Chitosan microparticulate delivery systems containing clotrimazole were prepared by a spray drying technique using glycerol 2-phosphate as an ion cross-linker. The impact of a cross-linking ratio on microparticle characteristics was evaluated. Drug-free and drug-loaded unmodified or ion cross-linked chitosan microparticles were examined for the in vitro cytotoxicity in VK2/E6E7 human vaginal ep...

OBJECTIVE To study the interaction of antifungal drugs in topical therapy. MATERIALS AND METHODS Local therapy of Candida vaginitis with drugs alone and in combination was examined in a murine model. Zeamatin, a natural plant-derived antifungal protein, was tested alone and in combination with an azole, clotrimazole or nikkomycin Z, a chitin synthase inhibitor. RESULTS Whereas alone, zeamat...

The emergence of metronidazole-resistant Trichomonas vaginalis and questions about the safety of metronidazole are significant concerns in treatment of trichomoniasis. At 24 h, a microtiter assay was used to test antimicrobial susceptibility of 16 recent isolates; the MICs of metronidazole ranged from less than 0.06 to 25 micrograms/ml. Observable motility as an endpoint correlated imperfectly ...

The in vitro antibacterial activity of the antifungal compound fenticonazole was compared with those of clotrimazole, miconazole, tetracycline, and metronidazole against 177 strains of bacterial species associated with either bacterial vaginosis (BV) or skin infections by agar dilution MIC determinations. BV-associated Bacteroides isolates of the Bacteroides melaninogenicus-B. oralis group, Gar...

OBJECTIVE The objective of this study was to investigate the antifungal activity of coronarin D on Candida albicans and its activity was compared with clotrimazole and nystatin. METHODS Coronarin D was extracted by liquid chromatography and used in antifungal testing. The inhibitory effect of coronarin D on C. albicans was determined by cultures and an applied broth dilution test. The rate of...
