Abstract: A hydrophilic biocompatible sustained-release material is disclosed. The material comprises amounts of an ethylene oxide/propylene oxide block copolymer, HPMC, and water, effective to produce a composition of sufficiently low viscosity at room temperature to be injectable into an internal body cavity via a tube inserted within a urinary catheter. At body temperature, the material exhibits a much higher viscosity and will stably adhere to the internal surface of a body cavity. As the material dissolves, a therapeutic agent incorporated therein is slowly released to the body cavity, while the material itself is excreted from the body.

Abstract: A method of providing sustained-release topical treatment of a condition affecting an internal body cavity is provided. The method comprises administering a pharmaceutical composition comprising a thermoreversible hydrogel and an active pharmaceutical ingredient to an internal body cavity of the urinary tract. After administration, the concentration of the active pharmaceutical ingredient in urothelium of the internal body cavity is increased when compared to the concentration of the active pharmaceutical ingredient in urothelium of the internal body cavity following administration of a control composition comprising the same dose and concentration of active pharmaceutical ingredient in water.

Abstract: A hydrophilic biocompatible sustained-release material is disclosed. The material comprises amounts of Pluronic F-127, PEG-400, HPMC and water, effective to produce a composition of sufficiently low viscosity at room temperature to be injectable into an internal body cavity via a tube inserted within a urinary catheter. At body temperature, the material exhibits a much higher viscosity and will stably adhere to the internal surface of a body cavity.
