Dp. Kontoyiannis et al., Itraconazole-amphotericin B antagonism in Aspergillus fumigatus: an E-test-based strategy, ANTIM AG CH, 44(10), 2000, pp. 2915-2918
We examined an E-test-based strategy for testing the combination of itracon
azole and amphotericin B, the latter given either sequentially or concomita
ntly, in isolates of Aspergillus fumigatus. An antagonistic interaction bet
ween the two drugs was noted, especially with the sequential administration
of amphotericin B. This in vitro antagonism was reversible.
