Summary for Patent: 6,592,903
Title: Nanoparticulate dispersions comprising a synergistic combination of a polymeric surface stabilizer and dioctyl sodium sulfosuccinate
Abstract:Disclosed are solid dose nanoparticulate compositions comprising a poorly soluble active agent, at least one polymeric surface stabilizer, and dioctyl sodium sulfosuccinate (DOSS). The solid dose compositions exhibit superior redispersibility of the nanoparticulate composition upon administration to a mammal, such as a human or animal. The invention also describes methods of making and using such compositions.
