[Experience in the photochemotherapy of psoriasis with rectal administration of the photosensitizer].

The authors compare the efficacy and tolerance of rectal (in suppositories) and oral administration of puvalen in 117 patients. The therapy has been highly effective in both the groups; clinical remission has been achieved in 78% of Group 1 patients and in 80% of Group 2 ones. Rectal puvalen has been better tolerated; the incidence rate of side effects has been 4 times lower.
