Abstract:
1. A pseudoplastic liquid composition for treating or inhibiting an oral mucocutaneous disorder, said liquid composition having a zero shear viscosity at 37±1 degrees Celsius of 100-20,000 centipoise, comprising 0.1 to 3.0 wt/wt % of one or more mucoadhesives in an aqueous solution, wherein the mucoadhesive(s) is/are one or more linear or cross-linked polymer(s) selected from the group consisting of polyacrylic acid, carbopol, carboxymethylcellulose, hydroxyalkylcellulose, dextran sulfate, chitosan, and a water-soluble vinyl polymer; wherein said liquid composition, when administered to an oral mucosa: 1) remains liquid when shear is applied due to swishing the liquid in the mouth; and 2) attaches to and coats the oral mucosa upon discontinuance of said shear.
