Abstract
The paper evaluates powder-like hydrogels based on polymers and copoly mers of 2-hydroxyethylmethacrylate (HEMA) and methacrylic acid (MAA) a s potential pharmaceutical adjuvants. The possibility of use of these substances in the form of composite materials with silicone rubber as matrices for transdermal therapeutic systems was studied. The rate of release of nitroglycerin from the matrices at discontinuous sink condi tions was measured and evaluated using a Tornquist hyperbolic function . The results show that the HEMA-MAA copolymers are prospective adjuva nts for use in transdermal therapeutic systems.
