Contraception

Investigation of bioequivalence of ethinylestradiol (EE) and drospirenone (DRSP) in two different tablet formulations: Yasmin and Yasmin + levomefolate calcium (Metafolin) & L-5-MTHF in two different tablet formulations: levomefolate calcium (Metafolin) and Yasmin + levomefolate calcium (Metafolin)

Trial purpose

The purpose of this study is to examine and compare the uptake of Yasmin (oral contraceptive containing drospirenone and ethinylestradiol) with or without levomefolate calcium (Metafolin, a registered vitamin supplement) in the body and to examine and compare the uptake of levomefolate calcium with or without Yasmin in the body, in healthy volunteers not using hormonal contraception.
