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.

Mean Maximum Concentration (Cmax) of EE Incl. Bioequivalence (BE) Evaluation
Cmax refers to the highest measured drug concentration which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample.
Time frame: up to 96 hours after administration
Mean Area Under the Concentration-time Curve From Administration to the Last Measurement [AUC(0-tlast)] of EE 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 96 hours after administration
Mean Maximum Concentration (Cmax) of DRSP Incl. Bioequivalence (BE) Evaluation
Cmax refers to the highest measured drug concentration 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
Mean Area Under the Concentration-time Curve (AUC) 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
Mean Maximum Concentration (Cmax) of L-5-methyl-THF (Baseline Corrected) Incl. Bioequivalence (BE) Evaluation
The baseline corrected Cmax is a measure of the highest measured drug concentration provided solely by the treatment after subtracting endogenous L-5-methyl-THF level. It is obtained by collecting a series of blood samples, measuring the concentrations of L-5-methyl-THF in each sample and by subtracting the pre-treatment concentration.
Time frame: up to 12 hours after administration
Mean Area Under the Concentration-time Curve From Administration to the Last Measurement [AUC(0-tlast)] of L-5-methyl-THF (Baseline Corrected) Incl. Bioequivalence (BE) Evaluation
The baseline corrected AUC is a measure of the systemic drug exposure provided by the treatment excluding the endogenous L-5-methyl-THF level. It is obtained by collecting a series of blood samples, measuring the concentrations of L-5-methyl-THF in each sample and by subtracting the pre-treatment concentration.
Time frame: up to 12 hours after administration
Mean Maximum Concentration (Cmax) of L-5-methyl-THF (Baseline Uncorrected) Incl. Bioequivalence (BE) Evaluation
The baseline uncorrected Cmax is a measure of the highest measured drug concentration including the endogenous L-5-methyl-THF level. It is obtained by collecting a series of blood samples and measuring the concentrations of L-5-methyl-THF in each sample.
Time frame: up to 12 hours after administration
Mean Area Under the Concentration-time Curve From Administration to the Last Measurement [AUC(0-tlast)] of L-5-methyl-THF (Baseline Uncorrected) Incl. Bioequivalence (BE) Evaluation
The baseline uncorrected AUC is a measure of the systemic drug exposure provided by the treatment including the endogenous L-5-methyl-THF level. It is obtained by collecting a series of blood samples and measuring the concentrations of L-5-methyl-THF in each sample.
Time frame: up to 12 hours after administration
Time to Reach Maximum Concentration (Tmax) of EE
Tmax refers to the time after dosing when a drug attains its highest measurable concentration (Cmax). It is obtained by collecting a series of blood samples at various times after dosing, and measuring them for drug content
Time frame: up to 96 hours after administration
Mean Area Under the Concentration-time Curve From Administration up to 72h AUC(0-72h) of DRSP
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 72 hours after administration
Time to Reach Maximum Concentration (Tmax) of DRSP
Tmax refers to the time after dosing when a drug attains its highest measurable concentration (Cmax). It is obtained by collecting a series of blood samples at various times after dosing, and measuring them for drug content
Time frame: up to 168 hours after administration
Time to Reach Maximum Concentration (Tmax) of L-5-methyl-THF
Tmax refers to the time after dosing when a drug attains its highest measurable concentration (Cmax). It is obtained by collecting a series of blood samples at various times after dosing, and measuring them for drug content
Time frame: up to 12 hours after administration
