Evaluation of clinical and hormonal effects in hirsute women treated with ketoconazole.

Seven hirsute women were treated with 200 mg/12 h po of ketoconazole during 6 months. We evaluated clinical and hormonal effects during this period. Ketoconazole treatment decreased testosterone, androstenedione and dehydroepiandrosterone sulfate, while 17-alfahydroxyprogesterone increased. This finding suggests a steroidogenic blockade at the level of C17-20 lyase. We did not observe changes in LH, SHBG and cortisol values. In spite of this findings after 6 months treatment, hirsutism remained unmodified. We conclude that ketoconazole inhibits androgen synthesis in hirsute women, but the use of this drug as an alternative and effective treatment of hirsutism warrants further evaluation.
