What is the difference between Drosperinone and Loryna?

Drosperinone is the progesterone in Loryna. Loryna has BOTH drosperinone (progesterone) and ethinyl estradiol (estrogen). Birth control pills usually contain BOTH estrogen and a progesterone. And there are lots of different generic birth control with the same active ingredients at the same doses – for example Loryna = Yaz (lower dose estrogen though), Yasmin, Gianvi, Loryna, Ocella, Syeda, Vestura, Zarah.
