PURPOSE: The titled preparation that is formed by laminating a clear, pressure- sensitive adhesive layer containing psoralen or its derivative and an ultraviolet abosorber, thus being suitably used for treatimg dermatopathy with beams with reduced side-effects and simple aftertreatment on a clear support. n CONSTITUTION: The titled preparation is obtained by laminating a clear adhesive layer containing psoralen or its derivative such as 8-methoxypsoralen or 4,5'- trioxypsoralen and an ultraviolet absorber such as guaiazulene or camazulene on the transparent support layer. As the clear support, is mentioned, e.g., polypropylene which permeates UVA effective for treatment, preferably more than 50%. The adhesive is also desired to have transparency of the same level as in the support layer and such a cohesion as the adhesive layer is peeled off with no adhesive remaining on the skin after treatment, being, e.g., polymers from (meth)acrylic alkyl esters. n COPYRIGHT: (C)1985,JPO&Japio |
