PERCOCET vs PERCODAN-DEMI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxycodone is a mu-opioid receptor agonist, inhibiting ascending pain pathways and altering pain perception and emotional response. Acetaminophen inhibits cyclooxygenase (COX) in the CNS, reducing prostaglandin synthesis and exerting analgesic and antipyretic effects.
Oxycodone is a full mu-opioid receptor agonist; aspirin inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis.
One tablet (5 mg oxycodone/325 mg acetaminophen) every 6 hours as needed for pain; maximum 12 tablets per day.
1 tablet (oxycodone 2.25 mg/aspirin 325 mg) orally every 6 hours as needed for pain; maximum 4 tablets in 24 hours.

Oxycodone: 3.5–4.5 hours (terminal) in normal renal function; prolonged in hepatic/renal impairment (up to 6–12 hours). Acetaminophen: 2–3 hours (terminal) in overdose, extended with hepatic injury.
Oxycodone: 3-4 hours; salicylate (aspirin): 2-3 hours at low doses, 15-30 hours at high doses; terminal half-life clinically relevant for dosing interval (q4-6h).
Oxycodone: primarily renal (up to 19% as unchanged drug, 50% as noroxycodone and oxymorphone metabolites); about 10% biliary/fecal. Acetaminophen: renal (majority as glucuronide and sulfate conjugates, about 5% unchanged).
Renal: ~90% (oxycodone: ~60% as metabolites, ~10% unchanged; aspirin: ~80% as salicylates, ~10% unchanged). Biliary/fecal: minor.
