2-4 hours (terminal half-life). Clinical context: Requires dosing every 6-8 hours for sustained effect; no accumulation with normal hepatic function.
Terminal elimination half-life: 10-20 hours; context: allows twice-daily or once-daily dosing for chronic pain or inflammation.
Renal (primarily as glucuronide conjugates and inactive metabolites; <10% unchanged). Biliary/fecal elimination is negligible.
Renal: 50-60% as metabolites and conjugates; biliary/fecal: ~5%; remainder uncharacterized.
