This invention is concerned with a novel polymorphic form of the compound 2-(R)-(1-(R)-(3,5-bis(trifluoromethyl)-phenyl)-ethoxy)-3-(S)-(4-fluoro)phenyl-4-(3-(5-oxo-1H,4H-1,2,4-triazolo)methylmorpholine which is a tachykinin receptor antagonist useful in the treatment or prevention of disorders of the central nervous system, inflammatory diseases, pain or migraine, asthma, and emesis. The instant polymorphic form has advantages over the other known forms of 2-(R)-(1-(R)-(3,1-bis(trifluoro-methyl)-phenyl)ethoxy)-3-(S)-(4-fluoro)phenyl-4-(3-(5-oxo-1H,4H-1,2,4-triazolo)methylmorpholine in terms of thermodynamic stability and suitability for inclusion in pharmaceutical formulations.
这项发明涉及一种新的多晶型化合物2-(R)-(1-(R)-(3,5-双三氟甲基苯基)-乙氧基)-3-(S)-(4-氟苯基)-4-(3-(5-氧代-1H,4H-1,2,4-三唑基)甲基吗啡啶,它是一种缓激肽受体拮抗剂,可用于治疗或预防中枢神经系统疾病、炎症性疾病、疼痛或偏头痛、哮喘和呕吐等疾病。这种多晶型具有比已知的其他形式的2-(R)-(1-(R)-(3,1-双三氟甲基苯基)乙氧基)-3-(S)-(4-氟苯基)-4-(3-(5-氧代-1H,4H-1,2,4-三唑基)甲基吗啡啶更好的热力学稳定性和适合用于制药配方的优点。
