CO-GESIC vs WYGESIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CO-GESIC (hydrocodone/acetaminophen) is a combination analgesic. Hydrocodone is an opioid agonist that binds to mu-opioid receptors in the CNS, inhibiting ascending pain pathways and altering pain perception. Acetaminophen inhibits cyclooxygenase (COX) enzymes in the CNS, reducing prostaglandin synthesis and elevating pain threshold.
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.
1-2 tablets (hydrocodone 5 mg/acetaminophen 500 mg 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 approximately 2–4 hours in adults with normal renal function; prolonged in renal impairment.
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).
Primarily renal (60–70% as unchanged drug and metabolites); minor biliary/fecal excretion (<5%).
Primarily renal: 90% as unchanged drug and glucuronide conjugate; <5% fecal.
