Plasma protein adsorption patterns on surfaces of Amphotericin B-containing fat emulsions

Int J Pharm. 2003 Mar 18;254(1):3-5. doi: 10.1016/s0378-5173(02)00667-1.

Abstract

Nephrotoxicity of the conventional Amphotericin B formulation Fungizone is the most common side effect in treatment of systemic fungal infections. Lipid formulations of Amphotericin B including fat emulsions showed a reduced nephrotoxicity. In vivo distribution studies of lipid formulations have shown an accumulation of Amphotericin B in liver and spleen, while concentration in the kidneys is reduced. Blood proteins adsorbed onto particles after intravenous administration are regarded as the key factors determining their in vivo fate. Two-dimensional polyacrylamid gel electrophoresis is a powerful tool for analysis of protein adsorption patterns. This paper deals with the question if there is any correlation between proteins adsorbed on surfaces of AmB fat emulsions produced with a new production technique and the potentially organ distribution of this formulation.
