Abstract: front page image
(EN)This invention relates to novel polymorphic/pseudopolymorphic forms of 5-[4-[2[N-methyl-N-(2-pyridyl)amino]ethoxy]benzyl] thiazolidine-2,4-dione maleate 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 agent, than the hitherto known 5-[4-[2-[N-(2-methyl-N-(2-pyridyl)amino]ethoxy]benzyl] thiazolidine-2,4-dione maleate.
(FR)L'invention concerne des nouvelles formes polymorphes/pseudo-polymorphes de 5-[4-[2[N-méthyl-N-(2-pyridyl)amino]éthoxy]benzyl] thiazolidine-2,4-dione maléate de formule (I). L'invention concerne également une composition pharmaceutique renfermant les nouvelles formes polymorphes ou un mélange de celles-ci et un adjuvant acceptable sur le plan pharmaceutique. Les formes polymorphes selon l'invention sont plus actives, comme agent anti-diabétique, que le 5-[4-[2-[N-(2-méthyl-N-(2-pyridyl)amino]éthoxy]benzyl] thiazolidine-2,4-dione maléate connu jusqu'à présent.
