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.
Estrogen receptor agonist; binds to estrogen receptors, modulating gene transcription and cellular proliferation in target tissues.
0.45 mg orally once daily; titrate up to 1.25 mg once daily based on symptoms. Maximum dose 1.25 mg/day.
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 10-24 hours for conjugated estrogens; this long half-life allows for once-daily dosing and sustained estrogenic effects.
Terminal elimination half-life is approximately 12-14 hours, supporting once-daily dosing in clinical use.
Primarily renal, with approximately 90% excreted in urine as glucuronide and sulfate conjugates; about 10% excreted in feces via bile.
Primarily renal; ~40% as unchanged drug and glucuronide conjugates. Biliary/fecal elimination is minor (~10-15%).
