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.
Estrone binds to and activates estrogen receptors (ERα and ERβ), leading to modulation of gene transcription and subsequent estrogenic effects on target tissues.
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.
0.1 to 0.5 mg intramuscularly 2 to 3 times per week for estrogen replacement therapy

The terminal elimination half-life of estradiol is approximately 13-19 hours following transdermal administration, with significant interindividual variability.
Terminal half-life: 24-48 hours (prolonged due to enterohepatic recirculation and tissue distribution).
Estradiol is primarily excreted in urine as glucuronide and sulfate conjugates (approx. 90%), with the remainder excreted in feces via bile (approx. 10%).
Renal: ~50% (as glucuronide and sulfate conjugates), Biliary/Fecal: ~50% (enterohepatic recirculation).
