    ABCDE’S OF ADDICTION

    Addiction is characterized by:• Inability to consistently Abstain;• Impairment in Behavioral control;• Craving; or increased “hunger” for drugs

    or rewarding experiences;• Diminished recognition of significant

    problems with one’s behaviors and interpersonal relationships; and

    • A dysfunctional Emotional response.

    WHY TREAT ADDICTION WITH MEDICATIONS?

    • Treat overdose• Facilitate abstinence

    – Medically supervised withdrawal– Restore balance to brain systems– Treat co-occurring conditions

    • Prevent relapse– Stress reduction– Cues/craving– Block action of drugs– Cognitive enhancement/decision-making

    GOALS AND RATIONALE FOR SPECIFICPHARMACOTHERAPY FOR AN ADDICTION

    1.Prevent withdrawal symptoms2.Reduce drug craving3.Normalize any physiological functions

    disrupted by drug use4.Target treatment agent to specific site of

    action, receptor, or physiological system affected or deranged by drug of abuse

    IDEAL PHARMACOTHERAPY FOR TREATMENT OF ADDICTION

    • Orally effective

    • Onset of action

    – Slow onset for maintenance therapy

    – Rapid onset for withdrawal treatment

    • Long duration of action

    • Slow offset of action

    • [Not psychoactive?]

    Cocaine: Onset of Effects, Peak Effects, Duration of Euphoria, and Plasma Half-Life by Routes of Administration• Rates of rise of blood (and presumably brain) levels of drugs of

    abuse are related positively to their reinforcing effects• Rates of fall of blood (and presumably brain) levels of drugs of

    abuse are related positively to the onset of withdrawal symptoms and/or acute “craving”

    HOW MIGHT MEDICATION ASSISTED TREATMENTS WORK?

    • Occupy same brain receptors as drugs– Methadone, Buprenorphine

    • Decrease craving– Naltrexone, Acamprosate, Bupropion, Buprenorphine, etc.– Topiramate and others?

    • Block effects of drugs– Naltrexone, Naloxone, Buprenorphine

    • Cause aversive reactions– Antabuse (Disulfiram)

    • Reverse drug effects – Amethystic agents [Holy Grail of addiction treatment?]:

    mythical treatment capable of counteracting the acute effects of alcohol on the CNS, hastening sobriety

    • Help the brain heal?

    ALCOHOL

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    ALCOHOL INTERACTS WITH MULTIPLE CNS NEUROTRANSMITTER SYSTEMS

    • Glutamate• GABA• Dopamine• Serotonin • Endogenous opioids

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    ALCOHOL: GABA AND GLUTAMATE• Alcohol use temporarily disrupts the balance between neuronal

    excitation and inhibition• GABA system:

    – Primary CNS inhibitory neurotransmitter– Alcohol and other sedatives activate GABA-A and acutely

    decrease cell excitability • Glutamate system:

    – Primary excitatory system in CNS– NMDA (N-methyl-D-aspartate) receptors bind glutamate– Chronic alcohol exposure leads to: Upregulation/increasing

    number of NMDA receptors --> Contributes to development of tolerance

    • Upon stopping alcohol use:– Excessive glutamate-induced excitation– Hyperexcitatory state (hallucinations, hyperactivity, seizures)– Increases risk of excitotoxic cell death– Leads to cognitive deficits?

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    ALCOHOL: ENDOGENOUS OPIOID SYSTEM

    • Alcohol intake is associated with increasedrelease of endogenous opioids (Beta-endorphins)– Mediates euphoric effect of alcohol

    • Endogenous opioids stimulate increased release of dopamine in the Nucleus Accumbens

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    MEDICATIONS FOR ALCOHOL USE DISORDERS, MECHANISMS OF ACTION• FDA-Approved

    – Disulfiram (Antabuse®)= aversive contingency, not neuromodulatory for alcohol craving

    – Acamprosate (Campral®)=glutamate system– Naltrexone (ReVia®, Vivitrol®)=endogenous

    opioid system, indirectly dopamine

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    DISULFIRAM• Dose125-500 mg per day (usually 250 mg)• Effects can last up to 2 weeks after last dose• Not a neuromodulator, only aversive contingency• Effects depend on compliance; observed dosing best• Disulfiram-alcohol reaction:

    – Flushing, throbbing in head and neck, throbbing headache– Respiratory difficulty – Nausea, copious vomiting, sweating, thirst– Chest pain, palpitation– Dyspnea, hyperventilation– Tachycardia, hypotension, syncope– Marked uneasiness, weakness, vertigo, blurred vision– Confusion – In severe reactions, there may be respiratory depression, cardiovascular

    collapse, arrhythmias, myocardial infarction, acute congestive heart failure, unconsciousness, convulsions, and death.

    NALTREXONE• Mu Opioid antagonist• Not scheduled, not addicting• Available formulations:

    – Oral 50 mg tablets (ReVia®, Depade®, others): take 50 mg qday, or 100 mg q48 hours, or 150 mg q72 hours

    – 380 mg depot injectable formulation (Vivitrol®) every 28-30 days

    • Same technology as Risperidone Consta• Expensive (cash price $1700 per injection)

    • FDA-Approved for treatment of:– Opioid dependence (tablets 1984, depot form 2006):

    Long-term opioid blockade in recovering persons– Alcohol Dependence (tablets 1994, depot form 2010):

    Treatment of alcohol craving, prevention of relapse

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    HOW MIGHT NALTREXONE/OPIOID ANTAGONISTS WORK FOR ALCOHOL USE DISORDERS?

    • Block pleasurable reinforcing effects of alcohol– Opioid Antagonists block alcohol-induced

    Dopamine (DA) release in Nucleus Accumbens• Alleviate craving for alcohol• Increase aversive effects of alcohol

    – Nausea, vomiting (not as severe as disulfiram)• Alter neuroendocrine responses to alcohol

    – Alcohol activates HPA axis– Alcohol triggers release of ACTH, Beta-endorphins,

    glucocorticoids (mediates some of positive effects)

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    NALTREXONE• Alcohol Use Disorders

    – Decreases alcohol craving, rate of relapse, positive reinforcement and length of drinking episodes

    – All studies combined medication with psychosocial supports

    • Opioid Use Disorders– Long-term opioid blockade in recovering persons– Naltrexone binds tightly to opioid receptor– No drug effect if opioids used while on naltrexone

    therapy– Depot naltrexone decreases opioid craving

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    ACAMPROSATE• (Calcium acetylhomotaurinate)• Chemical structure similar to that of

    homotaurine and GABA (naturally occurring amino acid mediators)

    • Has neuroprotective and abstinence-promoting effects – Attenuates glutamate release in alcohol withdrawal– Blocks excitotoxicity produced by alcohol– Modulates cue-elicited drinking behaviors

    • Reduces alcohol relapse, increases treatment retention, promotes abstinence from alcohol, reduces protracted abstinence

    • Available in France since 1989, US since 2005

    METHADONE DANGERS

    • Overdose Risk – Black Box Warning and FDA Health Advisory, 2006

    • “Methadone’s peak respiratory depression effects typically occur later, and persist longer, than its peak analgesic effects…” “Patients tolerant to other opioids may be incompletely tolerant to methadone….”

    • Pain relief from methadone lasts 4 to 8 hours.• Methadone elimination half-life variable, 8 to 59 hours

    • Cardiac Toxicity– Potent inhibitor of hERG potassium channels,

    involved in cardiac repolarization– Bradycardia– May cause prolonged QTcàTorsades de Pointes

  • © U N I V E R S I T Y O F U T A H H E A L T H , 2 0 1 7

    METHADONE OVERDOSE RISK• Steady-state methadone

    concentration reached in about 5 days (5xT1/2) – [range 45 hrs to 12+ days]

    • Danger of overdose: – Initial dose too high or– Dose escalation too rapid or– Concomitant use of CYP 450

    inhibitors• MMT initial doses capped at 30

    mg/day and dose escalation gradual

    • Pain treatment and street use comprise most methadone OD’s

    PRESCRIBING OF BUPRENORPHINE IN U.S.• Drug Abuse Treatment Act (DATA 2000):

    – Opioid detoxification and primary addiction treatment in the office-based setting allowed with Schedules III, IV or V agents approved for addiction treatment

    – Physicians must qualify and register for a special DEA number if using buprenorphine-naloxone or buprenorphine for addiction treatment (XA#######)

    – ONLY physicians can prescribe for addiction treatment; 30 patient limit per physician for one year after waiver, then can apply to increase patient limit to 100-275 depending on qualifications

    • Approval of sublingual buprenorphine for the treatment of opioid addiction is significant– First time (since a U.S. Supreme Court ruling in 1918) that

    physicians have been allowed to manage opioid addiction in the office-based setting

    – Shift to medical management model

    GABAPENTIN FOR CANNABIS USE, WITHDRAWAL, EXECUTIVE FUNCTION

    • Pre-clinical findings:– gabapentin normalizes the CRF-induced GABA activation in the

    amygdala. Calcium-channel-GABAergic mechanism of action has relevance for restoring homeostasis in brain stress (CRF) systems

    – cannabis withdrawal produces anxiogenic-like state and increased extrahypothalamic CRF release in the central nucleus of the amygdala in rodents.

    – GABA–CRF interactions and their role in the motivational aspects of cannabis relapse provide pre-clinical rationale in healthy volunteers.

    • Clinical studies:– gabapentin reduces craving and disturbances in sleep and mood

    • the most persistent symptoms of protracted cannabis withdrawal• a key reason patients resume smoking marijuana.

    – Gabapentin showed subtle cognitive-enhancing effects in the domains of attention, concentration, visual–motor functioning, inhibition, and set shifting in healthy volunteers.

    PROPORTION OF NEGATIVE URINE CANNABINOID TESTS OVER TIME AMONG CANNABIS-DEPENDENT ADOLESCENTS IN A RANDOMIZED CONTROLLED TRIAL OF N-ACETYLCYSTEINE (NAC) 1200 MG BID

    a In this intent-to-treat analysis, all randomized participants (N=116) were included, and urine cannabinoid tests were assumed to be positive for all missed visits. With adjustment for years of cannabis use, baseline urine cannabinoid test results, and major depressive disorder, odds ratio=2.4, 95% CI=1.1–5.2; χ2=4.72, p=0.029.

    CROSS-ADDICTION: GENERAL PRINCIPLES

    • AVOID the use of any psychoactive substances in persons with a history of alcohol/drug use disorders

    • Use of any psychoactive substance may lead to:– Addiction to or craving for

    that substance– Craving for or relapse

    CROSS-ADDICTION: GENERAL PRINCIPLES • Physicians and other prescribers are woefully

    ignorant about, or choose to ignore, the risks for cross-addiction and iatrogenic relapse

    • Relapse can result even when there is a legitimate medical or psychiatric rationale for medication use

    • Examples • Exceptions?

    – Methadone, Suboxone, or Subutex for opioid dependence in some patients

    – Stimulants (preferably extended release) for ADHD in some patients
