Abstract:
The present invention relates to compositions comprising a combination of one or more antiseptic and an antibiotic. It is based, at least in part, on the discovery that such combinations tend to deter the formation of antibiotic-resistant organisms. In preferred, nonlimiting embodiments of the invention, the antibiotic is minocycline and the antiseptic is a chlorhexidine compound, triclosan, or benzalkonium chloride, and in particular embodiments, a silver salt or a bismuth salt is added. Examples of specific, nonlimiting embodiments of the invention include combinations of (i) minocycline, triclosan, and a bismuth salt; (ii) minocycline, a chlorhexidine compound, and a bismuth salt; and (iii) minocycline, benzalkonium chloride, and a bismuth salt. The present invention further provides for articles, such as, but not limited to, medical articles, which have been treated with or which otherwise comprise a combination of antiseptic and antibiotic.
Abstract:
The present invention relates to polymeric medical articles comprising combinations of triclosan and silver-containing compounds. It is based, at least in part, on the discovery that these agents act synergistically, thereby permitting the use of relatively low levels of both agents. While it had been previously found that triclosan can be particularly useful when used in conjunction with chlorhexidine, it has been further discovered that medical articles having suitable antimicrobial properties may be prepared, according to the present invention, which contain triclosan without chlorhexidine. Such medical articles offer the advantage of preventing or inhibiting infection while avoiding undesirable adverse reactions to chlorhexidine by individuals that may have sensitivity to chlorhexidine.
Abstract:
The present invention relates to the use of organic salts of zinc in topical formulations. Such organic salts tend to be less water soluble and therefore less likely to result in systemic toxicity, even with chronic use. In preferred embodiments, the composition of the invention comprise zinc salicylate, which provides the antiinflammatory effect of salicylate, but wherein the zinc moiety counteracts toxic effects associated with salicylate.
Abstract:
The present invention relates to an antimicrobial glove which exhibits rapid release of the antiinfective agent chlorhexidine. It is based, at least in part, on the discovery that when a slurry having a high ratio of chlorhexidine to starch lubricant, where the percentage of starch lubricant is between 7 and 10 percent, is used to coat the inner surface of a latex glove, the resulting antimicrobial activity is available surprisingly quickly, within about 30 seconds to one minute of exposure to liquid. This rapid release of antiinfective agent may be explained by the presence, in gloves according to the invention, of two matrix layers, one comprising the starch lubricant, the other comprising latex in the body of the glove in immediate apposition to the lubricant, both of which are supersaturated with chlorhexidine.
Abstract:
Antimicrobial compositions having synergistic combinations of octoxyglycerin and at least one other antimicrobial agent in formulations which are more effective than prior art compositions without causing increased irritation to the skin of the average user. In certain embodiments, skin irritation may be minimized by low concentrations of antimicrobials and/or the presence of soothing compounds such as zinc. Preferred embodiments include combinations of octoxyglycerin, a quaternary compound, and at least one other antimicrobial agent. Without being bound to any particular theory, it is hypothesized that the unexpected antimicrobial effectiveness of combinations of octoxyglycerin may result from an enhancement of the permeability of microbes to antimicrobials caused by octoxyglycerin. Hydroalcoholic gel composition containing alcohol, water, hydrogel, and emollient or emulsifier, wherein the composition has a viscosity of below 2000 centipoises at between 20 and 40° C. This skin-friendly hydroalcoholic gel composition, which can be further combined with silicone polymer, emollient solvent, thickening agent and antimicrobial agent, enhances rapid and long-term antimicrobial efficacy.

Abstract:
The present invention relates to polymeric medical articles comprising the anti-infective agents chlorhexidine and triclosan. It is based, at least in part, on the discovery that the synergistic relationship between these compounds permits the use of relatively low levels of both agents, and on the discovery that effective antimicrobial activity may be achieved when these compounds are comprised in either hydrophilic or hydrophobic polymers. It is also based on the discovery that chlorhexidine free base and triclosan, used together, are incorporated into polymeric medical articles more efficiently. Medical articles prepared according to the invention offer the advantage of preventing or inhibiting infection while avoiding undesirably high release of anti-infective agent, for example into the bloodstream of a subject.
