J Clin Endocrinol metab. 1999 Apr;84(4):1304-10. A prospective randomized trial comparing low dose flutamide, finasteride, ketoconazole, and cyproterone acetate-estrogen regimens in the treatment of hirsutism. Venturoli S, Reproductive Medicine Unit, Institute of Obstetrics and Gynecology, University of Bologna, Italy. Sixty-six hirsute women were randomized and treated with 1) flutamide (n = 15), 250 mg/day; 2) finasteride (n = 15), 5 mg/day; 3) ketoconazole (n = 16), 300 mg/day; and 4) ethinyl estradiol (EE)-cyproterone acetate (CPA; n = 20), 0.01 mg EE/day for the first week, 0.02 mg EE/day for the second week, and 0.01 mg EE/day for the third week, followed by a pause of 7 days, then 12.5 mg CPA/day added during the first 10 days of every month for 12 months. Hirsutism was evaluated by the Ferriman-Gallwey score, and hair diameter and hair growth rate were determined by a special image analysis processor in basal conditions and after 90, 180, 270, and 360 days of treatment. All treatments produced a significant decrease in the hirsutism score, hair diameter, and daily hair growth rate: flutamide, -55 +/- 13%, -21 +/- 14%, and -37 +/- 18%; finasteride, -44 +/- 13%, -16 +/- 12%, and -27 +/- 14%; ketoconazole, -53 +/- 18%, -14 +/- 12%, and -30 +/- 21%; and EE-CPA, -60 +/- 18%, -20 +/- 11%, and -28 +/- 21%. Some differences existed among treatments with regard to effectiveness; EE-CPA and flutamide seem to be the most efficacious in improving hirsutism. For the hirsutism score, a greater decrease was seen with EE-CPA (-60 +/- 18%) than with finasteride (-44 +/- 13%; P<0.01) and a greater decrease was seen with flutamide (-58 +/- 18%) than with finasteride (-44 +/- 13%; P<0.05). Flutamide is the fastest in decreasing hair diameter; EE-CPA is the fastest in slowing down hair growth, even though at the end of the treatment there was a significant difference between flutamide and finasteride only (-41 +/- 18% vs. -27 +/- 14%; P<0.05). Flutamide, ketoconazole, and EE-CPA induced a significant decrease in total and free testosterone, 5alpha-dihydrotestosterone, dehydroepiandrosterone, dehydroepiandrosterone sulfate, and androstenedione plasma levels. During the EE-CPA treatment, gonadotropins were suppressed, and the sex hormone-binding globulin level increased. Finasteride induced a decrease in dehydroepiandrosterone sulfate and 5alpha-dihydrotestosterone and an increase in testosterone levels. Very few side effects were observed during treatment with low doses of flutamide, EE-CPA, and particularly finasteride. Flutamide induced a decrease whereas EE-CPA induced an increase in triglycerides and cholesterol, showing higher values within the normal range. Ketoconazole induced several side effects and complications, and several people dropped out of the study. Despite different modalities of action and significantly different effects on androgen levels, low doses of flutamide, finasteride, and EE-CPA constitute very satisfactory alternative therapeutic regimens in the treatment of hirsutism.
