    摘要: A pharmaceutical composition of a water soluble drug admixed with an aqueous bioadhesive cellulosic polymer containing microcrystalline particles. When sprayed (via a conventional spray device) into the nose, drug molecules are retained in contact with the nasal membrane. The drug composition comprises ketorolac tromethamine in an aqueous nasal polymeric spray formulation that without the addition of any permeation enhancer will promote drug absorption and provides absolute drug bioavailability greater than 90%.
