Antimicrobial compositions useful for medical applications
Patent 5326567 Issued on July 5, 1994. Estimated Expiration Date: June 28, 2013. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
Antimicrobial metal-based compositions, which are photostable, non-staining, and which are easily absorbed into lipophilic matrices, contain silver cations, complexed by acyclic polyether polymers through the formation of a "host-guest relationship" where the acyclic polyether is the "host" and the silver cation is the "guest," wherein stabilization of this "host-guest relationship" is accomplished through the use of excess halide anions. The compositions are useful for topical treatment of infections caused by bacteria, fungus and viruses in humans and animals and for treating medical devices and adhesives to impart infection-resistance.
