Abstract
CDP-choline derivatives with macromolecules containing carboxy groups, such as polyacrylates, polymethacrylates, polyglutamates, polyaspartates and polymaleates, or copolymers of acrylic acid and methacrylic acid with methyl acrylate, methyl methacrylate or acrylamide. The polymeric derivatives of the invention gradually release CDP-choline, due to the action of enzymes present in the organism, thus exerting also a protective effect on the CDP-choline molecule.
