NATURAL ESTROGENIC SUBSTANCE-ESTRONE vs OGEN 1.25
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Estrone binds to and activates estrogen receptors (ERα and ERβ), leading to modulation of gene transcription and subsequent estrogenic effects on target tissues.
Estrogen replacement therapy; binds to estrogen receptors (ERα and ERβ), modulating gene transcription and exerting effects on reproductive tissues, bone density, and cardiovascular system.
0.1 to 0.5 mg intramuscularly 2 to 3 times per week for estrogen replacement therapy
1.25 mg orally once daily for 3 weeks, followed by a 1-week rest period; cyclic therapy.

Terminal half-life: 24-48 hours (prolonged due to enterohepatic recirculation and tissue distribution).
Terminal elimination half-life: 10–24 hours (mean ~15 h); clinically, steady-state achieved in 5–7 days
Renal: ~50% (as glucuronide and sulfate conjugates), Biliary/Fecal: ~50% (enterohepatic recirculation).
Renal: 95% (as glucuronide and sulfate conjugates); biliary/fecal: ~5%
