Cefpodixime proxetil |
| abstract |
The present invention relates to an improved and cost effective process for the industrial manufacture of cefpodoxime proxetil. More specifically, the present invention relates to the preparation of cefpodoxime proxetil of high purity and yield. The process comprises a) dissolving impure cefpodoxime proxetil or adding a solution containing cefpodoxime proxetil into a polar organic solvent or mixture(s) thereof, optionally reducing the solvent by concentration, and adding into a non-polar organic solvent or mixture(s) thereof to precipitate the solid; and b) dissolving the solid obtained from the above step into water-miscible polar organic solvent, optionally reducing the solvent by concentration, adding it into water to obtain the pure cefpodoxime proxetil. |
