OXYCODONE 2.5/APAP 500 vs QOLIANA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxycodone is a mu-opioid receptor agonist that inhibits ascending pain pathways and alters pain perception. Acetaminophen inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis.
QOLIANA (elagolix) is a nonpeptide, orally active gonadotropin-releasing hormone (GnRH) receptor antagonist that competitively binds to GnRH receptors in the pituitary gland, thereby reducing the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This leads to decreased ovarian production of estrogen and progesterone, resulting in a hypoestrogenic state.
1-2 tablets (oxycodone 2.5-5 mg/APAP 500-1000 mg) orally every 4-6 hours as needed for pain; maximum APAP 4000 mg/day (consider lower APAP limit per institutional guidelines).
Initiate at 5 mg orally once daily, increase as tolerated to 10 mg once daily. Maximum dose 20 mg once daily.

Oxycodone: 3.5-5.5 hours in healthy adults; steady state reached within 24 hours. Acetaminophen: 2-3 hours; prolonged in hepatic impairment.
Terminal elimination half-life is 12 hours (range 10–15 hours) in healthy adults; may extend to 18–24 hours in patients with moderate hepatic impairment (Child-Pugh B).
Oxycodone: primarily renal (87% as metabolites, 10% unchanged). Acetaminophen: primarily renal (90-100% as glucuronide and sulfate conjugates, 2-5% unchanged). Fecal elimination <10%
Renal excretion of unchanged drug accounts for approximately 30% of elimination; biliary/fecal excretion accounts for 60% (including metabolites); 10% is metabolized with negligible pulmonary elimination.
