The purpose of this study is examine and compare the uptake of YAZ (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 YAZ in the body, in healthy volunteers not using hormonal contraception

Outcome results

Mean Area Under the Concentration-time Curve From Administration to the Last Measurement [AUC(0-tlast)] of DRSP Incl. Bioequivalence (BE) Evaluation

The AUC is a measure of systemic drug exposure, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample

Time frame: up to 168 hours after administration

Population: Note that not all samples were evaluable for each outcome measure. Therefore the number of participants analyzed not necessarily matches the number of completers.
