A three-year follow-up study of psoriasis patients treated with low dosages of etretinate orally and corticosteroids topically.

Etretinate 0.5 mg/kg body weight combined with 0.1% triamcinolone acetonide and 5% salicylic acid in an O/W cream gave more than 70% improvement in 62% of 75 patients. Of this satisfactorily improved group, at least 41% were still in the same condition after 3 years on a maintenance dose of, on average, 0.3 mg/kg body weight etretinate daily and 20 g weekly of a relatively strong corticosteroid cream. The side effects were acceptable and the convenience for the patients is great as compared with other treatment.
