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.

Non-Orange Book US Patents Family Members for Patent 6,592,903

For Orange Book-listed patents (shown in the main table above) generic applications must certify that the listed patents are expired, invalid, or will not be infringed by generic entry.

The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
