Summary
In an open-design study 1α-hydroxyvitamin D3 was administered orally to 17 patiens with psoriasis vulgaris at a dose of 1.0 μg/day for 6 months. More than moderate improvement was observed in 13 (76 %) of the 17 patients from 2.7±0.6 months (mean±SD) after the start of treatment. No side effects of the treatment were observed. The mechanism of the effect of 1α-hydroxyvitamin D3 requires study, but these data suggest that its oral administration is effective for treatment of psoriasis vulgaris.
