Both Daing-35 and Eusemide are birth control pills, the difference between them is: 1. the content of estrogen is different, Daing-35 contains 35μg of estrogen and Eusemide contains 30μg. 2. the progestin contained is different, Daing-35 contains a progestin called cyproterone and Eusemide contains a progestin called drospirenone. Cipro progesterone has the effect of reducing androgens in the body, and can compete with androgens and bind to receptors, thus blocking the peripheral effects of androgens. Therefore, Daimler-35 is mostly used for polycystic ovary syndrome, as well as for patients with relatively high androgen levels, and Eusebio is used for female contraception.
