Drug discrimination methods in human drug abuse liability evaluation

Area of Science:

• Pharmacology
• Neuroscience
• Behavioral Science

Background:

• The drug discrimination paradigm, used in animal models, assesses subjective drug effects.
• This method has been adapted for human subjects to evaluate drug similarity.

Purpose of the Study:

• To review methods for human drug discrimination studies.
• To assess the utility of this procedure in predicting drug abuse liability.

Main Methods:

• Review of general methods in human drug discrimination studies.
• Examination of drugs tested and design considerations for human studies.
• Analysis of evidence for the procedure's utility in abuse liability assessment.

Main Results:

• Human drug discrimination provides a direct measure of stimulus similarity between drugs.
• This information is valuable for predicting the abuse liability of new compounds.
• The review covers methods, tested drugs, design factors, and utility evidence.

Conclusions:

• Human drug discrimination is a valuable tool for assessing drug abuse liability.
• Further research is required to validate the procedure and optimize its application.
• The method aids in understanding stimulus generalization and predicting abuse potential.
