Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Etonogestrel is a progestin that suppresses gonadotropin release, inhibiting ovulation and increasing cervical mucus viscosity.
Ethinyl estradiol and norelgestromin (the active metabolites of norgestimate) suppress gonadotropin release, inhibiting ovulation and increasing cervical mucus viscosity, impairing sperm penetration.
One 13.9 mg subcutaneous etonogestrel implant inserted into the inner side of the non-dominant upper arm for contraception; effective for 3 years.
Apply 1 patch (20 cm² containing 600 mcg ethinyl estradiol and 6 mg norelgestromin) transdermally once weekly for 3 weeks, followed by 1 patch-free week.

Terminal elimination half-life is approximately 1.3–1.7 hours (mean 1.5 hours). The short half-life supports continuous intravenous infusion for sustained sedation in critical care.
Terminal elimination half-life is 4.5 hours; in severe renal impairment (CrCl <30 mL/min), half-life may be prolonged up to 12-15 hours, requiring dose adjustment.
Renal excretion of metabolites accounts for approximately 85–90% of elimination; biliary/fecal excretion accounts for 10–15%.
Primarily renal (approximately 60-70% as unchanged drug), with biliary/fecal elimination accounting for 20-30%.
