gestodene and Nausea

The aim of this study was to compare contraceptive reliability, cycle control and tolerance of an oral contraceptive containing 20 micrograms ethinylestradiol and 75 micrograms gestodene, with a reference preparation containing the same dose of estrogen combined with 150 micrograms desogestrel. This article presents interim data from centers in France and Austria, involving a total of 479 women and 4,991 cycles. Contraceptive reliability was good with both preparations. Two pregnancies occurred in the gestodene group, but neither were due to method failure. In the desogestrel group there were also two pregnancies, of which one was due to method failure. With respect to cycle control, there is a trend towards a lower incidence of intermenstrual bleeding in the gestodene group. The incidence of spotting (scanty bleeding) during the important first three cycles was 3.5% lower in the gestodene group, and over the first six cycles, it was 7.6% lower. Amenorrhea was similar in both groups, but the incidence of dysmenorrhea was significantly lower in the gestodene group (p=0.001). Adverse events were similar in both groups, with headache, breast tension and nausea the most frequently reported symptoms. Body weight remained relatively constant during treatment in both groups, and no hypertension was reported for any woman during the course of the study. In each treatment group, 19 women discontinued because of adverse events. It is concluded that both preparation are reliable and well tolerated oral contraceptives are reliable and well tolerated oral contraceptives; however, there is a more favourable effect on dysmenorrhea by the gestodene formulation.

The contraceptive efficacy, cycle control, safety, and subject acceptance of the new contraceptive (OC) preparations containing gestodene (GTD) plus ethinyl estradiol (EE) are being compared with the combination containing desogestrel (DSG) plus EE in a randomized, open-label outpatient study. Interim data from six cycles of this ongoing study were obtained for 378 women receiving 75 micrograms GTD + 30 micrograms EE per day and 384 women receiving 150 micrograms DSG + 30 micrograms EE per day. Each group received OCs for 21 days per cycle. There were no pregnancies in subjects receiving either OC during 1,658 cycles of GTD + EE or 1,707 cycles of DSG + EE use. The continuation rates were similar in the two groups, and no major differences in type or incidence of side effects were observed. There were also no clinically significant changes in blood pressure or body weight in either group. Slightly better cycle control was observed for subjects taking GTD + EE, since the incidence of spotting and breakthrough bleeding was slightly greater for women taking DSG + EE. The incidence of amenorrhea (missed periods) tended to be lower for the subjects taking the GTD-containing preparation: 7 (0.5%) cycles compared with 12 (0.9%) DSG + EE cycles. The GTD + EE-treated subjects also had a lighter menstrual flow. Fewer subjects taking GTD + EE withdrew because of side effects typically associated with OCs. The data from this study indicate that the new combination of GTD + EE provides safe and effective oral contraception, with good tolerance and cycle control.

The purpose of this study was to compare cycle control, efficacy and side effects of an oral contraceptive containing 20 microg ethinylestradiol and 75 microg gestodene, with a reference preparation containing 30 microg ethinylestradiol combined with 75 microg gestodene. From the study, it was demonstrated that the two regimens had no difference in cycle control, efficacy, and side effects. The occurrence of spotting and breakthrough bleeding was low and was not different between these two preparations. The most common adverse events in both treatment groups were nausea, vomiting, dizziness, and chloasma. There were no statistically significant change in body weight and blood pressure in both groups at the end of study. It is concluded that both preparations are good cycle control, reliable and low side effects oral contraceptives.
