Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Estrogen replacement therapy; binds to estrogen receptors, activating gene transcription and exerting effects on reproductive tissues, bone, cardiovascular system, and CNS.
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.
0.45 mg orally once daily; titrate up to 1.25 mg once daily based on symptoms. Maximum dose 1.25 mg/day.
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.

Terminal elimination half-life is approximately 10-24 hours for conjugated estrogens; this long half-life allows for once-daily dosing and sustained estrogenic effects.
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.
Primarily renal, with approximately 90% excreted in urine as glucuronide and sulfate conjugates; about 10% excreted in feces via bile.
Primarily renal (metabolites, ~60-70%), with biliary/fecal elimination as minor routes (~20-30%). Unchanged drug is minimal in urine; extensive hepatic metabolism occurs.
