ESTRADIOL VALERATE AND DIENOGEST

AbsorptionAfter oral administration of estradiol valerate, cleavage to 17β-estradiol and valeric acid takes place during absorption by the intestinal mucosa or in the course of the first liver passage. This gives rise to estradiol and its metabolites, estrone and other metabolites. Maximum serum estradiol concentrations of 73.3 pg/mL are reached at a median of approximately 6 hours (range: 1.5–12 hours) and the area under the estradiol concentration curve [AUC(0–24h)] was 1301 pg·h/mL after sin...

14.1 Oral Contraceptive Clinical Trials The study conducted in North America (U.S. and Canada) was a multicenter, open-label, single-arm, unintended pregnancy study.
