A new variation of plastic film occlusion is described, using a plastic tape into the adhesive side of which flurandrenolone has been incorporated. In a series of 10 patients with psoriasis, the efficacy of the tape is compared in a controlled manner with that of plastic film wrapping. The results with the tape are at least as good as, and probably better than, the results with the plastic film wrapping. The noteworthy finding is that all 10 of the patients treated preferred the tape to the plastic wrap because of the tape's greater convenience.
