Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic nonsteroidal estrogen; binds to estrogen receptors (ERα and ERβ), activating estrogen-responsive gene transcription, leading to estrogenic effects on reproductive tissues, bone, and other targets.
Estrogen replacement therapy; binds to estrogen receptors (ERα and ERβ), modulating gene transcription and exerting effects on reproductive tissues, bone density, and cardiovascular system.
12-25 mg orally once daily for palliation of advanced breast cancer in postmenopausal women; may increase to 25 mg twice daily if no response after 1 month. For prostate cancer, 12-25 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 10-12 hours, but due to enterohepatic recirculation and accumulation in adipose tissue, effective half-life during chronic dosing may extend to several days.
Terminal elimination half-life: 10–24 hours (mean ~15 h); clinically, steady-state achieved in 5–7 days
Primarily renal (metabolites, ~60-70%), with biliary/fecal elimination as minor routes (~20-30%). Unchanged drug is minimal in urine; extensive hepatic metabolism occurs.
Renal: 95% (as glucuronide and sulfate conjugates); biliary/fecal: ~5%
