Opioid Dependence: A Chronic, Relapsing Brain Disease

Opioid Dependence:
A Chronic, Relapsing Brain Disease
Presentation Objectives
 Review the evidence that opioid dependence is a
chronic, relapsing disease
 Demonstrate similarities of opioid dependence to other
chronic diseases
 Emphasize the importance of accepting the chronic
disease model as an integral part of providing quality
patient care and protecting access to treatment
Features of a Chronic, Relapsing Condition
 Limited chances of complete ‘cure’ or ‘recovery’
 Relapse common
 Multifactorial
–

–
Genetic (heritable vulnerability)
Environmental (exposure)
Biological (demonstrated pathophysiology)
Behavioral (lifestyle aspects)
Optimal patient care depends on accepting opioid
dependence as a chronic, relapsing condition
No Universally Accepted Definition
of Addiction
 National Institute on Drug Abuse (NIDA)—A chronic,
relapsing brain disease characterized by compulsive
drug-seeking and use despite harmful consequences and
by long-lasting structural and functional changes in the
brain1

Benefits of the Chronic Disease Model
 Emphasizes comprehensive, sustained treatment to help
retain patients, maintain adherence, and focus on success
 Minimizes stigma associated with opioid dependence
 Promotes continuity of care
 Underscores the importance of ongoing monitoring
 Reinforces the need for a multifaceted, multidisciplinary
treatment approach

The Multifaceted Components of
Opioid Addiction
The Multiple Components of Drug Abuse
 Drug abuse has multiple
components:
– Neurobiologic1,2
– Behavioral, cognitive, and affective
 Treatment must address each
component
 Drug abuse is learned3,4
 Long-term drug use alters:
– The way people think about their
own behavior5
– Emotional reactions to
environmental stimuli5

Chemical Changes: Craving and Relapse1,2
Long-term changes in brain responsivity may remain even
after withdrawal and sustained abstinence
 Drug- and cue-induced craving are associated with
activation of critical brain regions
 Patients may always be at risk for craving and relapse
upon re-exposure to the drug or environmental cues
associated with the drug

Behavioral Components of Addictive Behavior
 Within a behavioral framework, drug use is viewed as a special case of operant
behavior maintained by the reinforcing effects of the drug1
 Learned behavior — Disrupt any element to reduce strength of behavior2
3-Term Contingency
Antecedent
Behavior
Consequence
 Drug reinforcement
– Drugs of abuse function as positive reinforcers in laboratory studies and therapeutic utility of
pharmacotherapies can be demonstrated in laboratory studies3,4
 Extinction2
– When responses no longer produce reinforcement, their rate diminishes
– Initial response to extinction is a rate increase; some behaviors are resistant

Multifaceted Treatment Approach
Treatment Goals

The Components of Treatment:
Pharmacotherapy and Psychosocial Intervention1,2
Pharmacotherapy
Can control symptoms by
normalizing brain chemistry
Psychosocial Intervention
Essential to change behaviors
and responses to environmental
and social cues that so
significantly impact relapse
Both are necessary to normalize brain chemistry, change behavior,
and reduce risk for relapse; neither alone is sufficient

Counseling Improves Outcomes:
Opioid Dependence
 Most recent updates of Cochrane Database reviews of
pharmacological interventions for opioid dependence and
medical taper with and without psychosocial treatment
– Opioid dependence: Adding psychosocial support to medicationassisted treatments improves the number of participants abstinent
at follow-up1
– Medical taper: Adding psychosocial support to medical taper
improves treatment completion and decreases opioid use2

2. Amato L et al. Cochrane Database Syst Rev. 2008;(4):CD005031. doi: 10.1002/14651858.CD005031.pub3.
Counseling Improves Outcomes:
Opioid Dependence
 Intravenous opiate users were assigned
to one of three treatments:
– Minimum methadone services (MMS;
drug alone)
– Standard methadone services (SMS;
drug + counseling)
– Enhanced methadone services
(EMS; drug + counseling + onsite
psychosocial interventions)
 Outcomes were significantly better for
the EMS group overall (EMS > SMS >
MMS)
 The figure shows the percentage of
subjects in each group with consecutive
opiate-free urine samples (“dose
response” for psychosocial services)
McLellan AT et al. JAMA. 1993;269(15):1953-1959.
Psychotherapy, Counseling, or Psychosocial Support
Improves Outcomes in Other Chronic Diseases
 Depression
– Addition of psychotherapy following initial pharmacological control of acute
symptoms of major depressive disorder confers advantage in terms of
relapse1-3
 Panic disorder
– Combined pharmacotherapy and psychotherapy is significantly superior to
pharmacotherapy alone4
 Nicotine dependence
– Provision of more intense levels of psychosocial support can facilitate
likelihood of quitting5,6
 Alcohol dependence
– Advantages of combining psychotherapy with pharmacotherapy were not
apparent during active therapy, but emerged after therapy ended6,7
 Obesity
– In the absence of a psychosocial intervention aimed at lifestyle change,
weight loss achieved through pharmacotherapy is not sustained8

Defining Counseling and Behavioral Therapy
for Opioid-Dependence Treatment
 Encompasses several types of treatment modalities
– Counseling/psychotherapy, including cognitive behavioral therapy
– Community-based support (12-step programs, Alcoholics Anonymous
[AA]/Narcotics Anonymous [NA])
– Other social support (financial, housing, life skills)
 Treatment should be individualized to address the unique
constellation of factors that impacts each patient’s condition
– Dependence history
– Comorbidities
– Existing social network
– Socioeconomic status
 Psychosocial support may continue beyond pharmacotherapy
to aid in relapse prevention

Summary
 Opioid dependence is a chronic, relapsing disease
similar to other chronic diseases
– Medication-assisted maintenance treatment is the standard
– Treatment is not time limited
 The disease is multifaceted with neurobiologic and
behavioral components
– Requires a multifaceted treatment approach
 Combining pharmacotherapy and psychosocial
interventions is critical to treat the multiple facets of the
disease
Important Safety Information
Important Safety Information
SUBOXONE® (buprenorphine and naloxone) Sublingual Film (CIII) is indicated for maintenance
treatment of opioid dependence as part of a complete treatment plan to include counseling and
psychosocial support. Treatment should be initiated under the direction of physicians qualified under
the Drug Addiction Treatment Act.
SUBOXONE Sublingual Film should not be used by patients hypersensitive to buprenorphine or
naloxone.
SUBOXONE Sublingual Film can be abused in a manner similar to other opioids, legal or illicit. Clinical
monitoring appropriate to the patient’s level of stability is essential.
Chronic use of buprenorphine can cause physical dependence. A sudden or rapid decrease in dose
may result in an opioid withdrawal syndrome that is typically milder than seen with full agonists and
may be delayed in onset.
SUBOXONE Sublingual Film can cause serious life-threatening respiratory depression and death,
particularly when taken by the intravenous (IV) route in combination with benzodiazepines or other
central nervous system (CNS) depressants (ie, sedatives, tranquilizers, or alcohol). It is extremely
dangerous to self-administer nonprescribed benzodiazepines or other CNS depressants while taking
SUBOXONE Sublingual Film. Dose reduction of CNS depressants, SUBOXONE Sublingual Film, or
both when both are being taken should be considered.
Liver function should be monitored before and during treatment.
Please see full Prescribing Information available at this presentation.
Important Safety Information (cont)
Death has been reported in nontolerant, nondependent individuals, especially in the presence of
CNS depressants.
Children who take SUBOXONE® (buprenorphine and naloxone) Sublingual Film (CIII) can have severe,
possibly fatal, respiratory depression. Emergency medical care is critical. Keep SUBOXONE Sublingual Film
out of the sight and reach of children.
Intravenous misuse or taking SUBOXONE Sublingual Film before the effects of full-agonist opioids (eg,
heroin, hydrocodone, methadone, morphine, oxycodone) have subsided is highly likely to cause opioid
withdrawal symptoms.
Neonatal withdrawal has been reported. Use of SUBOXONE Sublingual Film in pregnant women or during
breast-feeding should only be considered if the potential benefit justifies the potential risk. Caution should be
exercised when driving vehicles or operating hazardous machinery, especially during dose adjustment.
Adverse events commonly observed with the sublingual administration of SUBOXONE Sublingual Film are
numb mouth, sore tongue, redness of the mouth, headache, nausea, vomiting, sweating, constipation, signs
and symptoms of withdrawal, insomnia, pain, swelling of the limbs, disturbance of attention, palpitations, and
blurred vision.
Cytolytic hepatitis, jaundice, and allergic reactions, including anaphylactic shock, have been reported.
This is not a complete list of potential adverse events associated with SUBOXONE Sublingual Film. Please
see full Prescribing Information for a complete list.
