Abstract
[b] AIM: [/b] The aim of the study is to compare quetiapine with placebo along with oral naltrexone in the treatment of opioid dependent patients. We conducted the study as opioid dependence is steadily increasing in this area and more research is needed to prevent relapse after opioid detoxification.[b] SETTINGS AND DESIGN[/b]: It is a double blind placebo controlled , randomized study that was conducted in department of psychiatry, de addiction unit (Sri Guru Ram Das Institute of Medical Sciences & Research, Sri Amritsar) over one year time period. All the patients who were taken in the study had a confirmed diagnosis of opioid dependence as per ICD 10 criteria. [b]MATERIAL AND METHOD[/b]: It is a double blind, placebo controlled, randomized study. A total of 217 subjects were admitted over year, out of which 164 were screened as 53 subjects refused to participate. Out of 164 randomization of 152 patient was done and two groups (1&2) were made. . During detoxification, opioids were given to both groups and stopped after 1-2 weeks. Then all patients were started on Naltrexone 50 mg/day. Group 1 (n=73) received naltrexone (50mg/day) plus quetiapine (50-200mg/day), while group 2 (n=79) received naltrexone (50mg/day) plus placebo (multivitamin) for next 26 weeks. Our primary efficacy measures were relapse rate and percent days of abstinence. Two groups were compared with the help of percentage method and independent t test done. [b]RESULTS[/b]: Relapse rate in placebo group was almost twice to that of Quetiapine group. In group 1, 24 subjects (32.87%) had relapsed by the end of 6 months as compared to 56 subjects (70.88%) in group 2. Percent days of abstinence in Quetiapine group were significantly higher as compared to placebo group. [b]DISCUSSION: [/b]Our study shows significant advantages in using Quetiapine along with Naltrexone to decrease relapse rate and increase percent days of abstinence after inpatient detoxification.
