More Information
Summary:The invention relates to a method for preventing the crystallization of a pharmaceutical in a polymer film, wherein the solvent-containing coating compound, which comprises a matrix-forming polymer or polymer mixture and at least one pharmaceutical and is spread to produce the polymer film, is temporarily dried at temperatures that is at least 10° C. above the melting temperature of the pharmaceutical contained in the coating compound. The maximum temperature is thus higher than that which is required for mere drying and obviates the need for an additional, time-consuming and expensive work step.
