Non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequently used agents to treat musculoskeletal disorders (principally by the elderly), thus raising the risk of adverse drug reactions (ADRs). This work aims to monitor NSAIDs safety profile in older people by using literature and pharmacovigilance data. Published clinical studies reporting the NSAIDs safety in elderly patients (age ≥ 65) were identified by a literature search and were then deeply analyzed. In addition, suspected ADRs reports submitted to the Portuguese Pharmacovigilance System (PPS) involving patients aged ≥65 with at least one NSAID as suspected drug were explored in detail. Most studies concluded that the risk of gastrointestinal, cardiovascular, and renal ADRs was significantly lower with cyclooxygenase-2 (COX-2)-selective NSAIDs use than with nonselective NSAIDs. The PPS data analysis showed that serious gastrointestinal ADRs occurred mostly in patients taking more than one NSAID and/or another concomitant drug that increases the incidence of these events, in the absence of gastroprotection. The results suggest that while NSAID toxicity is well understood, their safe use needs to be monitored in clinical practice. Furthermore, the pharmacovigilance data analyzed also showed that monitoring NSAIDs use in elderly remains essential to mitigate the associated risks, especially in those with comorbidities and under polytherapy.
