An external preparation which is excellent in the adhesion to and residence in the living organism and can be improved in suspension stability. The preparation comprises an aqueous solution of a temperature-sensitive polymer and a water-soluble or insoluble drug for external use. It is sol at a temperature below that of the living organism but turns into gel at the surface temperature of the same. The gel is water-insoluble and the sol-gel conversion is reversible.
