An anti-infective medical article has chlorhexidine bulk distributed throughout a polyurethane base layer and may have a coating layer on the base layer. The coating layer may be chlorhexidine, an antibiotic, or an antithrombogenic agent permeated into the surface or it may be a polymeric surface layer having bulk distributed chlorhexidine laminated onto the base layer. The invention includes a method for preparing the article wherein a homogeneous melt of polymer and chlorhexidine is prepared by twin screw compounding and the melt is extruded to give a medical article having bulk distributed chlorhexidine. The article may then be laminated by dipping into a solution of chlorhexidine and a substantially hydrophilic polymer in a solvent.
