Primary Purpose: The presentation will review results
of five randomized double-blind placebo controlled
randomized clinical trials of different drug formulations of
naltrexone we have been doing within the last 12 years:
Oral, implantable and injectable.
1st study: Double blind placebo controlled randomized clinical trial of oral naltrexone vs placebo. 2nd study: Four cell double blind double dummy placebo controlled randomized clinical trial of combination of naltrexone with fluoxetine vs. naltrexone, fluoxetine and double placebo. 3rd study: Four cell double blind double dummy placebo controlled randomized clinical trial of combination of naltrexone with guanfacine vs. naltrexone, guanfacine and double placebo. 4th study: Three cell double blind double dummy placebo controlled randomized clinical trial of naltrexone implant vs. oral naltrexone and double placebo (oral and implantable). 5th study: Double blind placebo controlled randomized clinical trial of injectable naltrexone vs. placebo.
Summary of results: Oral naltrexone in Russia is more effective for relapse prevention and abstinence stabilization than placebo basically due to family involvement in the control of compliance. Combining naltrexone with antidepressants or guanfacine does not improve outcome significantly. Long acting sustained release naltrexone formulations (injectable and implantable) are substantially more effective than oral naltrexone or placebo for relapse prevention in opiate addicts as they make control of compliance easier.
Conclusion: Extended release formulations of naltrexone are the most effective abstinence-oriented pharmacotherapies for opiate dependence.
