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 replacement therapy; binds to estrogen receptors (ERα and ERβ), modulating gene transcription and exerting effects on reproductive tissues, bone density, and cardiovascular system.
0.45 mg orally once daily; titrate up to 1.25 mg once daily based on symptoms. Maximum dose 1.25 mg/day.
1.25 mg orally once daily for 3 weeks, followed by a 1-week rest period; cyclic therapy.

Terminal elimination half-life is approximately 10-24 hours for conjugated estrogens; this long half-life allows for once-daily dosing and sustained estrogenic effects.
Terminal elimination half-life: 10–24 hours (mean ~15 h); clinically, steady-state achieved in 5–7 days
Primarily renal, with approximately 90% excreted in urine as glucuronide and sulfate conjugates; about 10% excreted in feces via bile.
Renal: 95% (as glucuronide and sulfate conjugates); biliary/fecal: ~5%
