摘要:
The invention relates to the combination of polyvinyl acetate and water-insoluble, acid-insoluble, or alkali-insoluble polymers used for producing film coatings for forms of administration in which agents are released in a controlled manner, and methods for the production thereof. The controlled-release properties can be specifically adjusted by means of said combinations, resulting in films having excellent mechanical stability and storage stability. In particular, agents are released independent of the pH by means of the inventive forms of administration.
