USPTO Abstract

Compositions with improved particle transport in mucus are provided. In some embodiments, the compositions and methods involve making mucus-penetrating particles (MPP) without any polymeric carriers, or with minimal use of polymeric carriers. The compositions may include modifying the surface coatings of particles formed of pharmaceutical agents that have a low water solubility. Such compositions can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications.
