Publication number: 20040204479Abstract: 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.Type: ApplicationFiled: April 29, 2004Publication date: October 14, 2004Inventors: David Carver, Timothy Prout, Hernita Ewald, Robyn Elliott, Paul Handreck

Publication number: 20030138462Abstract: 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.Type: ApplicationFiled: November 6, 2002Publication date: July 24, 2003Applicant: Mayne Pharma Pty Ltd.Inventors: Gregory Paul Handreck, Wei Zhou, Russell John Tait
