Introduction to Medication Assisted Treatment Michael Dulitz, MPH, NRP Opioid Response Project Coordinator Foundation Addiction is a chronic relapsing brain disease characterized by compulsive use of a substance despite negative consequences Despite being a chronic disease, addiction is treatable, and individuals Addiction is more common than we see, 10%can of adults the criteria enter meet remission for a substance use disorder in their lifetime. Only 25% of those that
met the criteria for a use disorder ever received care. Addiction is a brain disease Stimulants Opioids Alcohol Dopamine Opioid receptor stimulation Substances that cause addiction primarily work on 2 receptor types Dopaminergic Opioid (primarily the mu receptor) Endorphins Neurotransmitters Reward/Dependence/
Loss of Control Substance Use Disorder/ Addiction Dopamine Opioids Endorphins (endogenous opioids) Exogenous (introduced from outside) Addiction is a brain disease When we do things that help us survive, we release neurotransmitters These neurotransmitters create a feeling of wellbeing and create trigger memory creation Receptors for these transmitters are located throughout the body, but
substance use disorders affect: Limbic system Dopamine/Endorphin model Life affirming activities produce a small spike of dopamine ~50% increase with eating ~100% increase with sex Dopamine levels between 50-100 pg/mL at baseline Substances spike this dopamine level Morphine ~300% increase Heroin ~1,000% increase Methamphetamine ~9001,000% increase Dopamine/Endorphin model
With chronic use, the brain adjusts to the new normal. Decreases baseline dopamine production Creates more dopamine receptors Result: brain needs more of the substance to generate the same response Life affirming activities do not create enough dopamine to trigger proper brain function, impulse control is also lost The individual will do whatever is needed to obtain the substance Dopamine/Endorphin model
With chronic use, objective eventually becomes to find enough of the substance to feel normal and avoid withdrawal When substance is not present, physical withdrawal occurs Memory Loss of memory cues Charlie Brown Effect Dopamine/Endorphin model Objectives of Agonist-based Medication Assisted Treatment for Opioid Use Disorder Return the brain to a normal baseline dopamine level Use long-acting medication to prevent spikes in dopamine Stop cravings for a substance
Allow the addressing of psychosocial needs Three FDA Approved Medications for OUD Methadone Full agonist Buprenorphine Partial agonist Naltrexone - Antagonist Dopamine/Endorphin model High dopamine recovery Individuals with strong recovery supports Highly motivated to enter treatment Predictable recovery path Most addiction treatment success data is from these groups
May do well with abstinence based treatment Low dopamine recovery Unmet psychological, social, or economic needs Unaddressed ACEs or other trauma Uncertain recovery supports Low treatment retention rates in traditional or abstinence based treatment Best candidates for Dopamine/Endorphin model Lack of
dopamine drives common behaviors seen in addiction Augmentation of dopamine is logical in a disease process related to dopamine deficiency We have FDA approved medications to safely increase dopamine
This allows cravings to be stabilized Allowing for behavioral therapy to be effective Methadone Full opioid receptor activation Treatment goal: Activate the opioid receptors to the point that the individual does not experience opioid cravings, is not in withdrawal, and is not experiencing euphoria. Duration of action: 1-2 days Can only be provided through Opioid Treatment Programs (OTPs) Closest in Fargo (3-4 people drive daily from Grand Forks)
Must dose in person and earn privileges Prevents diversion Liquid form used almost exclusively Methadone Oldest and most studied medication for opioid addiction. Ideal candidates: Individuals with exceptionally high opioid use histories Individuals with treatment retention difficulties Individuals who were unable to tolerate buprenorphine treatment Large barriers to treatment in Grand Forks due to a lack of OTPs Dose Response Methadone
Loaded High Abnormal Normality Normal Range Comfort Zone Subjective withdrawal Sick Objective withdrawal 0 hrs. Time 24 hrs. Buprenorphine Partial receptor activator Treatment goal: Activate the opioid receptors to the point that the individual does not experience opioid cravings and is not in
withdrawal. Duration of Action: ~24 hours Sublingual tablet, dissolves in 10-20 minutes, onset of action in 30 minutes Very high affinity for receptor sites Will kick most existing opioids off their receptor -> Precipitated withdrawal Buprenorphine Oftentimes combined with naloxone to prevent injection use Common Forms: Subutex (buprenorphine) sublingual tablet - > Pregnant women Suboxone (buprenorphine/naloxone) sublingual film - > Most Common Zubsolv
(buprenorphine/naloxone) sublingual tablet - > NDMA Sublocade (buprenorphine) extended release injection - > New to market, $$$$ Buprenorphine Only DATA 2000 Waivered prescribers can prescribe this medication Treatment initiation Must be started when in mild withdrawal generally 8-16 hours from last opioid use Initial dose typically 4-8mg, up to 16mg 3-4 day follow up, then titrate dose up Optimal maintenance dose 8-24mg Treatment course Individually designed taper 6
months lifetime Naltrexone Full receptor antagonist, reverses and caps the opioid receptor Structurally similar to naloxone Treatment goal: Remove the ability to use a substance by removing the euphoric effects of taking the substance FDA approved for opioid addiction and alcohol addiction Available as a oral tablet and as an extended release injectable (Vivitrol) Oral form is cheap, but has low treatment compliance Naltrexone In one major study, extended release naltrexone is similar to
buprenorphine or methadone in treatment retention BUT: Fewer received the first dose of Naltrexone (failed before initiating study) 7-10 day opioid free period required Relapse more likely in intention to treat analysis More overdoses, fewer fatal overdoses though Less treatment retention after study period Naltrexone Ideal candidates for extended release naltrexone Individuals who are highly motivated and well supported in their recovery Safety net Individuals who continue to work in professions which prohibit the use of other MAT medications Airline pilots/Physicians
Individuals who have already gone through a opioid detoxification period and/or are opposed to opioid agonist therapy Individuals with alcohol use disorder Naltrexone Dopamine and naltrexone Naltrexone does not assist in returning the body to its baseline dopamine level normal feeling Opioid cravings may persist despite inability to use opioids for euphoria Naltrexone inhibits endorphins from acting in the body resulting in a dull affect Depression Bottom line Vivitrol has definite value for select clients, but is not the nobrainer it seems at face value,
though for some it is the best solution Alkermes heavily markets Vivitrol to abstinence based providers, jails, drug Nicotine use disorder Medication assisted treatment readily available for nicotine use disorder Nicotine replacement Provides a baseline level of nicotine to prevent cravings and withdrawal Allows the individual to address the factors that lead to smoking and reprogram behaviors associated with smoking Other medications Chantix (varenicline) Wellbutrin (buproprion) Individuals are more successful in
recovery when they quit smoking at the same time Treatment Addiction is a complex but treatable disease that affects brain function and behavior. Treatment needs to be readily available and attend to the multiple needs of the individual. No single treatment is appropriate for everyone. Group-based peer support Treatment philosophies vary!
