Abstract

Background: Nimesulide, a preferential Cyclooxygenase-2 (COX-2) inhibitor, is frequently prescribed for musculoskeletal conditions in middle-aged (45–64 years) and older adults (≥65 years). Given age-associated alterations in drug metabolism, polypharmacy, and comorbidities, its safety and efficacy in adults >45 years warrants critical re-evaluation.

Objectives: To systematically synthesize and appraise evidence on the safety, tolerability, and therapeutic efficacy of oral nimesulide in adults >45 years across diverse pain-related indications, with emphasis on gastrointestinal, hepatic, renal, and cardiovascular risk domains.

Methods: A comprehensive systematic search of PubMed and Google Scholar in accordance to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 guidelines, was conducted from inception through August 2025. Eligible studies included randomized controlled trials, observational studies, and pharmacovigilance datasets. Safety and efficacy outcomes were assessed.

Results: Thirty-four studies encompassing osteoarthritis, lower back pain, musculoskeletal disorders, and oral surgical pain were analyzed. Nimesulide in controlled trials demonstrated gastrointestinal tolerability. Hepatic adverse events were uncommon in interventional studies; however, pharmacovigilance signals indicated a low but measurable incidence of drug-induced liver injury, consistent with nonsteroidal anti-inflammatory drugs (NSAIDs) class effects. Renal and cardiovascular safety outcomes were comparable to other NSAIDs, with no consistent evidence of excess risk. Fixed-dose combinations with paracetamol exhibited favorable tolerability. Analgesic efficacy was consistent, with rapid onset and pain reduction.

Conclusion: Nimesulide demonstrated a favorable short-term safety profile in adults >45 years, with low incidences of serious gastrointestinal, hepatic, renal, and cardiovascular abnormalities. Pharmacovigilance data indicated monitoring of hepatic abnormalities. Evidence supports short-term tolerability, while emphasizing the importance of age-specific safety studies.
