6-Methoxy-1H-benzotriazole-5-carboxamide derivatives which are represented by the formula (I) below: ##STR1## \x9bin which R.sup.1 stands for ethyl or cyclopropylmethyl group, R.sup.2 stands for hydrogen atom, methyl or ethyl group, n is 1, 2 or 3, and the wavy line () signifies that configuration of the substituents on the carbon atom bound to the N-atom in the amide moiety is racemic (RS) or optically active (R or S)! or their pharmaceutically acceptable acid addition salts; processes for their preparation; pharmaceutical compositions containing a compound of formula (I) or its pharmaceutically acceptable acid addition salt; and novel intermediates. The compounds of the present invention possess concurrently excellent antiemetic activity and gastrointestinal motility enhancing activity. They furthermore exhibit less central nervous system (CNS) depressant activity and, therefore, are used for treatments and prophylaxis of functional disorders of gastrointestinal tract associated with various diseases and therapeutical treatments, as gastrointestinal motility enhancing agent.
以下是以式子(I)表示的6-甲氧基-1H-苯并三唑-5-羧酰胺衍生物:##STR1## 在式中,R^1代表乙基或环丙甲基基团,R^2代表氢原子、甲基或乙基基团,n为1、2或3,波浪线()表示酰胺基中与N原子相结合的碳原子上取代基的构型是外消旋体(RS)或光学活性体(R或S)!或其药学上可接受的酸加盐;制备它们的方法;含有式(I)化合物或其药学上可接受的酸加盐的制药组合物;以及新的中间体。本发明化合物同时具有优异的抗恶心活性和胃肠动力增强活性。此外,它们表现出较少的中枢神经系统(CNS)抑制活性,因此,它们用于治疗和预防与各种疾病和治疗方法相关的胃肠道功能障碍,作为胃肠动力增强剂。
