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 receptor agonist; binds to estrogen receptors, modulating gene transcription and cellular proliferation in target tissues.
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 to 2 mg orally once daily; for testosterone replacement in adult males, 2 to 4 mg orally once daily.

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 is approximately 12-14 hours, supporting once-daily dosing in clinical use.
Primarily renal (metabolites, ~60-70%), with biliary/fecal elimination as minor routes (~20-30%). Unchanged drug is minimal in urine; extensive hepatic metabolism occurs.
Primarily renal; ~40% as unchanged drug and glucuronide conjugates. Biliary/fecal elimination is minor (~10-15%).
