Clinical Trial Summary

The purpose of this study is to determine whether the opportunity to take free supplemental hydromorphone (HYD) influences drug seeking behavior in heroin dependent individuals.


Clinical Trial Description

Drug dependence is a condition in which drug seeking holds a higher priority than behaviors controlled by other reinforcers. Learning to understand, predict, and control this maladaptive choice behavior may lead to improved prevention and treatment strategies. HYD is a drug currently used as a cough suppressant and to relieve pain. The purpose of this study is to determine the extent to which opioid drug seeking behavior in heroin dependent individuals can be reduced by environmental factors, including supplemental opioid drug availability, drug price, and non-drug alternative reinforcers. Specifically, this study will determine whether pre-session opportunity to take "free" supplemental HYD influences HYD seeking by using a choice progressive ratio schedule as well as by varying the dose of HYD.

Participants in this observational study will undergo multiple test sessions in which they will select between acquiring drug or money. Because participants may choose money on all 12 trials of test sessions as a way to avoid receiving an injection, a placebo injection will be given when money is chosen. Prior to each test session, participants will receive a sample of the drug dose. During each test session, participants will have 12 opportunities to select either drug (administered as HYD) or money. Prior to each individual choice trial, participants will receive supplemental HYD. Participants will use a computer to earn choices. Respiration rate, oxygen saturation, heart rate, and blood pressure will be monitored throughout choice trials. Pupil diameter will be measured with a digital camera. Participants will complete self-report questionnaires at different times during the study. Participants will be maintained on buprenorphine throughout the study, with a fixed 3-week detoxification after study completion. ;
