The market taxonomy by drug type stratifies molecules on mechanism, patent status, and reimbursement risk. NSAIDs constitute 61 % of 2023 revenues; within the class, non-selective NSAIDs (ibuprofen, diclofenac, naproxen) hold 46 %, pressured by genericisation, whereas COX-2 inhibitors (celecoxib, etoricoxib) retain 15 % thanks to cardiovascular-safety positioning in chronic arthritis. Paracetamol (acetaminophen), used ubiquitously for fever and mild pain, captures 25 % of sales value but >60 % of volume, reflecting ultra-low per-unit prices. Salicylates—mainly high-dose aspirin—represent 7 %, increasingly confined to secondary cardioprotection rather than analgesia. Pyrazolones (metamizole) contribute 4 %, concentrated in Latin America and parts of Europe where generic availability offsets lingering agranulocytosis concerns. Combination drugs (paracetamol+codeine, NSAID+caffeine) add 3 %, yet exhibit the steepest price erosion as regulators tighten codeine scheduling.
