Mechanism of action

Estradiol valerate is a natural estrogen that is metabolized to estradiol, while dienogest is a progestin with antimineralocorticoid activity. Together, they suppress the luteinizing hormone (LH) surge and follicle-stimulating hormone (FSH), preventing ovulation and thickening cervical mucus to provide contraceptive efficacy. The combination is designed to provide consistent hormone levels with a more physiologic estrogen profile.
