Eprosartan mesylate crystalline particles and a process for preparing pure eprosartan

摘要

The present invention relates to eprosartan mesylate particles having a relatively larger surface area, to the methods for the manufacture of said crystalline particles, and to pharmaceutical compositions comprising said crystalline particles. The present invention further relates to a crystalline solid of eprosartan acetate, to a process for its preparation and to a pharmaceutical composition comprising it. The present invention also provides substantially pure eprosartan free base and a process for its preparation.
