Trial Condition(s):
Investigation of bioequivalence of ethinylestradiol (EE) and drospirenone (DRSP) in two different tablet formulations: YAZ and YAZ + levomefolate calcium (Metafolin) & L-5-MTHF in two different tablet formulations: levomefolate calcium (Metafolin) and YAZ + levomefolate calcium (Metafolin)
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
- Healthy female volunteer - Age: 18 – 38 years inclusive - Body mass index (BMI)1: ≥ 19 and < 28 kg/m² - Regular cyclic menstrual periods at screening OR when using combined oral contraceptives during the recruitment period reporting of natural cyclic menstrual periods prior to their use - Willingness to use non-hormonal methods of contraception during the complete trial OR previous tubal ligation
- incompletely cured pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, excretion and effect of the study drugs will not be normal - known or suspected sex-steroid influenced malignancies - endometrial hyperplasia; genital bleeding of unknown origin; uterus myomatosus - known or suspected tumors of the liver and pituitary - presence or history of severe hepatic disease as long as liver function values have not returned to normal - severe renal insufficiency or acute renal failure - thrombophlebitis, venous / arterial thromboembolic diseases; presence or history of prodromi of a thrombosis - other conditions that increase susceptibility to thromboembolic diseases - known neuropsychiatric diseases, especially known or suspected epilepsy, and/ or deficient status of folate or vitamin B12 - use of any other medication within 2 cycles before first study drug administration which could affect the study aim - use of potassium sparing drugs; use of folic acid containing supplements or medicines or use of any medication within 2 cycles before first study drug administration known to interfere with folate metabolism - inadequate folate and/or Vitamin B12 status, clinically relevant deviations in red cell folate concentrations
