PERCODAN vs VICOPROFEN
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.
Hydrocodone is a mu-opioid receptor agonist that activates G-protein coupled opioid receptors, leading to analgesia; ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that 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 (hydrocodone 5 mg / ibuprofen 200 mg) orally every 4 to 6 hours as needed for pain; maximum 5 tablets per day.

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.
Hydrocodone: 3.8-4.5 hours (immediate-release); clinical context: analgesic duration correlates with half-life, but may be prolonged in renal/hepatic impairment. Ibuprofen: 2-4 hours (immediate-release); clinical context: anti-inflammatory effect may outlast plasma half-life due to tissue distribution.
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).
Hydrocodone: primarily renal (26% as unchanged drug and metabolites, including norhydrocodone, hydromorphone, and conjugates); less than 5% fecal. Ibuprofen: renal (50-60% as unchanged drug and metabolites, mainly conjugated with glucuronic acid; <10% unchanged); biliary/fecal (minor).
