PAPA-DEINE #3 vs PERCODAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetaminophen produces analgesia and antipyresis via central COX-2 inhibition and activation of descending serotonergic pathways. Codeine is a prodrug converted to morphine, a mu-opioid receptor agonist, which inhibits ascending pain pathways and alters pain perception.
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.
1-2 tablets orally every 4-6 hours as needed for pain, not to exceed 12 tablets in 24 hours. Each tablet contains acetaminophen 300 mg, codeine phosphate 30 mg.
1-2 tablets orally every 4-6 hours as needed for pain. Each tablet contains oxycodone 4.5 mg and aspirin 325 mg.

Codeine: 2.5-3 hours; Acetaminophen: 2-3 hours; Morphine (active metabolite): 2-3 hours. In hepatic impairment, codeine half-life may extend to 4-6 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.
Primarily renal (90% as glucuronide conjugates, 10% as morphine, codeine, and norcodeine). Biliary/fecal elimination accounts for <5%.
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).
