Which medications are suitable for agonist drug maintenance?

Area of Science:

• Addiction medicine
• Pharmacology
• Neuroscience

Background:

• Agonist maintenance treatment is a key strategy for managing psychoactive drug dependence.
• Evaluating the suitability of various drug classes for this treatment is crucial for effective addiction management.

Purpose of the Study:

• To assess the feasibility of agonist maintenance therapy for major psychoactive drug classes.
• To determine which drug classes possess the necessary pharmacological and neurocognitive properties for successful maintenance treatment.

Main Methods:

• Eight clinical criteria were used to evaluate drug classes: pharmacological aspects (agonist, stability, dose-response, non-toxicity) and neurocognitive sequelae (psychiatric, cognitive, craving, salience).
• Each major drug class (opioids, nicotine, benzodiazepines, cannabis, psychostimulants, alcohol) was assessed against these eight criteria.

Main Results:

• Opioids and nicotine met all eight criteria, indicating strong potential for maintenance therapy.
• Cannabis (five criteria) and benzodiazepines (five criteria) showed partial suitability, with caveats regarding long-term cognitive effects and safe administration.
• Psychostimulants (three criteria) and alcohol (one criterion) were deemed poor candidates due to unfavorable pharmacological and neurocognitive profiles.

Conclusions:

• Drug classes differ significantly in their suitability for agonist maintenance treatment.
• Nicotine and cannabis, though not widely used currently, demonstrate potential for future maintenance roles.
• The inherent properties of certain drug classes make them unsuitable for agonist maintenance regimens.
