  Purpose

The objective of this study was to investigate the impact of the oral contraceptive YASMIN (containing: drospirenone 3 mg/ethinyl estradiol 30 mcg) in comparison with the oral contraceptive MICROGYNON (containing: levonorgestrel 150 mcg/ethinyl estradiol 30mcg) on factors of blood coagulation and fibrinolysis in female subjects

Primary Outcome Measures:
  • Pro-coagulatory parameters: Factor VIII (activity), Fibrinogen [ Time Frame: At baseline and after wash out (period 2); after 7 cycles of treatment in each of the two study periods ] [ Designated as safety issue: No ]
  • Anti-coagulatory parameters: Protein C (activity), Antithrombin III(activity), APC resistance (factor V mutation) [ Time Frame: At baseline and after wash out (period 2); after 7 cycles of treatment in each of the two study periods ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Rosing test: APC sensitivity ratio [ Time Frame: At baseline and after wash out (period 2); after 7 cycles of treatment in each of the two study periods ] [ Designated as safety issue: No ]
  • Pro-coagulatory parameters: Factor VIII (activity), Activation markers: D-dimer, Prothrombin fragment 1+2 [ Time Frame: At baseline and after wash out (period 2); after 7 cycles of treatment in each of the two study periods ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Arm 1 Drug: Yasmin (DRSP 3mg/EE 0.03 mg)

The study medication was packaged in 21-tablet blister packs. Each subject kit contained 7 blister packs plus 1 reserve blister pack.

Subjects randomly assigned to the treatment group received 21 consecutive days of hormonally active tablets (3mg DRSP/0.03 mgEE). In each treatment cycle 21 tablets (1 tablet daily) have to be taken in sequence, followed by a pill-free interval of 7 days. The treatment period was 7 cycles (28 days per cycle).

Active Comparator: Arm 2 Drug: Microgynon (LNG 0.15 mg/EE 0.03 mg)

The study medication was packaged in 21-tablet blister packs. Each subject kit contained 7 blister packs plus 1 reserve blister pack.

Subjects randomly assigned to the treatment group received 21 consecutive days of hormonally active tablets (LNG 0.15 mg/EE 0.03 mg). In each treatment cycle 21 tablets (1 tablet daily) have to be taken in sequence, followed by a pill-free interval of 7 days. The treatment period was 7 cycles (28 days per cycle).

Criteria

Inclusion Criteria:

  • Clinically normal safety laboratory results

Exclusion Criteria:

  • Standard contraindications for use of combined oral contraceptives (class label).
  • Including:
  • Presence or history of thromboembolic process in veins (such as deep venous thrombosis, pulmonary embolism) or arteries (e.g., stroke, myocardial infarction) or a known genetic component (homozygous), venous thromboembolic event in a close relative (parents or siblings) at younger age (</= 40 years).
  • Acute and chronic severe liver dysfunction or disease. There should be an interval of at least 6 months between the subsidence of a viral hepatitis (normalization of the liver parameters) and the start of the study medication.
  • Use of preparations where experience shows affect on the activity of hepatic enzymes.
