KESSO-GESIC vs PERCODAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KESSO-GESIC is a combination analgesic containing butalbital (barbiturate), acetaminophen, and caffeine. Butalbital depresses the CNS by enhancing GABA-A receptor activity, acetaminophen inhibits COX enzymes centrally, and caffeine is a CNS stimulant that may enhance analgesia.
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.
Adults: 2 tablets (325 mg acetaminophen + 5 mg hydrocodone per tablet) orally every 4-6 hours as needed for pain; maximum 8 tablets per day.
1-2 tablets orally every 4-6 hours as needed for pain. Each tablet contains oxycodone 4.5 mg and aspirin 325 mg.

Terminal elimination half-life is 2–4 hours in healthy adults. In hepatic impairment, half-life may be prolonged up to 8 hours; in renal impairment, minimal change.
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.
Renal excretion of unchanged drug and metabolites: approximately 60% renal, 40% biliary/fecal. Major metabolites include glucuronide conjugates.
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).
