Ketoconazole Therapy for Women with Acne and/or Hirsutism

Institute of Reproductive Physiology and Pathology and Department of Evolutionary Experimental Biology (B.M), University of Bologna and Central Laboratory, S. Orsola-Malpighi Hospital (M.C) Bologna, Italy

The effects of ketoconazole, a synthetic imidazole derivate, were evaluated in 42 women affected by acne (17 cases) and/or hirsutism (36 cases) treated with 400 mg/day for3–6 months.

Androstenedione, total and free testosterone, 5adihydrotestosterone and dehydroepiandrosterone levels progressively dropped during treatment while 17 hydroxyprogesterone, estradiol, ACTH, cortisol, LH and FSH levels increased. Dehydroepiandrosterone sulfate decreased only towards the end of treatment, while estrone, sex hormone binding globulin, and PRL remained unchanged.

Daily mean ± SD rate of hair growth, measured by a special image analysis processor, decreased within 3 months of therapy from 0.258 ± 0.058 to 0.184 ± 0.039 mm/day (P < 0.02) and mean ± SD hair diameter from 0.123 ± 0.015 to 0.110 ± 0.013 mm (P < 0.05) together with decreasing hormone levels.

The therapeutic effects of ketoconazole on hirsutism was evident at 6 months in only 14 subjects, while no significant change in hirsutism score was recorded in 22 women who failed to complete the therapy. Acne improved in all cases. Several side effects and complications arose during treatment, such as headache, nausea, loss of scalp hair, hepatitis, and biochemical changes.

Even though ketoconazole improves hyperandrogenism, only selected patients are eligible for treatment as scrupulous monitoring is required.
