Abuse liability of gabapentin in the Saudi population after the pregabalin restriction: A cross-sectional study

Abstract

Objective: Following the recently conducted local studies on the growing misuse of pregabalin, Pregabalin misuse has received national attention. These studies have led to the authorities restricting the availability of pregabalin to hospital pharmacies alone. While the recent epidemiological studies and case reports found gabapentin to be misused worldwide, it was previously presumed to be free of any abuse potential. This study assesses the likelihood of there being a diversion to Gabapentin abuse following the Pregabalin restriction in Jeddah, KSA. Methods: A cross sectional observational study was conducted between November 2017 and December 2017 using a self-constructed online survey via Twitter and WhatsApp. The survey items included participants’ demographics, additional history, Gabapentin for nonmedical use (frequency, concurrent use with other drugs, and motivators), and how the participants knew about the Gabapentin misuse. The data was subjected to a descriptive analysis via the utilization of frequencies and percentages. The analysis was carried out by using SPSS V21. Results: Data of the 370 respondents who took the surveys were collected. Most of the respondents were women (n ¼ 289; 78.1%) and below the age of 30 years (n ¼ 300; 81.1%). A total of 72 respondents (19.5%) had a history of psychoactive drug abuse. Ten of the respondents reported Gabapentin misuse (2.7%). Half of the participants reported prior Pregabalin misuse, and were unemployed. Most of the misusers (n ¼ 8; 80%) came to know about the psychotropic effects of Gabapentin from friends. The most common motives for using it were to ‘have fun’ and ‘peer pressure’ (n ¼ 6; 60%). Half of the misusers used Gabapentin on a weekly basis. Conclusion: The findings of our study suggest a potential diversion from Pregabalin to Gabapentin misuse. Regulations and periodic reviews of the psychoactive prescription medications available in the community pharmacies are essential.
