Amphotericin B in combination with 5-fluorocytosine was synergistic against three clinical isolates of Aspergillus fumigatus and one of three clinical isolates of A. flavus. Amphotericin B in combination with rifampin was synergistic against all six clinical isolates of Aspergillus tested. The levels of 5-fluorocytosine and rifampin required for synergism were higher than clinically achievable concentrations when measurements of synergism were based on visual turbidity; but when the effects of the drugs were measured by inhibition of ribonucleic acid synthesis or dry-weight increase, much lower concentrations were effective.
两性霉素B与5-氟胞嘧啶联合使用对三株烟曲霉临床分离株及三株黄曲霉临床分离株中的一株具有协同作用。两性霉素B与利福平联合使用对所检测的所有六株曲霉临床分离株均具有协同作用。当基于视觉浊度测量协同作用时,协同所需的5-氟胞嘧啶和利福平水平高于临床可达到的浓度;但当通过抑制核糖核酸合成或干重增加来测量药物作用时,低得多的浓度就有效。
