Pharmacists are playing an increasingly important role in this, including initiating buprenorphine in some states.
- A CPMP is an expert on the pharmacology and clinical use of these medications.
Universal Precautions for Opioids
- The concept of "universal precautions" for opioids is an approach that applies a standard set of risk mitigation strategies to all patients on chronic opioid therapy.
- This is because it is difficult to predict which individual patient will develop a problem.
- This approach moves away from just trying to identify "problem patients."
- The core components are a thorough assessment, a treatment agreement, regular monitoring, and documentation.
Risk Assessment Tools
- Validated screening tools can be used to assess a patient's risk for opioid misuse or addiction before starting therapy.
- The Opioid Risk Tool (ORT) is a brief, self-report screening tool for use in primary care.
- The Screener and Opioid Assessment for Patients with Pain (SOAPP) is another commonly used tool.
- These tools can help to stratify patients by risk (low, moderate, high) and to guide the intensity of the monitoring strategy.
Prescription Drug Monitoring Programs (PDMPs)
- PDMPs are state-level databases that track the dispensing of controlled substances.
- They are a critical tool for identifying patients who may be receiving prescriptions from multiple providers ("doctor shopping") or filling at multiple pharmacies.
- Most states now mandate that prescribers and/or pharmacists check the PDMP before prescribing or dispensing an opioid.
- A CPMP must be an expert user of their state's PDMP.
Urine Drug Testing (UDT)
- UDT is another key tool for monitoring patients on chronic opioid therapy.
- It is used to verify that the patient is taking their prescribed opioid (an expected positive result).
- It is also used to screen for the use of non-prescribed or illicit drugs (an unexpected positive result).
- The results of a UDT must be interpreted carefully.
- A CPMP must understand the limitations of the test and the metabolic pathways of different opioids to avoid misinterpretation.
Patient-Provider Agreements (Pain Contracts)
- A patient-provider agreement is a formal document that outlines the expectations and responsibilities of both the patient and the provider.
- It is a tool for promoting communication and informed consent.
- It typically includes the goals of therapy, the plan for monitoring, and the policies on issues like early refills and lost prescriptions.
- The agreement should be used to facilitate a conversation, not just as a contract to be signed.
- A CPMP can help to develop and implement these agreements.
Rationale for Tapering
- Opioid tapering is the process of gradually reducing a patient's long-term opioid dose.
- It should be considered for any patient on chronic opioid therapy who is not having a clinically meaningful improvement in pain and function.
- It is also indicated for patients who are on high doses (>50 MME/day) or who are experiencing adverse effects.
- The goal is to reduce the risks of long-term opioid therapy while minimizing withdrawal symptoms.
- A CPMP is an expert in managing this complex and challenging process.
The Shared Decision-Making Conversation
- The decision to taper must be made in collaboration with the patient.
- Many patients are very fearful of a dose reduction.
- The conversation must be empathetic and non-judgmental.
- It should focus on the shared goal of improving the patient's safety and quality of life, not on simply reducing a number.
- The pharmacist can use motivational interviewing techniques to help the patient explore their own reasons for wanting to taper.
Developing a Tapering Plan
- The tapering plan must be individualized.
- There is no one-size-fits-all approach.
- A general rule of thumb is to reduce the total daily dose by about 10% every 1-4 weeks.
- The taper should be slower for patients who have been on opioids for a long time or who are very anxious.
- The plan must be clear and provided to the patient in writing.
- A CPMP is an expert at creating these patient-specific tapering schedules.
Managing Withdrawal Symptoms
- A slow taper is designed to minimize withdrawal symptoms, but some may still occur.
- Common symptoms include anxiety, insomnia, nausea, and muscle aches.
- Adjunctive medications can be used to help manage these symptoms.
- Clonidine is often used to treat the autonomic symptoms of withdrawal.
- Other comfort medications can be used for nausea, diarrhea, and insomnia.
- The CPMP can recommend and manage these adjunctive medications.
Monitoring and Support
- Close follow-up and support are essential for a successful taper.
- This involves regular check-ins with the patient, either in person or by phone.
- The pharmacist should monitor for withdrawal symptoms and assess the patient's pain and function.
- It is important to provide positive reinforcement and to celebrate small successes.
- The plan may need to be adjusted based on the patient's response. The patient should be empowered to have control over the pace of the taper.
Defining OUD
- OUD is a chronic, relapsing brain disease characterized by a problematic pattern of opioid use leading to clinically significant impairment or distress.
- It is a medical diagnosis, defined by criteria in the DSM-5.
- It is not a moral failing.
- A key part of the CPMP's role is to reduce the stigma associated with OUD.
- This includes using person-first, non-stigmatizing language.
Screening and Diagnosis
- The pharmacist can play a key role in screening for OUD.
- This involves being alert to "red flags" in the pharmacy, such as patients frequently requesting early refills or appearing sedated.
- Validated screening tools can also be used.
- A formal diagnosis is made by a qualified provider based on the 11 criteria in the DSM-5.
- The pharmacist's role is to screen and refer for diagnosis.
Medications for OUD (MOUD)
- MOUD is the evidence-based standard of care for OUD. It significantly reduces the risk of overdose death.
- Methadone: A long-acting full opioid agonist. Can only be dispensed by a federally-regulated Opioid Treatment Program (OTP).
- Buprenorphine: A partial opioid agonist. Can be prescribed from an office setting and dispensed by a community pharmacy.
- Naltrexone: An opioid antagonist. Available as a long-acting injection (Vivitrol). The patient must be fully detoxed from opioids before starting.
- A CPMP is an expert on these life-saving medications.
The Pharmacist's Role in Buprenorphine Therapy
- Pharmacists are a key partner in expanding access to buprenorphine.
- They are responsible for dispensing the medication and providing patient education.
- They play a crucial role in the induction process, ensuring the patient is in a state of mild withdrawal before the first dose to prevent precipitated withdrawal.
- They help to monitor for adherence and side effects.
- In some states, pharmacists now have the authority to initiate buprenorphine therapy under a CPA.
Harm Reduction
- Harm reduction is a pragmatic approach that aims to reduce the negative consequences of substance use.
- It is a key part of a comprehensive approach to OUD.
- Key harm reduction services that can be provided by a pharmacy include:
- Naloxone Access: Dispensing the opioid overdose reversal drug.
- Syringe Service Programs (SSPs): Providing sterile syringes to prevent the spread of HIV and Hepatitis C.
- Fentanyl Test Strips: Allowing people to test their drugs for the presence of deadly fentanyl.
- A CPMP is a strong advocate for removing barriers to these services.
The Importance of Non-Drug Therapies
- For chronic pain, non-pharmacologic therapies are the foundation of management.
- They are often more effective than medications in the long term and have fewer side effects.
- A multimodal approach that combines these therapies with medication is the standard of care.
- A CPMP must be an expert on these non-drug approaches and be able to refer patients to the appropriate providers.
- They are a key part of a holistic, biopsychosocial treatment plan.
Physical and Rehabilitative Therapies
- Physical Therapy (PT): A cornerstone of chronic pain management. It focuses on improving movement and function through a tailored exercise program.
- Occupational Therapy (OT): Helps patients to perform their activities of daily living.
- Massage Therapy: Can be helpful for musculoskeletal pain.
- Acupuncture: Has evidence for several types of chronic pain, including low back pain and migraine.
- TENS (Transcutaneous Electrical Nerve Stimulation): Uses low-voltage electrical current to provide pain relief.
Psychological and Behavioral Therapies
- These therapies are essential for addressing the "psycho" part of the biopsychosocial model.
- Cognitive Behavioral Therapy (CBT): The most well-established psychological therapy for chronic pain. It helps patients to change their thoughts, emotions, and behaviors related to pain.
- Acceptance and Commitment Therapy (ACT): A mindfulness-based therapy that helps patients to live a meaningful life despite their pain.
- Biofeedback: A technique that teaches patients to control physiological functions like muscle tension.
Mind-Body Practices
- These practices focus on the interaction between the brain, mind, body, and behavior.
- Yoga and Tai Chi: Combine gentle movement, breathing, and meditation. Have good evidence for conditions like low back pain.
- Mindfulness-Based Stress Reduction (MBSR): A formal program that teaches mindfulness meditation.
- These practices can help to down-regulate the sensitized nervous system in chronic pain.
The Pharmacist's Role in Promoting Non-Drug Therapies
- The CPMP is a key advocate for and educator about these non-drug approaches.
- They can provide basic counseling on things like the importance of exercise and sleep hygiene.
- They can also make formal referrals to other providers on the interdisciplinary team, such as physical therapists and psychologists.
- This integrated approach is the key to successful chronic pain management.
- It helps to move beyond a purely medication-focused model of care.
Block 6: Program Management & Evaluation
Needs Assessment
- The first step in developing any program is to conduct a thorough needs assessment.
- This involves using data to identify the key health problems in a community.
- The Community Health Needs Assessment (CHNA) is a formal process for this.
- The assessment should also identify the community's assets and resources.
- A CPHP uses their analytical skills to contribute to this data-driven process.
Logic Models
- A logic model is a visual tool that shows the relationship between a program's resources, activities, and expected outcomes.
- It is a roadmap for the program.
- Inputs: The resources needed (e.g., staff, funding).
- Activities: What the program will do (e.g., provide screenings).
- Outputs: The direct products of the activities (e.g., number of screenings performed).
- Outcomes: The changes that result from the program (short-term, intermediate, and long-term).
- A CPHP should be able to develop a logic model for a pharmacy-based public health program.
Setting SMART Objectives
- The program's goals and objectives must be clearly defined.
- The SMART framework is used to create effective objectives.
- Specific: What exactly will you do?
- Measurable: How will you know if you have met the objective?
- Achievable: Is the objective realistic?
- Relevant: Does the objective align with the overall goal?
- Time-bound: When will the objective be achieved?
Engaging Stakeholders
- A successful program must have the buy-in of key stakeholders.
- This includes community members, other healthcare providers, and potential funders.
- Engaging stakeholders in the planning process is essential.
- This ensures that the program is relevant to the community's needs and is culturally appropriate.
- A CPHP is a skilled collaborator and relationship-builder.
Securing Funding
- Public health programs are often funded through grants.
- A CPHP may be involved in writing grant proposals.
- This requires the ability to articulate the public health need, the proposed intervention, and the plan for evaluation.
- A strong business case and a clear budget are essential.
- This is a key skill for a public health leader.
Project Management
- Implementing a new program is a complex project.
- A CPHP must have strong project management skills.
- This involves creating a detailed work plan with a clear timeline.
- It requires managing a budget and a project team.
- Tools like a Gantt chart can be used to track progress.
Marketing and Recruitment
- Once a program is launched, participants must be recruited.
- This requires a formal marketing and outreach plan.
- The marketing materials must be culturally and linguistically appropriate for the target audience.
- Working with community partners is a key strategy for recruitment.
- A CPHP must be able to "sell" their program to the community.
Staffing and Training
- The CPHP is often responsible for hiring and training the staff for the new program.
- This includes developing clear job descriptions and providing a comprehensive orientation.
- Ongoing training and competency assessment are also essential.
- This ensures that the program is delivered with high fidelity.
Quality Assurance
- A formal Quality Assurance (QA) program is needed to monitor the implementation of the program.
- This involves regularly reviewing the program's activities to ensure they are being delivered as intended.
- This is the focus of a process evaluation.
- The QA program provides real-time feedback that can be used to make course corrections.
Budget Management
- The CPHP is responsible for managing the program's budget.
- This involves tracking all expenses and ensuring that the program is staying within its budget.
- They must be able to provide regular financial reports to the program's funders.
- This financial acumen is a key management skill.
The Purpose of Program Evaluation
- Program evaluation is the systematic collection of information about a program to assess its effectiveness and make decisions.
- It is the final stage of the policy cycle and a key part of the 10 Essential Services.
- It answers the question: "Did the program work?"
- The findings from an evaluation are used to improve, continue, or terminate a program.
- A CPHP must be able to design and interpret program evaluations.
Types of Evaluation
- Process Evaluation: Assesses how a program is being implemented. Is it reaching the target population? Are the activities being delivered as planned?
- Outcome/Impact Evaluation: Assesses the extent to which a program has achieved its intended outcomes. Did the program actually improve health?
- Economic Evaluation: Assesses the cost-effectiveness of the program. Were the benefits worth the costs?
- A comprehensive evaluation often includes all three types.
Evaluation Design
- The "gold standard" for an impact evaluation is the Randomized Controlled Trial (RCT).
- However, RCTs are often not feasible in a real-world public health setting.
- Therefore, quasi-experimental designs are often used.
- This involves using a comparison group that is similar to the intervention group but did not receive the program.
- A CPHP should be familiar with these common evaluation designs.
Data Collection and Analysis
- The evaluation plan must specify what data will be collected and how.
- This can include both quantitative data (e.g., from surveys or health records) and qualitative data (e.g., from focus groups or interviews).
- The CPHP is responsible for the analysis of this data.
- This requires skills in biostatistics and data management.
Communicating Findings
- The final step of the evaluation is to communicate the findings to stakeholders.
- This is typically done in a formal evaluation report.
- The report should be clear, concise, and objective.
- It should include a set of actionable recommendations based on the findings.
- The CPHP must be skilled at translating complex evaluation results into a format that is useful for decision-makers.
Behavioral Risk Factor Surveillance System (BRFSS)
- The BRFSS is a state-based system of health surveys that collects data about U.S. residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services.
- It is a key source of data for Community Health Needs Assessments (CHNAs).
- A CPHP uses this data to understand the prevalence of key risk factors (e.g., smoking, obesity) in their state or local community.
- This data is essential for program planning and priority setting.
Youth Risk Behavior Survey (YRBS)
- The YRBS is a CDC-led national survey that monitors health behaviors that contribute to the leading causes of death and disability among youth and young adults.
- It provides key data on issues like substance use, sexual behaviors, and mental health in adolescents.
- A CPHP would use this data to inform prevention programs for young people.
- This tool is critical for understanding the health needs of the adolescent population.
Health-Related Quality of Life (HRQOL) Scales
- Standardized, validated questionnaires used to measure a person's perception of their own health.
- A common example is the SF-36 or SF-12, which measure various domains of physical and mental health.
- These tools are used in program evaluation to measure the impact of an intervention on a patient's quality of life.
- This is a key patient-centered outcome.
- A CPHP uses these scales to demonstrate the holistic value of public health programs.
Health Literacy Assessment Tools
- Tools used to assess an individual's or a population's health literacy.
- REALM (Rapid Estimate of Adult Literacy in Medicine): A word recognition test.
- TOFHLA (Test of Functional Health Literacy in Adults): A reading comprehension test.
- Newest Vital Sign: A quick test that uses a nutrition label to assess both literacy and numeracy.
- These tools are used in research and can be adapted for clinical screening to identify patients who may need extra support.
Community Health Needs Assessment (CHNA) Tools

- The CDC and the Catholic Health Association are key sources for these tools.
- They provide guidance on how to collect and analyze quantitative and qualitative data.
- They also provide frameworks for engaging community stakeholders and prioritizing health needs.
- A CPHP participating in a CHNA would use these standardized tools to ensure a rigorous and valid assessment.
Prevalence
- A fundamental measure of disease frequency. It represents the proportion of a population that has a disease at a specific point in time. It's a snapshot of the disease burden.
\( \text{Prevalence} = \frac{\text{Number of Existing Cases}}{\text{Total Population}} \)
Incidence Rate
- Another fundamental measure of disease frequency. It measures the rate at which new cases of a disease develop in a population over a period of time. It is a measure of risk.
\( \text{Incidence Rate} = \frac{\text{Number of New Cases}}{\text{Person-Time at Risk}} \)
Relative Risk (RR)
- A key measure of association from a cohort study. It compares the incidence of disease in an exposed group to the incidence in an unexposed group.
\( \text{RR} = \frac{\text{Incidence in the Exposed}}{\text{Incidence in the Unexposed}} \)
Odds Ratio (OR)
- A key measure of association from a case-control study. It compares the odds of exposure in the cases to the odds of exposure in the controls. For rare diseases, the OR approximates the RR.
\( \text{OR} = \frac{\text{Odds of Exposure in Cases}}{\text{Odds of Exposure in Controls}} = \frac{ad}{bc} \)
Sensitivity and Specificity
- These are measures of the validity of a screening test. Sensitivity is the ability of a test to correctly identify those with the disease. Specificity is the ability to correctly identify those without the disease.
\( \text{Sensitivity} = \frac{\text{True Positives}}{\text{All Diseased}} \) ; \( \text{Specificity} = \frac{\text{True Negatives}}{\text{All Non-Diseased}} \)

- They are the ones who can turn the raw data into the actionable intelligence that is needed to drive public health improvement.
- This is a highly specialized and in-demand skill set at the intersection of pharmacy, public health, and data science.
Prevention is the Primary Goal
- The core focus of public health is to prevent disease before it happens.
- This requires an "upstream" approach that addresses the root causes of poor health.
- While treatment is important, a public health perspective always prioritizes primary prevention.
- A CPHP is a leader in preventive health, from immunizations to smoking cessation.
Focus on Populations, Not Just Individuals
- While all healthcare is delivered to individuals, public health thinks in terms of populations.
- The goal is to improve the health of the entire community, not just the patients who walk through the door.
- This requires a different set of skills, including epidemiology and data analysis.
- A CPHP must be able to move between the individual patient level and the broader population health level.
Health Equity is a Core Value
- Public health has a fundamental commitment to social justice.
- A core goal is to eliminate health disparities and achieve health equity.
- This requires a focus on the Social Determinants of Health and the needs of the most vulnerable populations.
- A CPHP must be a champion for health equity in all of their work.
Evidence is the Foundation
