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

Patent number: 5977164Abstract: A pharmaceutical formulation of taxol and polyethoxylated castor oil is disclosed to be relatively acidified to pH of less 8.1 and preferably within a pH range of 5 to 7, inclusively, by an acidifying agent. Ethanol is optionally included in the formulation which is adapted for use in a body for the treatment 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 taxol 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 taxol before mixing with the carrier solution. A variety of acidifying agents, a preferred one being anhydrous citric acid, are described.Type: GrantFiled: November 26, 1997Date of Patent: November 2, 1999Assignee: NaPro BioTherapeutics, Inc.Inventors: David Carver, Timothy Prout, Hernita Ewald, Robyn Elliott, Paul Handreck

Patent number: 5972992Abstract: A pharmaceutical formulation of taxol and polyethoxylated castor oil is disclosed to be stabilized by reducing its pH to 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 reducing the pH of a carrier material, such as polyethoxylated castor oil, to form a carrier solution after which taxol 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 taxol before mixing with the carrier solution.Type: GrantFiled: February 24, 1998Date of Patent: October 26, 1999Assignee: NaPro Biotherapeutics, Inc.Inventors: David Carver, Timothy Prout, Hernita Ewald, Robyn Elliott, Paul Handreck
