QOLIANA vs TYLENOL W/ CODEINE NO. 3
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Codeine is a prodrug converted to morphine, which acts as a mu-opioid receptor agonist; acetaminophen inhibits cyclooxygenase (COX) and modulates cannabinoid and serotonergic pathways, with central analgesic effect.
Initiate at 5 mg orally once daily, increase as tolerated to 10 mg once daily. Maximum dose 20 mg once daily.
1-2 tablets (300 mg acetaminophen/30 mg codeine per tablet) orally every 4 hours as needed for pain; maximum 12 tablets per day.

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).
Acetaminophen: 2-3 hours (prolonged in hepatic or renal impairment, overdose). Codeine: 2.5-3.5 hours; morphine from codeine: approx 2 hours; prolonged in hepatic or renal impairment.
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.
Acetaminophen: primarily renal (hepatic metabolism followed by renal excretion of metabolites; <5% unchanged). Codeine: renal (primarily as codeine and its metabolites, including morphine, norcodeine, and conjugated forms; 90% excreted in urine, 10% in feces).
