KESSO-GESIC vs TARGINIQ
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.
TARGINIQ combines naloxegol, a peripherally acting mu-opioid receptor antagonist (PAMORA), with oxycodone, a full mu-opioid receptor agonist. Naloxegol reduces opioid-induced constipation by blocking opioid effects in the gastrointestinal tract without affecting central analgesia.
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 tablet orally every 12 hours, each tablet containing oxycodone hydrochloride 10 mg and naloxone hydrochloride 5 mg (as naloxone hydrochloride dihydrate). Dose may be titrated based on analgesic requirements; maximum daily dose: oxycodone 80 mg and naloxone 40 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 terminal half-life is 3.5-4.0 hours; naloxone half-life is 1-1.5 hours. The prolonged-release formulation yields a longer apparent half-life, supporting twice-daily dosing.
Renal excretion of unchanged drug and metabolites: approximately 60% renal, 40% biliary/fecal. Major metabolites include glucuronide conjugates.
Oxycodone is primarily excreted renally as noroxycodone and free oxycodone; naloxone undergoes extensive hepatic metabolism and is excreted renally as naloxone-3-glucuronide. For TARGINIQ, approximately 87% of the dose is eliminated in urine: 19% as unchanged oxycodone, 1% as unchanged naloxone, and the remainder as metabolites. Fecal excretion accounts for ~10%.
