Abstract
The present invention is an aqueous solution which contains two types of methyl celluloses, polyethylene glycol, polyvinylpyrrolidone, and citric acid or a pharmaceutically acceptable salt thereof. The composition of the present invention maintains a low viscosity around room temperature, but the composition is suddenly increased in the viscosity due to heat around the body temperature and has thixotropy even after gelation.
