Novel polymorphic forms of an antidiabetic agent: process for their preparation and a pharmaceutical composition containing them

摘要

This invention relates to novel polymorphic/pseudopolymorphic forms of arginine salt of 3-[4-[2-(phenoxazin-10-y1)ethoxy]pheny1]-2-ethoxypropanoic acid, having formula (I). The invention also relates to a pharmaceutical composition comprising the novel polymorphic form or their mixture and a pharmaceutically acceptable carrier. The polymorphic forms of the present invention are more active, as antidiabetic and hypolipidemic agent, than the novel 3-[4-[2-(phenoxazin-10-y1)ethoxy]phenyl]-2-ethoxypropanoic acid.
