Evaluation of Bay R 3783 in rodent models of superficial and systemic candidiasis, meningeal cryptococcosis, and pulmonary aspergillosis.

The triazole Bay R 3783 was compared with fluconazole, itraconazole, ketoconazole, and amphotericin B in rodent models of superficial and systemic candidiasis, meningocerebral cryptococcosis, and pulmonary aspergillosis. Overall, Bay R 3783 was comparable or slightly superior to fluconazole and markedly superior to itraconazole and ketoconazole in both survival and short-term organ load experiments in models of candidiasis and cryptococcosis but was less effective than amphotericin B. Of the antifungal agents tested, only Bay R 3783 and itraconazole showed any efficacy in the model of pulmonary aspergillosis.
