| Summary: | Amphotericin B is a polyene antifungal drug used intravenously for systemic fungal infections.
It has severe and potentially lethal side effects, therefore, it has been limited use in clinical.
Liposomes are widely used as vehicles to target organ in pharmaceutical technology due to their
ability to improve the delivery of drugs, increasing therapeutic efficacy and decreasing toxicity. The
aim of this study is to prepare a liposomal amphotericin B by hydration of a thin lipid film and
ethanol-injection methods and evaluate its antifungal activity in vivo. Prepared liposomal
amphotericin B by both methods has particle size smaller than 150 nm, quite homogeneous and the
entrapment drug was greater than 90%. The antifungal activity of liposomal amphotericin B was
studied on three strains Candida albicans, Cryptococcus neoformans andAspergillus fumigatus
fungal infection in mice models. Our results have shown that liposomal amphotericin B prepared
by both methods have strong effect to prolong the survival in the infected mice and significantly
reduced the Colony Forming Units (CFU) in target organ with similar effect of AmBisome |
