title: Feasibility of using collagen as the base of the antifungal drug, miconazole.
abstract: The feasibility of using collagen as the base of miconazole was investigated. The addition of 33% collagen to a miconazole solution did not affect the minimal inhibitory concentration (MIC80) of the miconazole solution for Candida albicans. When 1 microg mL(-1) of miconazole in 33% collagen solution was plated on resin discs and dried to yield a thin membrane, the growth of C. albicans on the resin discs was nearly completely inhibited. In addition, we compared the antifungal effect of this collagen solution that contained 1 microg mL(-1) miconazole, with the antifungal effect of miconazole gel that had been diluted with glycerol (the main component of miconazole gel) to yield a final concentration of 1 microg mL(-1) of miconazole; as a result, we found that the collagen solution containing 1 microg mL(-1) miconazole had a stronger antifungal effect. In conclusion, our results demonstrated that it may be feasible to use collagen as the base of miconazole instead of glycerol, and suggest that a collagen-based miconazole solution would have a stronger antifungal effect than commercially available miconazole gel. Collagen-based miconazole solution may be useful for the treatment of Candida-associated denture stomatitis.
