Yaz (drospirenone + synthetic ethinyl estradiol) is manufactured by Bayer HealthCare Pharmaceuticals Inc. The drug was approved by the FDA on March 10, 2006. Bayer advertised 'Yaz' as a new generation pill for birth control that could not only prevent pregnancy but also help women lose weight, cure acne, and help with premenstrual moodiness.
Yaz is a birth control pill used to avoid pregnancy. It is also used to treat premenstrual dysphoric disorder (PMDD) and certain types of acne. Yaz contains a combination of a new generation of synthetic progesterone called 'drospirenone' (3 mg) and synthetic ethinyl estradiol (0.02 mg). Yaz acts by preventing ovulation, thickening of mucus in the cervix, and also by changing the uterine lining, thereby, preventing pregnancies. Yaz strip contains 24 active pills that include the hormones and four inactive pills. Most birth control pills include seven inactive pills; thus, Yaz gives the patient an increased dose of hormones throughout the month.
The new generation synthetic progesterone 'drospirenone,' which is similar in chemical content to diuretic Spironolactone, has been associated with an increase in blood clots, pulmonary embolisms, heart attacks, strokes, gallbladder disease, and elevated potassium levels. Drospirenone also has anti-androgenic properties that work against testosterone and other hormones.
Some of the other brand names with similar hormonal compositions by Bayer HealthCare Pharmaceuticals Inc. are Yasmin, Beyaz, Safyral, and Ocella.
