title: Clinical and metabolic study of a new pill containing 20 mcg ethinylestradiol plus 0.150 mg desogestrel.
abstract: The clinical and metabolic effects of a short-term treatment with a combination contraceptive pill containing 0.150 mg desogestrel and 20 mcg ethinylestradiol were evaluated in a group of 17 healthy women. In spite of the low estrogen content, the pill exerted a good cycle control and the incidence of irregular bleedings was low. The minor side effects commonly associated with oral contraceptive (OC) use rarely occurred, and an improvement of premenstrual symptoms was reported during pill intake. As for the different biochemical parameters tested, the formulation induced a significant increase of fibrinopeptide A (FPA) plasma levels. However, the resulting increase of peptide was lower than that induced by pills containing 30 mcg ethinylestradiol. No significant modifications of plasma total cholesterol (T-CH) and low-density lipoprotein cholesterol (LDL-CH) were observed, while triglycerides (TG), high-density lipoprotein cholesterol (HDL-CH) concentrations and the HDL-CH/LDL-CH ratio significantly increased. A significant increase of apolipoproteins AI (Apo AI) and apolipoproteins AII (Apo AII) concentrations was also observed. Moreover, the pill did not alter fasting insulin and glucose levels and their response to an oral glucose tolerance test (OGTT). It may be concluded that this new formulation can be considered acceptable for clinical use, mainly in consideration of the minor or no changes in the biochemical parameters regarded as risk factors for venous and arterial diseases.
