摘要：
A multistage preparation for contraception based on a combination of natural estrogen and synthetic gestogen is described. The preferred preparation contains estradiol valerate as the natural estrogen and dienogest or drospirenone as the synthetic gestogen. In comparison to conventional multistage preparations the multistage preparation according to the invention has a higher contraceptive reliability over the entire cycle, improved cyclic bleeding behavior and minimizes or prevents side effects, such as breast tension, headaches, depressive moods and libido changes.
