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 receptor agonist; binds to estrogen receptors (ERα and ERβ), modulating gene transcription and promoting estrogenic effects.
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.
Intramuscular: 0.22 to 1.1 mg (220 to 1100 mcg) once weekly for menopausal symptoms; 0.5 to 2 mg (500 to 2000 mcg) once weekly for prostatic carcinoma.

The terminal elimination half-life of estradiol is approximately 13-19 hours following transdermal administration, with significant interindividual variability.
Terminal elimination half-life: 13–19 hours (mean 16 h); clinical context: supports once-daily dosing for estrogen replacement.
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; fecal: ~30% via enterohepatic recirculation; biliary: ~20%.
