KESSO-GESIC vs WYGESIC
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.
WYGESIC (ibuprofen and hydrocodone) combines a nonsteroidal anti-inflammatory drug (ibuprofen) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, and a narcotic analgesic (hydrocodone) that acts as a mu-opioid receptor agonist.
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 (paracetamol 325 mg / tramadol 37.5 mg) orally every 4-6 hours as needed for pain, not to exceed 8 tablets per day.

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.
3–4 hours in healthy adults; prolonged to 5–6 hours in moderate renal impairment (CrCl 30–50 mL/min) and >11 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion of unchanged drug and metabolites: approximately 60% renal, 40% biliary/fecal. Major metabolites include glucuronide conjugates.
Primarily renal: 90% as unchanged drug and glucuronide conjugate; <5% fecal.
