Clinical evaluation of two monthly injectable contraceptives and their effects on some metabolic parameters

One-hundred-and-thirty normally menstruating females were subgrouped equally and enrolled from the family planning clinic to study the clinical performance of the monthly injectable contraceptives medroxyprogesterone acetate 25 mg + estradiol cypionate 5 mg (Cycloprovera) and norethisterone enanthate 50 mg + estradiol valerate 5 mg (HRP-102) and their effects on some metabolic parameters. The contraceptive efficacy after 6 months of use for both drugs was 100%. No change in menstrual pattern occurred in 74% of Cycloprovera users and 67.3% of HRP-102 users. A statistically significant decrease (P less than 0.01) occurred in HDL-cholesterol and total serum protein values and a statistically significant increase (P less than 0.01) was observed in hematocrit value of Cycloprovera users only. Body weight and blood pressure values after 6 months of drug use showed no statistically significant changes in both groups. Also, no statistically significant changes were noticed in both groups for hemoglobin, post-prandial blood glucose, cholesterol, A/G ratio, SGPT and SGPT values following 6 months of injectable contraceptive use. None of the injectable users developed cervical dysplastic changes cytologically.
