Methods for particle size reduction of liposomal amphotericin B

Abstract

Liposomal amphotericin B were prepared by thin film hydration technique. Particle size was reduced by ultrasonic device and high pressure homogeneous device. The size distribution was determined by dynamic light scattering by the Zetasizer ZS90 equipment. The morphology of amphotericin B liposomes was observed by Transmission electronic microscopy (TEM) with negative staining technique. The result shows that combining high-pressure homogenization and membrane extrusion provided monolayer liposomal amphotericin B with particle size less than 200 nm and homogenously (PDI < 0.3).
