Comparison of miconazole- and ketoconazole-induced release of K+ from Candida species

J Antimicrob Chemother. 1983 Apr;11(4):381-3. doi: 10.1093/jac/11.4.381.


Relatively high concentrations of miconazole caused immediate and rapid release of K+ from strains of Candida albicans and Can. parapsilosis. Ketoconazole did not. These results support the recent hypothesis that ketonocazole, unlike related antifungal imidazole-containing drugs, cannot exert a direct membrane damaging effect.
