An open-label comparative study was conducted in nine centers in Brazil to evaluate the tolerability and cycle control of two low-dose oral contraceptives containing 20 mg ethynylestradiol/75 mg gestodene and 20 mg ethynylestradiol/150 mg desogestrel, during six treatment cycles. A total of 167 healthy sexually active women were enrolled (77 in the gestodene group and 90 in the desogestrel group) and 138 completed the six-cycle treatment period. A lipid and hemostatic profile was performed for a subgroup of first users. A total of 867 cycles were evaluated. Irregular bleeding did not occur in 95.4% of the cycles evaluated with gestodene and in 91.9% with desogestrel. Tolerability was good with both preparations but there was significantly more nausea in the desogestrel group. Cycle control was good with both preparations with a significantly lower incidence of irregular bleeding with gestodene when all cycles were considered. There were no clinically significant changes in the hemostatic profile. Lipid profile showed a trend to be more favorable after six cycles of treatment with both preparations. Women in the gestodene group did not present changes in the mean weight; in the desogestrel group there was a significant mean weight increase of 1 kg after six cycles of treatment. Compliance with treatment was good with both preparations. Results of this study demonstrated that low-dose preparations containing gestodene or desogestrel combined with 20 mg of ethynylestradiol are well-tolerated oral contraceptives that provide good cycle control.
