Abstract
A liquid composition for adherence to a bodily surface, notably to a bodily surface, especially a mucosal surface, comprises water-swellable polymer particles suspended in a water-miscible liquid diluent, wherein the liquid diluent is substantially free of water or includes an amount of water insufficient to fully swell the polymer particles. On admixture with water the composition thickens and becomes more adherent to surfaces. Thus the composition may be easy to administer but may become thick and adherent at the treatment site.
