To investigate the clinical efficacy and safety of the finasteride (5 mg/day) plus flutamide (125 mg/day) combination therapy in unselected women with hirsutism, 44 women were involved in the study. The effects of such combination treatment have not been reported previously. The patients were assigned to 3 treatment groups: 14 patients (group 1) were treated with finasteride (5 mg per day), 16 patients (group 2) were treated with flutamide (125 mg per day), and 14 patients (group 3) were treated with finasteride (5 mg per day) plus flutamide (125 ring per day) for 12 months. Serum FSH, LH, estradiol, total testosterone, free testosterone, androstenedione, DHEAS, and SHBG were obtained. Hirsutism score was measured before and after treatment. Blood chemistry and side effects were evaluated during the study. The reductions in hirsutism score (% of the baseline) at 6 months were as follows: 24% for group 1, 35% for group 2, and 33% for group 3. Combination therapy resulted in (49%) similar improvement to flutamide alone (45%), but significantly (p<0.05) more efficacious improvement in hirsutism when compared to finasteride (32%) after 12 months of treatment. In conclusion, flutamide is more effective than finasteride and the combination of these two drugs is not better than flutamide alone, but better than finasteride in hirsute women.
