Nanocrystallization of poorly water soluble drugs for parenteral administration.

Approximately 50% active substances discovered by combinatorial chemistry and high-throughput screening show poor solubility in water. Out of various available approaches "Nanoedege technology" (Combination of Precipitation and Homogenization) was selected. Amphotericin B (Amp B) was used as a model drug. Three different preparations of Amp B were produced by using three different surfactants Tween80, Pluronic F68, Soya Lecithin and assessed for their efficacy and stability. In this study the Amp B nanosuspension formulation, with the smaller particle size, can be effectively produced with the Nanoedge Method. The pharmacokinetic profiles of Amp B when given in the nanosuspension formulation were different compared to the corresponding raw drug.
