TARGINIQ vs WYGESIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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 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.
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.

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.
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).
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%.
Primarily renal: 90% as unchanged drug and glucuronide conjugate; <5% fecal.
