This invention is concerned with a novel polymorphic forms of the compound 2-(R)-(1-(R)-(3,5-bis(trifluoromethyl)phenyl)ethoxy)-4-(5-(dimethyl-amino)methyl-1,2,3-triazol-4-yl)methyl-3-(S)-(4-fluorophenyl)morpholine hydrochloride 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 forms have advantages over the other known forms of 2-(R)-(1-(R)-(3,5-bis(trifluoromethyl)phenyl)ethoxy)-4-(5-(dimethylamino)methyl-1,2,3-triazol-4-yl)methyl-3-(S)-(4-fluorophenyl)morpholine hydrochloride in terms of thermodynamic stability and suitability for inclusion in pharmaceutical formulations.
本发明涉及一种新型多态形式的化合物2-(R)-(1-(R)-(3,5-双三氟甲基苯基)乙氧基)-4-(5-(二甲氨基)甲基-1,2,3-三唑-4-基)甲基-3-(S)-(4-氟苯基)吗啡啡曲马琳盐酸盐,该化合物是一种缓释激肽受体拮抗剂,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。此多态形式相对于已知的2-(R)-(1-(R)-(3,5-双三氟甲基苯基)乙氧基)-4-(5-(二甲氨基)甲基-1,2,3-三唑-4-基)甲基-3-(S)-(4-氟苯基)吗啡啡曲马琳盐酸盐的其他形式具有热力学稳定性和适合制药配方的优点。
