    Abstract:
    In this open-label, randomized study we compared the influence of a new oral contraceptive containing 30 microg ethinylestradiol and 3 mg drospirenone (EE + DRSP = Yasmin), with a reference preparation containing 30 microg ethinylestradiol and 150 microg desogestrel (EE + DSG = Marvelon) on the lipid profile. The primary target variables were total high-density lipoprotein (HDL) cholesterol, HDL2 cholesterol and low-density lipoprotein (LDL) cholesterol. These and additional lipid and lipoprotein fractions were measured at baseline and in the 3rd, 6th and 13th treatment cycles in a total of 50 volunteers, and also assessed after density gradient ultracentrifugation. A slight increase in mean total HDL cholesterol vs. baseline was found for the DRSP group (+12.8%) and the DSG group (+11.8%) after 13 treatment cycles. HDL2 cholesterol did not change remarkably in both groups. The mean LDL cholesterol values increased by 10.6% vs. baseline in the DSG group and remained nearly stable in the DRSP group (+1.8%). All measured values remained within the reference ranges. No statistically significant differences were found between the two treatment groups for those primary endpoints. A slight rise in mean total cholesterol was found for all cycles after the initiation of treatment. The mean increase after 1 year of treatment was approximately 8% in both treatment groups. Mean triglyceride levels increased for both treatment groups without leaving the reference range. The increase for total triglycerides was +73.6 % in the DRSP group and +61.3% in DSG group. For total phospholipids, an increase of +13.6% (DRSP) and +18.5% (DSG) over 13 cycles was measured. The apolipoproteins Apo A-I, Apo A-II and Apo B increased slightly more during DRSP treatment than during DSG treatment. The reduction of Apo E was similar in both groups. Lipoprotein (a) remained stable in the DRSP group, whereas it increased by +10.8% in the DSG group. In conclusion, the combined low-dose oral contraceptive Yasmin, with 30 microg ethinylestradiol and 3 mg of the novel progestogen drospirenone, as well as the reference preparation, had little impact on the lipid profile. While both preparations displayed a favorable lipid profile with increased total HDL cholesterol, the antiandrogenic or missing androgenic activity of Yasmin may be regarded as responsible for the stable LDL cholesterol levels. As a result, the ratio of total HDL:LDL was increased, a pattern that is usually considered clinically beneficial with respect to cardiovascular disease risk.
