Abstract
A medical device with an antimicrobial coating that is safe, effective, photostable and readily manufacturable can be produced by applying a composition to at least one body fluid-contacting surface of the device such that a solid coating is provided on that surface, the coating composition comprising an oligodynamic metal salt of a sulfonylurea, a polymeric material, at least one acid compound selected from the group consisting of a water-soluble carboxylic acid and water-insoluble carboxylic acid, and a carrier liquid in which foregoing components are soluble. The antimicrobial coating accommodates variation in the release of antimicrobial metal ions as a function of the intended use for a medical device to which the coating is applied.
