  • Publication number: 20030138462
    Abstract: A stable injectable solution containing pamidronate and a method for preparing a therapeutic aqueous disodium pamidronate solution. The method comprises preparing a slurry of pamidronic acid in water, combining aqueous sodium hydroxide with the slurry in an amount about 2:1 molar ratio of sodium hydroxide to pamidronic acid to yield a solution of disodium pamidronate having visual clarity and a pH of about 6.5, and packaging the solution in sealed containers. A unit dosage form including the solution and a vial or ampule comprising the unit dosage form are also described.
