Detailed information:

Dienogest is a progestin, or a synthetic progestogen, of the 19-nortestosterone group.[4] It is available in combination with estradiol valerate (as Natazia, Qlaira) or ethinylestradiol (as Valette) for use as an oral contraceptive, and by itself (as Visanne, Dinagest) for the treatment of endometriosis in Europe, Australia, and Japan.[5] Although available in combination with estrogen as a contraceptive in the United States, dienogest is not available in this country by itself.[4] In addition to its progestogenic effects, dienogest has antiandrogenic activity, and as a result can improve androgenic symptoms such as acne.[3][6] It is a non-ethynylated progestin which is structurally related to testosterone.

Applications:

Endometriosis is a chronic, estrogen-dependent disease that affects approximately 10% of women of reproductive age, with a peak incidence in the age range of 25–30 years.1–3 Endometriosis is characterized by the formation of endometriotic lesions outside the uterus, including the ovaries and other pelvic structures. These lesions cause a chronic, inflammatory reaction, which can lead to the formation of scar tissue and adhesions.4 Women with endometriosis frequently experience symptoms of dysmenorrhea, premenstrual pain, dyspareunia, and chronic fatigue.5 Endometriosis can also interfere with functioning of the bowel or bladder, depending on the site where endometriotic lesions develop. Up to 50% of women with endometriosis experience infertility.6 However, the clinical presentations of endometriosis can vary widely, and many affected women are asymptomatic.7 No clear relationship exists between the extent of endometriotic lesions and a woman’s symptoms.

Dienogest is metabolized mainly by the cytochrome P450 enzyme CYP3A4,[1][5] and for this reason, inhibitors and inducers of CYP3A4 can alter the amount of exposure to dienogest when administered concomitantly with it.[5] (For a list of CYP3A4 inhibitors and inducers, see here.) The strong CYP3A4 inhibitors ketoconazole and erythromycin have been found to increase exposure to dienogest by up to 3-fold, whereas the strong CYP3A4 inducer rifampicin (rifampin) was found to decrease steady-state and area-under-curve concentrations of dienogest by 50% and 80%, respectively.

Users:

This combination hormone medication is used to prevent pregnancy. It contains 2 hormones: dienogest (a progestin) and estradiol valerate (an estrogen). It works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg.

Besides preventing pregnancy, birth control pills may make your periods more regular, decrease blood loss and painful periods, decrease your risk of ovarian cysts, and also treat acne.
