title: Prospective, open-label, noncomparative study to assess cycle control, safety and acceptability of a new oral contraceptive containing gestodene 60 microg and ethinylestradiol 15 microg (Minesse).
abstract: OBJECTIVE
  A prospective, open-label, noncomparative, multicenter study was carried out in 163 women aged 18-39 (mean 25+/-5 years), who used an ultra-low-dose oral contraceptive pill (OCP) containing gestodene (GTD) 60 mug/ethinylestradiol (EE) 15 mug for 6 months. The objective of the study was to evaluate the acceptability, safety, bleeding patterns and premenstrual symptomatology in these women.
  
  
  METHODS
  Patients used the OCP from Days 1-24, followed by a 4-day pill-free interval from Days 25-28 of the menstrual cycle. Physical and gynecological examinations were carried out at baseline and after 3 and 6 months, at which time blood pressure, weight, hemoglobin, hematocrit, SGOT, SGPT and urinalysis were also assessed. The Moos Menstrual Distress Questionnaire (MDQ) was completed on three consecutive days (Days 25-27 of the cycle) at baseline and at the end of the third and sixth cycles. Patients kept a menstrual diary throughout the study.
  
  
  RESULTS
  A total of 146 women completed the study. Ten women discontinued because of adverse events and one undesired pregnancy occurred during treatment. No adverse metabolic effects were observed. The adverse event most frequently reported was breakthrough bleeding, which diminished, however, as the time of OC use increased. Cycle length and duration of bleeding decreased significantly with OC use (p<.01 and p<.05, respectively, after 6 months). Intensity of menstrual bleeding tended to decrease with OC use, but this difference was not statistically significant. Systolic and diastolic blood pressure were significantly lower after 6 months of OC use compared to baseline (p<.02). No alterations were recorded in body weight or laboratory evaluations. Statistically significant changes were found both in the total MDQ score and in several of the factors evaluated, and patients showed a statistically significant improvement in well-being with respect to premenstrual complaints and symptoms.
  
  
  CONCLUSIONS
  This OC regimen is safe, well-accepted and well-tolerated, affects menstrual patterns beneficially by reducing both the intensity and duration of bleeding, provides good cycle control and improves premenstrual symptomatology.
