Yaz (drospirenone+synthetic ethinyl estradiol) is manufactured by Bayer HealthCare Pharmaceuticals Inc. The drug approved by the FDA on March 16, 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 the 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 the mucus in the cervix and also by changing the uterine lining, thereby preventing pregnancies. Yaz 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 through 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.
