Abstract
Improved antimicrobial adhesive copolymer compositions for wound closure or surgical-site closure are provided. The antimicrobial adhesive copolymer compositions comprise cyanoacrylate-based tissue adhesive monomers and long-chain quaternary ammonium compounds (QUATs), or long-chain quaternary phosphonium compounds (QUPTs). The antimicrobial adhesive copolymer compositions offer advantages in wound closure or surgical-site closure with bactericidal and bacteriostatic effects on Gram-positive and Gram-negative organisms.
Claims10
An antimicrobial adhesive copolymer composition for wound closure, comprising:
- a cyanoacrylate component;
- and
- a charged quaternary ammonium component or a charged quaternary phosphonium component, wherein the charged quaternary ammonium component or the charged quaternary phosphonium component comprises at least one reactive alkene group, and alkyl group of the charged quaternary ammonium component or charged quaternary phosphonium component is CnH2n+1, where n ranges from 4 to 18.
