  • Patent number: 8436050
    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.

  • Publication number: 20050192547
    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.

  • Publication number: 20050124725
    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.

  • Patent number: 6872195
    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.
