Inclusion Criteria

1. written IC
2. healthy females of childbearing potential 18-40 years + in good health as determined by past medical history, physical examination, vital signs, ECG, 24 h Holter and lab tests, PAP smear, gynecological exam. and transvaginal ultrasound before dosing in period 1
3. Stable regimen of monophasic OC containing EE (30 microgram)/LVG (150 microgram) as for at least three cycles prior to dosing in period 1 and willing to undergo synchronization of at least one cycle until day -7. Any subject not taking any OC or taking another brand of monophasic OC should be willing to take monophasic OC containing EE 30 microgram and LVG 150 microgram for at least three cycles during synchronization until day -7.Willing to continue OC until at least 30 d after study completion
4. negative pregnancy test results at screening and baseline 1
5. willing to use additional, non-hormonal contraception from screening until 30 days after study completion.
6. willing to undergo genotyping screening prior to baseline 1, must be CYP2C9 WT
7. willing to abstain from strenuous and/or unaccustomed physical exercise for 7 d before dosing with OC at D1 until after study completion evaluation. At screening and baseline 1, vital signs (BP and pulse rate) will be assessed in supine position after the subject has rested for at least 3 min, and again when required after 3 min in the standing pos. Investigator can be guided by: oral body temp 35-37.5°C, systolic BP 90-140 mm Hg, diastolic BP 50-90 mm Hg, pulse rate 50-90 bpm. BP and pulse after 3 min standing no more than 20 mm Hg drop systolic or 10 mm Hg drop diastolic and increase in heart rate >20 bpm (compared to sitting) associated with clin. manifestation of postural hypotension.
8. weight of at least 50 kg, BMI in the range of 18-30 kg/m2
