In leukopenic mice with severe systemic candidiasis, single-dose
treatment (5 mg of amphotericin B [AMB]/kg of body weight) with
long-circulating polyethylene glycol-coated AMB liposomes (PEG-AMB-LIP) resulted in zero mortality and a significant
reduction in the number of viable Candida albicans in the
kidney, whereas 70% mortality was seen in mice treated with
five daily doses of AmBisome (5 mg of AMB/kg · day). When the
first of five daily doses of AmBisome was combined with a single low
dose of Fungizone (0.1 mg of AMB/kg), the efficacy was equal to that of
PEG-AMB-LIP.
