Patients and methods: This cross-sectional study was conducted from 2010 to 2016 using the prescription databases of two tertiary hospitals in Malaysia. Prescriptions for nine NSAIDs (ketoprofen, diclofenac, celecoxib, etoricoxib, ibuprofen, indomethacin, meloxicam, mefenamic acid, and naproxen), tramadol, and five other opioids (morphine, fentanyl, oxycodone, dihydrocodeine, and buprenorphine) were included in this study. Annual number of patients and prescriptions were measured in repeat cross-sectional estimates. Descriptive statistics and linear trend analysis were performed using Stata version 13. Results: A total of 192,747 analgesic prescriptions of the nine NSAIDs, tramadol, and five other opioids were given for 97,227 patients (51.8% NSAIDs patients, 46.6% tramadol patients, and 1.7% opioid patients) from 2010 to 2016. Tramadol (37.9%, n=72,999) was the most frequently prescribed analgesic, followed by ketoprofen (17.5%, n=33,793), diclofenac (16.2%, n=31,180), celecoxib (12.2%, n=23,487), and other NSAIDs (<4.5%). All the analgesics were increased over time except meloxicam, indomethacin, and mefenamic acid. Opioids, primarily morphine (2.2%, n=4,021) [...]
