ABSTRACT:
Ad adhesive composition suitable for wound dressing and other medical applications comprising a mixture of polyisobutylene and a rubber polymer selected from the group consisting of random styrene butadiene copolymer (SBR) and halobutyl rubber so as to form a rubbery elastomer base matrix, and at least one hydrocolloid. The addition of the SBR or halobutyl rubber to the elastomer base offsets the possible degradation of the polyisobutylene upon sterilization, and therefore, helps to maintain the integrity of the composition. Water soluble hydrocolloid gums and water swellable cohesive strengthening agents are dispersed within the base matrix and may carry a pharmaceutical agent to be dispensed directly to a wound site.
