<p>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.</p><p>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. </p> |
