Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxycodone is a full opioid agonist with relative selectivity for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia. Oxycodone acts on the central nervous system (CNS) to produce analgesia. Aspirin inhibits cyclooxygenase, leading to decreased prostaglandin synthesis, which reduces pain and inflammation.
Oxycodone is a full mu-opioid receptor agonist; aspirin inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis.
1-2 tablets orally every 4-6 hours as needed for pain. Each tablet contains oxycodone 4.5 mg and aspirin 325 mg.
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 hours, prolonged in elderly, hepatic/renal impairment. Aspirin: 2-3 hours at low doses; 15-30 hours at anti-inflammatory doses due to saturable metabolism.
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 (65-87% as parent and metabolites, mostly noroxycodone and oxymorphone conjugates); ~10% fecal. Aspirin: renal (75-90% as salicylates and metabolites, dose-dependent).
Renal: ~90% (oxycodone: ~60% as metabolites, ~10% unchanged; aspirin: ~80% as salicylates, ~10% unchanged). Biliary/fecal: minor.
