Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Estradiol is a steroid hormone that binds to and activates estrogen receptors (ERα and ERβ), modulating gene transcription and non-genomic signaling pathways. It replaces endogenous estrogen in postmenopausal women.
Estrogen replacement therapy; binds to estrogen receptors (ERα and ERβ), modulating gene transcription and exerting effects on reproductive tissues, bone density, and cardiovascular system.
Initial dose: 0.025 mg/day applied once weekly to clean, dry, non-irritated skin on lower abdomen or upper buttocks. Titrate based on symptoms. Maximum dose: 0.1 mg/day.
1.25 mg orally once daily for 3 weeks, followed by a 1-week rest period; cyclic therapy.

The terminal elimination half-life of estradiol is approximately 13-19 hours following transdermal administration, with significant interindividual variability.
Terminal elimination half-life: 10–24 hours (mean ~15 h); clinically, steady-state achieved in 5–7 days
Estradiol is primarily excreted in urine as glucuronide and sulfate conjugates (approx. 90%), with the remainder excreted in feces via bile (approx. 10%).
Renal: 95% (as glucuronide and sulfate conjugates); biliary/fecal: ~5%
