“…Initially phenacetin was assumed to be the nephrotoxic common denominator (50,51,150,151), and this compound was progressively banned from over-the-counter (OTC) products, but it is now appreciated that many analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) have papillotoxic potential if used in excessive quantities. It is also apparent that the problem of excessive use of analgesics continues today (13,46,56,87,96,171,185,200,201) and this healthcare cost is probably preventable (46,47,59). Analgesic abuse is a frequent cause of analgesic nephropathy that leads to end-stage renal disease and upper urothelial carcinoma throughout Europe (46, 47, 58-64, 179,180,203,204), Australia (149-150, 171, 216), and other parts of the world (206)(207)(208)(209)(210).…”
