Yes. There are many combined pills similar to Dronis 30 that contain the same active ingredients (drospirenone and ethinyl estradiol) in similar strengths like Yasmin, Crisanta, Yanci and Janya. While the active ingredients in all these pills are the same, the only difference is that each of them are manufactured by different companies and can vary in price.
There are other combined pills that contain a combination of ethinyl estradiol and levonorgestrel. Although both drospirenone and levonorgestrel are synthetic versions of the progesterone hormone, levonorgestrel has been used in combined pills for much longer than drospirenone which is a newer progestin.
