ALESSE vs DIETHYLSTILBESTROL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of ethinyl estradiol and levonorgestrel suppresses gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus, inhibiting pituitary release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), thereby preventing ovulation. Additionally, it thickens cervical mucus, impeding sperm penetration, and alters endometrial receptivity.
Synthetic nonsteroidal estrogen that binds to estrogen receptors (ERα/ERβ), activating estrogen-responsive gene transcription, leading to proliferation of estrogen-sensitive tissues.
One tablet (ethinyl estradiol 20 mcg, levonorgestrel 0.1 mg) orally once daily at the same time each day for 21 days, followed by 7 days of placebo. For initiation, start on the first day of menstrual period or first Sunday after onset of menses.
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.

Levonorgestrel: terminal half-life ~17-20 hours (range 11-25 hr). Ethinyl estradiol: biphasic; terminal half-life ~13-27 hours (mean ~17 hr). Clinical context: steady-state achieved within 5-7 days. The half-life supports once-daily dosing with at least 24-hour contraceptive coverage.
Terminal elimination half-life is approximately 24 hours (range 20-30 hours) in adults; prolonged in hepatic impairment.
Renal: ethinyl estradiol (UE2) and levonorgestrel (LNG) metabolites primarily excreted in urine (UE2: ~40% as sulfate and glucuronide conjugates; LNG: ~25% as glucuronides). Fecal/biliary: ~40% (UE2) and ~45% (LNG) eliminated in feces via bile. Unchanged drug excretion is negligible.
Primarily renal (90% as glucuronide and sulfate conjugates), with less than 5% excreted unchanged in urine; biliary/fecal elimination accounts for about 10%.
