MULTICENTERED CLINICAL-STUDY OF THE METABOLIC EFFECT OF THE MONTHLY INJECTABLE CONTRACEPTIVE CONTAINING DIHYDROXYPROGESTERONE ACETOPHENIDE 150-MG + ESTRADIOL ENANTHATE 10-MG

The metabolic effect of the monthly injectable contraceptive containing dihydroxyprogesterone acetophenide (DHPA) 150 mg + estradiol enanthate (EEn) 10 mg was compared to that of other regularly used contraceptive methods (pills containing: ethinylestradiol (EE) 0.050 mg + levonorgestrel (LNG) 0.250 mg, EE 0.030 mg + LNG 0.150 mg; EE 0.030/0.040/0.030 mg + LNG 0.050/0.075/0.0125 mg; norethisterone enanthate (NEE) 200 mg i.m.; non-hormonal methods). Serum triglycerides, HDL/LDL-cholesterol, copper, ceruloplasmin, total and free cortisol, CBG, total and free testosterone and SHBG in chronic users were determined. A total of 237 women took part in this study. Taking users of non-hormonal methods as control, triglyceride levels were higher, and total and free testosterone levels were lower in women using DHPA 150 mg + EEn 10 mg and in those taking contraceptive pills (p < 0.05 - 0.01). Such modifications were slightly less in the group using the injectable. The effects of DHPA 150 mg + EEn 10 mg on HDL/LDL-cholesterol, copper, ceruloplasmin, CBG, total and free cortisol and SHBG were rare or non-existent. Nevertheless, the contraceptive pills (even the low-dose formulations) correlate with modifications of all those variables, which were highly significant in comparison with the injectable (p < 0.01) and with non-hormonal methods (p < 0.01); there were no differences between the last two methods. © 1990.
