Gabapentin Effect on Pain Associated with Heroin Withdrawal in Iranian Crack: a Randomized Double-blind Clinical Trial

Gabapentin seems to be a safe and well tolerated medication for treating heroine dependence. This study examined the efficacy of gabapentin for relieving withdrawal-related pain due to heroin use.Sixty men were recruited from an inpatient psychiatric ward of Fatemieh hospital in Semnan and randomized to receive either placebo (n = 30) or gabapentin (1800 mg/day) (n = 30) for 7 days. Subjective Opioid Withdrawal Scale (SOWS) was measured as a self-administered scale for grading body pain at baseline, and on days 1, 2, 3, 4, 6, and 7.Mean of pain score had a significant decrease trend in both gabapentin and placebo groups. Pain severity during the most of detoxification duration was significantly lower in gabapentin group compared with the placebo group.It is suggested that gabapentin may have an effective role in removing heroin withdrawal-related pain.
