DIETHYLSTILBESTROL vs SYNTHETIC CONJUGATED ESTROGENS A
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.
Synthetic conjugated estrogens bind to estrogen receptors (ERα and ERβ) in target tissues, activating genomic and non-genomic signaling pathways that regulate gene transcription and cellular functions.
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.

Terminal elimination half-life is approximately 24 hours (range 20-30 hours) in adults; prolonged in hepatic impairment.

Terminal elimination half-life is 13-27 hours for estrone conjugates, allowing once-daily dosing.
Primarily renal (90% as glucuronide and sulfate conjugates), with less than 5% excreted unchanged in urine; biliary/fecal elimination accounts for about 10%.
Renal excretion of conjugated metabolites accounts for approximately 50-80% of elimination. Fecal/biliary excretion is minor (<10%).
