Estradiol binds to and activates estrogen receptors (ERα and ERβ), leading to modulation of gene transcription and regulation of target tissues including reproductive, cardiovascular, skeletal, and CNS systems.
Estradiol is a steroid hormone that binds to and activates estrogen receptors (ERα and ERβ), leading to regulation of gene transcription and modulation of various physiological processes including reproductive function, bone metabolism, and cardiovascular health.

Terminal half-life: 12-18 hours for estradiol; clinical context: once-daily or twice-weekly dosing maintains steady-state concentrations.
12-18 hours (terminal elimination half-life); clinical context: dosed once daily, steady-state achieved in 5-7 days.
Renal: 80-90% as glucuronide and sulfate conjugates; Fecal: 10-20% via bile; <1% unchanged.
Renal elimination (90-95%) as glucuronide and sulfate conjugates; fecal (5-10%) via biliary excretion.
