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; binds to estrogen receptors (ERα and ERβ), modulating gene transcription and exerting effects on reproductive tissues, bone density, and cardiovascular system.
1 to 2 mg orally once daily; for testosterone replacement in adult males, 2 to 4 mg orally once daily.
1.25 mg orally once daily for 3 weeks, followed by a 1-week rest period; cyclic therapy.

Terminal elimination half-life is approximately 12-14 hours, supporting once-daily dosing in clinical use.
Terminal elimination half-life: 10–24 hours (mean ~15 h); clinically, steady-state achieved in 5–7 days
Primarily renal; ~40% as unchanged drug and glucuronide conjugates. Biliary/fecal elimination is minor (~10-15%).
Renal: 95% (as glucuronide and sulfate conjugates); biliary/fecal: ~5%
