KURVELO vs SEASONIQUE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KURVELO (trofinetide) is a synthetic analog of the N-terminal tripeptide of insulin-like growth factor 1 (IGF-1). It is thought to reduce neuroinflammation and normalize synaptic function by modulating the activity of microglia and astrocytes, and by enhancing the phosphatidylinositol-3-kinase (PI3K)/Akt signaling pathway.
Combination of ethinyl estradiol (estrogen) and levonorgestrel (progestin) that inhibits ovulation by suppressing gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH); increases cervical mucus viscosity and alters endometrial receptivity.
100 mg orally once daily
One tablet daily orally: 84 days of ethinyl estradiol 0.02 mg / levonorgestrel 0.1 mg (active), followed by 7 days of ethinyl estradiol 0.01 mg.

Terminal elimination half-life is 12-15 hours; requires dose adjustment in renal impairment.
Ethinyl estradiol: approximately 15.9 hours (range 9-28 hours); Levonorgestrel: approximately 24.4 hours (range 12-48 hours). Terminal elimination half-life accounts for steady-state attainment within 5-7 days.
Primarily renal excretion (70-80% as unchanged drug), with 10-15% biliary/fecal elimination.
Renal: approximately 60% (as glucuronide and sulfate conjugates); Fecal: approximately 40% (as metabolites, with enterohepatic recycling).
