DIETHYLSTILBESTROL vs ESTROPIPATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic nonsteroidal estrogen that binds to estrogen receptors (ERα/ERβ), activating estrogen-responsive gene transcription, leading to proliferation of estrogen-sensitive tissues.
Estropipate is a prodrug of estrone, converted to estradiol, which binds to estrogen receptors (ERα and ERβ), activating transcription of estrogen-responsive genes involved in growth, differentiation, and function of female reproductive tissues.
0.5-2 mg orally once daily for palliative treatment of advanced prostate cancer; 5-15 mg orally once daily for prevention of postpartum breast engorgement.
Oral: 1.25 mg to 2.5 mg daily for 3 weeks, followed by 1 week off; or continuous daily dosing of 0.625 mg to 1.25 mg.

Terminal elimination half-life is approximately 24 hours (range 20-30 hours) in adults; prolonged in hepatic impairment.
Terminal elimination half-life of estradiol: ~12-14 hours (range 10-16 h); estrone: ~10-12 h; estrone sulfate: ~10-12 h. Clinical context: Steady-state achieved within 5-7 days; dosing interval typically once daily.
Primarily renal (90% as glucuronide and sulfate conjugates), with less than 5% excreted unchanged in urine; biliary/fecal elimination accounts for about 10%.
Renal: 50-80% as conjugated and unconjugated estrogens (primarily estrone sulfate and estradiol glucuronide); biliary/fecal: 20-30% as glucuronide conjugates undergoing enterohepatic recirculation.
