Effects of buprenorphine in heroin addicts.

ABSTRACT

Twelve heroin addicts on the 8th day after withdrawal, and 8 healthy volunteers were given a single i.m. injection of buprenorphine 0.6 mg and their subjective response rated on 10 psychological variables. Pre-injection rating differed significantly between addicts and controls on 7 variables out of 10. Following buprenorphine more subjective changes were noted in the control group which became more calm, depressed, more aware of the environment, sleepy, tired, intoxicated, dizzy and nauseated. The drug addicts reported changes only in 2 variables (less tense and dysphoric) but otherwise showed no significant changes. These findings support the notion that buprenorphine induces low or normalizing effects in heroin addicts. This drug might thus be suitable for maintenance therapy in opiate addiction.
