Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Estrogen receptor agonist; binds to estrogen receptors, modulating gene transcription and cellular proliferation in target tissues.
Estrogen replacement therapy; estrogen binds to estrogen receptors, which then translocate to the nucleus and modulate gene transcription, leading to effects such as proliferation of the endometrium and regulation of gonadotropin secretion.
1 to 2 mg orally once daily; for testosterone replacement in adult males, 2 to 4 mg orally once daily.
0.625 mg orally once daily

Terminal elimination half-life is approximately 12-14 hours, supporting once-daily dosing in clinical use.
Estrone: 10-24 hours; equilin: 12-18 hours; terminal half-life supports once-daily dosing.
Primarily renal; ~40% as unchanged drug and glucuronide conjugates. Biliary/fecal elimination is minor (~10-15%).
Renal (primarily as glucuronide and sulfate conjugates, ~50-80% of a dose), fecal (~10-20%), with enterohepatic recirculation.
