ABSTRACT

O efeito metabólico do contraceptivo mensal injetável contendo acetofenido de dihidroxiprogesterona (DHPA) 150 mg + enantato de estradiol (Een) 10 mg foi comparado ao de outros métodos anticoncepcionais comumente utilizados (pílulas contendo: etinilestradiol (EEn) 0,050 mg + levonogestrel (LNG) 0,250 mg, EE 0,030 + LNG 0,150 mg; e EE 0,030/0,040/0,030mmg + LNG 0,050/0,075/0,0125 mg; enantato de noretisterona (NEE) 200 mg via i.m.; e métodos nao-hormonais. Foram determinados os triglicerídeos séricos, colesterol HDL/LDL, cobre, ceruloplasmina, cortisol total e livre, CBG e testosterona total e livre e SHBG de usu rios crônicas. Este estudo contou com a participaçäo do total de 237 mulheres. As usuárias de métodos nao-hormonais utilizadas como controle apresentaram níveis mais altos de triglicerídeos. Os níveis de testosterona total e livre foram mais baixos em mulheres que utilizavam DHPA 150 mg + Een 10 mg e nas que tomavam pílulas anticoncepcionais (p<0,05 - 0,01). Tais alteraçöes foram levemente menores no grupo que utilizou o injetável. Os efeitos do DHPA 150 mg + EEn 10 mg sobre o colesterol HDL/LDL, cobre, ceruloplasmina, CBG, cortisol total e livre e SHBG foram raros ou inexistentes. Entretanto, com as pílulas anticoncepcionais (mesmo as de formulaçäo de baixa dosagem) ocorreram alteraçöes em todas essas vari eis, que foram altamente significativas na comparaçäo com o método injetável (p< 0,01) e com os métodos nao-hormonais (p<0,01); näo houve diferenças entre estes dois últimos métodos. Os resultados sugerem que o efeito metabólico da injeçäo mensal i.m. de DHPA 150 mg + Een 10 mg näo é superior aos dos anticoncepcionais orais comumente utilizados. Estes resultados também nao sugerem que a dose contida nesse injetável seja excessiva. Nao há qualquer evidência de que ele produza efeito cumulativo no organismo. Esses achados devem ser levados em consideraçäo com relaçäo à segurança do uso a longo prazo desse injetável.

ABSTRACT

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 less than 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 less than 0.01) and with non-hormonal methods (p less than 0.01); there were no differences between the last two methods. The results suggest that the metabolic effect of DHPA 150 mg + EEn 10 mg is not higher than that of the commonly used oral contraceptives. On the other hand, they do not suggest that the dose contained in this injectable is exaggerated. There is no evidence that it produces accumulation of effects in the organism. These findings should be taken into account when referring to the long-term safety of this injectable.
