Clinical Matrix

Mechanism of Action

Estrone is a natural estrogen that binds to estrogen receptors (ERα and ERβ) in target tissues, modulating gene expression and exerting estrogenic effects on reproductive, skeletal, and cardiovascular systems.

Estrogen receptor agonist; binds to estrogen receptors, modulating gene transcription and cellular proliferation in target tissues.

Clinical Dosing

For menopausal hormone therapy: 0.625-5 mg orally once daily; or 0.1-0.5 mg transdermally once weekly; or 2.5-5 mg intramuscularly every 2-4 weeks.

1 to 2 mg orally once daily; for testosterone replacement in adult males, 2 to 4 mg orally once daily.

Direct Interaction

None Documented

Half-Life

Terminal elimination half-life is 24-36 hours; due to enterohepatic recirculation and slow clearance of conjugates, clinical effects persist for several days after discontinuation.
