Abstract
The invention relates to a dermal application system for aminolevulinic acid-derivatives, i.e. a pressure-sensitive matrix system containing a crystalline aminolevulinic acid derivative.
Claims7
A dermal application system, which is a self-adhesive matrix system, consisting of aminolaevulinic acid (ALA) salt crystals suspended in a polymer matrix, wherein the polymer matrix consists of polymers from the group consisting of acrylates, silicon polymers, and polyisobutylene, wherein a substantial amount of the crystals of the ALA salt have a mean diameter of 20 μm to 200 μm.
