  • Publication number: 20060276525
    Abstract: Processes are disclosed for preparing Telmisartan form A, which is free-flowing and which does not contain electrostatic charge and is thus industrially process-able. The free-flowing Telmisartan form A is prepared by crystallization from a polar organic solvent e.g., DMSO, DMF, DMA, NMP, or water and is suitable for use in pharmaceutical compositions. A process is also disclosed for preparing highly-pure Telmisartan form A by precipitation from aqueous solutions.
