DIETHYLSTILBESTROL vs NORGESTREL AND ETHINYL ESTRADIOL
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.
Norgestrel is a progestogen that suppresses gonadotropin secretion, primarily LH, inhibiting ovulation and altering cervical mucus to impede sperm penetration. Ethinyl estradiol is an estrogen that stabilizes the endometrium and provides negative feedback on gonadotropin release, contributing to contraceptive efficacy.
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.
One tablet (0.3 mg norgestrel/0.03 mg ethinyl estradiol) orally once daily, taken at the same time each day.

Terminal elimination half-life is approximately 24 hours (range 20-30 hours) in adults; prolonged in hepatic impairment.
Norgestrel: terminal half-life ~45 hours (range 24–50 h), supporting once-daily dosing; Ethinyl estradiol: terminal half-life ~17 hours (range 10–24 h).
Primarily renal (90% as glucuronide and sulfate conjugates), with less than 5% excreted unchanged in urine; biliary/fecal elimination accounts for about 10%.
Norgestrel: 45% renal, 32% fecal as metabolites; Ethinyl estradiol: 40% renal, 60% fecal as glucuronide and sulfate conjugates.
