Naltrexone induction: psychologic and pharmacologic strategies

Area of Science:

• Pharmacology
• Addiction Medicine
• Clinical Psychology

Background:

• Naltrexone is an opioid antagonist used in addiction treatment.
• High dropout rates occur during naltrexone induction and stabilization phases.
• Improving patient retention is crucial for treatment success.

Purpose of the Study:

• To describe methods for enhancing naltrexone retention during treatment induction and stabilization.
• To compare different approaches for naltrexone induction and withdrawal management.
• To identify factors contributing to patient dropout and suggest future research directions.

Main Methods:

• Review of existing literature and clinical practices for naltrexone treatment.
• Comparison of outcomes between street addicts and postmethadone patients during induction.
• Evaluation of inpatient versus outpatient withdrawal and induction strategies.
• Exploration of adjunctive pharmacologic agents like clonidine.

Main Results:

• Street addicts may benefit more from counseling during naltrexone induction compared to postmethadone patients.
• Inpatient withdrawal and induction appear more successful than outpatient methods.
• Clonidine and clonidine/naltrexone combinations show potential for improving outpatient results.
• Prolonged withdrawal symptoms and drug craving are significant contributors to dropout during stabilization.

Conclusions:

• Optimizing naltrexone retention requires addressing challenges in both induction and stabilization phases.
• Adjunctive pharmacotherapies and tailored counseling strategies are vital for improving treatment adherence.
• Further research is needed to refine outpatient naltrexone protocols and manage withdrawal symptoms effectively.
