  • Publication number: 20140287016
    Abstract: The invention provides methods of immobilizing an active agent to a substrate surface, including the steps of, depositing a primer compound on a substrate, thereby forming a primed substrate, contacting the primed substrate with a solution of a compound including a trihydroxyphenyl group, thereby forming a trihydroxyphenyl-treated primed substrate, and contacting the trihydroxyphenyl-treated primed substrate with a solution of an active agent, thereby immobilizing the active agent on the substrate. Further provided are methods of immobilizing an active agent on a substrate, including the steps of providing a substrate, combining a solution of a compound including a trihydroxyphenyl group with a solution of an active agent, thereby forming a solution of an active agent-trihydroxyphenyl conjugate, and contacting the primed substrate with the solution of the active agent-trihydroxyphenyl conjugate, thereby immobilizing the active agent on the substrate.

  • Patent number: 7776360
    Abstract: The present invention is directed to novel compounds, methods of manufacture and methods of use. The present invention is also directed to solid drug/active agent particles having one or more of the compounds of the present invention associated with the surface thereof. The compounds of the present invention are comprised of a non-polar polyether covalently linked to an anionic sulfonate group. The compounds have an amphipathic quality and preferably, are surface active. Such compounds are preferably useful as surface-active agents to coat and stabilize dispersions of particles in a continuous liquid medium. These surface-active agents may be applied in the stabilization of suspensions, emulsions, or liposome formulations intended for pharmaceutical, medical, cosmetic, or agricultural use. The particles that can be prepared by a variety of methods and will preferably comprise a pharmaceutical agent.

  • Publication number: 20100197817
    Abstract: A method for immobilizing dyes and antimicrobial agents on a polymeric cover or housing for a medical device is disclosed and described. The surface may be that of a catheter, a connector, a drug vial spike, a bag spike, a prosthetic device, an endoscope, a surface of an infusion pump, a key pad, a touch screen or a handle. The surfaces may also be one or more of those associated with a infusion of a medicament or dialysis treatment, such as peritoneal dialysis or hemodialysis, where it is important that the working surface for the dialysis fluid be sterile. These surfaces include connectors for peritoneal dialysis sets or for hemodialysis sets, bag spikes, dialysis catheters, and so forth. A method for determining whether a surface has been sterilized, and a dye useful in so indicating, is also disclosed.
