OXYCODONE HYDROCHLORIDE AND IBUPROFEN vs WESTADONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxycodone is a full mu-opioid receptor agonist, leading to analgesia, euphoria, and sedation. Ibuprofen inhibits cyclooxygenase (COX)-1 and COX-2, reducing prostaglandin synthesis and providing analgesic, anti-inflammatory, and antipyretic effects.
Mu-opioid receptor agonist; also acts as an NMDA receptor antagonist and inhibits serotonin and norepinephrine reuptake.
One tablet containing oxycodone hydrochloride 5 mg and ibuprofen 400 mg orally every 6 hours as needed for pain; maximum 4 tablets per day.
Oral: 2.5-10 mg every 4-6 hours as needed for pain; maximum 40 mg per day.

Oxycodone: 3-5 hours; Ibuprofen: 1.8-2.5 hours. Clinical context: Oxycodone's half-life allows dosing every 4-6 hours; Ibuprofen's shorter half-life supports frequent dosing for sustained anti-inflammatory effect.
Terminal elimination half-life: 15-60 hours (mean ~24 hours). Clinical context: Prolonged half-life supports once-daily dosing in opioid maintenance; accumulation occurs with repeated dosing due to long half-life.
Oxycodone: primarily renal (87%) as metabolites, with ~19% unchanged; Ibuprofen: renal (90%) as metabolites, with ~10% unchanged; small biliary/fecal elimination for both.
Primarily renal (40-50% as unchanged methadone and its metabolites, 15-20% as metadone-N-oxide), biliary/fecal (5-10%).
