Comparing the Efficacy of Adding Buprenorphine with Placebo in Reducing Craving in Methamphetamine Dependent Patients during Treatment with Matrix Model
We investigated the efficacy of adding Buprenorphine or placebo in reducing the usage tendency in methamphetamine-depended patients during treatment with Matrix program. Inclusion criteria include men and women age 18–40 years old who were diagnosed with methamphetamine dependency according to DSM-IV criteria and exclusion criteria include a current neurological or axis I psychiatric disorders not due to substance abuse that would impair ability to participate safely in the study and subjects who met DSM-IV criteria for opiates dependence. The 40 subjects were selected from patients who referred to Addiction Treatment Center of Isfahan Noor hospital to attend meetings of matrix program during 2012 to 2013. After screening the subjects were participated in matrix program and randomly were divided into two groups of Buprenorphine and placebo. A 4-months program of intervention was arranged for each group and they were visited by a psychiatrist every two weeks. Buprenorphine began at a dose of 2 mg per day and increased to 6 mg within 7 days (3 sublingual tablets) and this amount continued for 4 months. The craving was assessed by Cocaine Craving Questionnaire-Brief (CCQ-Brief) at screening and every 2 weeks.
