FENTANYL-75 vs QOLIANA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fentanyl is a mu-opioid receptor agonist, producing analgesia and sedation by activating G-protein coupled opioid receptors in the central nervous system, leading to decreased neurotransmitter release and hyperpolarization of neurons.
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.
Apply 75 mcg/h transdermally every 72 hours for opioid-tolerant patients; not for acute pain. Rotate application site.
Initiate at 5 mg orally once daily, increase as tolerated to 10 mg once daily. Maximum dose 20 mg once daily.

Terminal elimination half-life: 3-12 hours (mean ~7 hours); prolonged in elderly, hepatic impairment, or continuous infusion.
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).
Renal: ~75% as metabolites (primarily norfentanyl) and ~10% unchanged; fecal: ~9%; biliary: minor.
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.
