Tapentadol, the new kid on the block in India: Is it time to worry?

Background and Objectives: Large-scale prospective case series of tapentadol abuse or dependence in India is not available. Hence, we aimed to study the prevalence and profile of tapentadol users in a treatment-seeking population. Materials and Methods: The study had prospective and retrospective arms. We collected 8-month prospective data by face-to-face interviews (n = 70) and 8-year retrospective data from case notes (n = 26) with either tapentadol misuse/abuse or dependence in patients attending a de-addiction center. Results: The prevalence of tapentadol abuse or dependence was 25% among the pharmaceutical opioid users. Concurrent use of other opioids was seen in >80% of participants of both the arms. Major sources of tapentadol were chemists (without a prescription) (53%) and doctors (prescriptions) (40%). Patients in the tapentadol dependence group had a significantly higher dose, duration, and pharmaceutical opioid use. Conclusion: India needs awareness promotion, training, availability restriction, and provision of treatment for tapentadol abuse or dependence.
