Clinical and metabolic effects of a pill containing 30 mcg ethinylestradiol plus 75 mcg gestodene.
The clinical and metabolic effects of a short-term treatment with a combination contraceptive pill containing 30 mcg ethinylestradiol and 75 mcg gestodene were evaluated in a group of 31 healthy women. The pill exerted good cycle control and the incidence of irregular bleeding was low. Side effects rarely occurred, and an improvement in premenstrual symptoms was reported during pill intake. Among the different biochemical parameters tested to monitor the coagulatory system, the only modification observed was an increase of fibrinopeptide A plasma levels, confirming that low-dose pills have less effects on the haemostatic system than oral contraceptives with a higher estrogen content. No significant modification in plasma total cholesterol, triglycerides, high density lipoprotein-cholesterol (HDL-CH), HDL2-CH, nor low density lipoprotein-cholesterol were observed. HDL3-CH levels were significantly increased. Moreover, the pill did not significantly alter the fasting insulin and glucose levels nor their response to an oral glucose tolerance test. It may be suggested that this new formulation has high efficacy and clinical acceptability, primarily due to the total absence of any adverse metabolic effect.
