[Topical cimetidine treatment of acne].
We present first results of topically applied cimetidine in acne. Ten patients suffering from papulopustular and comedone acne administered 2% cimetidine in indifferent lotion on their face twice a day. Clinical controls were performed every two weeks; sebum was monthly determined. After treatment of 13 weeks on the average, the clinical success was generally good. Comedones responded best, followed by papules. Pustules were hardly reduced. There was no significant reduction of SER and the lipid fractions at the end of treatment. Low concentration or insufficient penetration might be possible explanations. The efficient reduction of comedones might be an antiandrogenic effect due to modulation of the keratinization in the follicle excretory duct. Immune-modulatory effects of cimetidine and effects on the skin vessels are other possible explanations for the clinical efficacy of topical application of cimetidine in acne.
