Abstract:
The present invention generally relates to suspension compositions having a carboxyvinyl polymer such as a carbomer, a galactomannan such as guar, and a borate compound. A sparingly soluble particulate compound such as nepafenac is also included in the compositions. The sparingly soluble particulate compound has a small particle size to enhance bioavailability of the compound.
