  • Publication number: 20190133126
    Abstract: Disclosed herein are compositions useful for coating medical devices which have antimicrobial (anti-infective) qualities and which are simple to manufacture and cost-effective, and therefore suitable for global use, including in developing countries with economic constraints, and in a cost-conscious healthcare environment. In one embodiment, disclosed are formulations that include chlorhexidine (CHX), curcumin (CUR), for example, curcumin C3 complex, and a silver (Ag) salt. Other embodiments pertain to compositions that include CHX, Ag and a lubricating agent. The antimicrobial coatings made according to embodiments of the invention are easier to produce, have superior efficacy and devices coated with this composition show initial release of antimicrobials and prolonged prevention of bacterial adherence, compared to currently available alternatives, to significantly reduce device-related infection especially catheter associated urinary tract infection.

  • Patent number: 9981069
    Abstract: The present invention relates to methods and compositions for rendering a surface resistant to bio-film formation by a combination of an alkanediol and an antimicrobial agent (and, optionally, an organic hydroxy acid). The invention provides for compositions which may be used to render surfaces bio-film resistant, articles having bio-film resistant surfaces, and methods for their preparation. The present invention may be advantageously applied to medical articles as well as articles used in non-medical contexts, such as child care or food preparation.
