  • Publication number: 20040204479
    Abstract: A pharmaceutical formulation of paclitaxel and polyethoxylated castor oil is disclosed to be relatively acidified to a pH of less than 8.1 and preferably within a pH range of 5 to 7, inclusively. Ethanol is optionally included in the formulation which is adapted for use in a body for the treatment of cancer. A formulation method is disclosed and includes the step of mixing an acid with a carrier material, such as polyethoxylated castor oil, to form a carrier solution after which paclitaxel is added in an amount such that the resulting pH is less than 8.1 and preferably in a pH range of 5 to 7. Ethanol may optionally be slurried with the paclitaxel before mixing with the carrier solution. A variety of acidifying agents, a preferred one being anhydrous citric acid, are described.

  • Publication number: 20040082545
    Abstract: A pharmaceutical product containing pamidronate and other diphosphonate solutions in an appropriate container, a pH of between 5 and 8 and without organic acid buffer or polyethylen glycol. The container may be treated glass or made of other appropriate material. Coated elastomeric stoppers are also included. A method of producing a pharmaceutical product comprising steps of making a suspension of pamadronic acid, adding sodium hydroxide, to form a solution adjusting the pH to between 5 and 8 and transferring the solution to a container.

  • 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.
