An Open-label, Prospective, Multicentric, Cohort Study of Nimesulide/Paracetamol Fixed Drug Combination for Acute Pain Management: Sub-group Analysis.

OBJECTIVE: Nimesulide has been evaluated in numerous clinical studies in the management of a variety of acute painful conditions. However, there is limited Indian data available on the nimesulide/paracetamol fixed drug combination (FDC). Hence, an open-label prospective multicentric study was conducted to evaluate the safety and efficacy of this FDC in the management of acute painful conditions in real-world settings.

MATERIALS AND METHODS: A prospective, open-label, and multicenter study conducted at 24 centers across Indian patients with acute painful conditions due to trauma, tendinitis, myalgia, low backache, sprains, pulled muscle, soft tissue injury, dental pain, and dental procedure/surgery. Nimesulide/paracetamol FDC was prescribed by clinicians as a part of routine practice. The effectiveness was evaluated on the numerical rating scale (NRS), that is, pain intensity at rest and movement, and the physician/patient global assessment scale (GAS) among the subgroups of acute painful conditions like myalgia, dental pain, low backache, etc. Hepatic safety was also evaluated among the subgroups at the end of treatment.

RESULT: A total of 464 patients were included in the study. The reduction in NRS score at rest and movement during treatment duration across different types of pain was statistically significant (p < 0.001). Pain reduction was evident as per patient and physician GAS at the end of treatment in all indications. No clinically significant difference was found in liver parameters at the end of the study. Nimesulide/paracetamol (FDC) was well tolerated across all the subgroups.

CONCLUSION: Nimesulide/paracetamol FDC was found to be well-tolerated and effective in pain management across all acute painful conditions in a real-world setting without any hepatic safety concerns.
