Abstract
BACKGROUND
Increased sebaceous gland activity with seborrhea is one of the major pathogenetic factors in acne. Antiandrogen treatment targets the androgen-metabolizing follicular keratinocytes and the sebaceous gland leading to sebostasis, with a reduction of the sebum secretion rate of 12.5-65%. Antiandrogens can be classified based on their mechanism of action as androgen receptor blockers, inhibitors of circulating androgens by affecting ovarian function (oral contraceptives), inhibitors of circulating androgens by affecting the pituitary (gonadotropin-releasing hormone agonists and dopamine agonists in hyperprolactinemia), inhibitors of adrenal function, and inhibitors of peripheral androgen metabolism (5alpha-reductase inhibitors, inhibitors of other enzymes).
METHODS
All original and review publications on antiandrogen treatment of acne as monotherapy or in combination included in the MedLine system were extracted by using the terms "acne", "seborrhea", "polycystic ovary syndrome", "hyperandrog", and "treatment" and classified according to their level of evidence.
RESULTS
The combinations of cyproterone acetate (2 mg)/ethinyl estradiol (35 microg), drospirenone (3 mg)/ethinyl estradiol (30 microg), and desogestrel (25 microg)/ ethinyl estradiol (40 microg) for 1 week followed by desogestrel (125 microg)/ethinyl estradiol (30 microg) for 2 weeks showed the strongest anti-acne activity. Gestagens or estrogens as monotherapy, spironolactone, flutamide, gonadotropin-releasing hormone agonists, and inhibitors of peripheral androgen metabolism cannot be endorsed based on current knowledge. Low dose prednisolone is only effective in late-onset congenital adrenal hyperplasia and dopamine agonists only in hyperprolactinemia. Treatment with antiandrogens should only be considered if none of the contraindications exist.
CONCLUSION
Antiandrogen treatment should be limited to female patients with additional signs of peripheral hyperandrogenism or hyperandrogenemia. In addition, women with late-onset or recalcitrant acne who also desire contraception can be treated with antiandrogens as can those being treated with systemic isotretinoin. Antiandrogen treatment is not appropriate primary monotherapy for noninflammatory and mild inflammatory acne.
