[One-hour-treatment of psoriasis with anthralin and UV-light (author's transl)].

A total of 66 patients with psoriasis was treated with one percent anthralin for one hour (one-hour-treatment) and UV-light. 17 out of 26 out-patients treated with anthralin and UVB showed a good response. In 40 in-patients the one hour regimen was administered in combination with UVA or UVB, in part in right-left side comparison in order to evaluate whether anthralin with UV-light is more effective than anthralin alone. Within six weeks remission was obtained with anthralin alone as well as with combined treatment with anthralin and UVA or UVB. In right-left side comparison UV-light had no significant additional effect in this regimen. The one-hour-treatment was effective but did not seem to be superior to the conventional therapy with anthralin in in-patients. However, the one-hour-treatment is advantageous and convenient for out-patients.
