The invention relates to new N-substituted benzenesulphonamides of general formula ##STR1## in which n is 2 or 3, R.sub.1 and R.sub.2 are hydrogen atoms, methyl, ethyl groups, or jointly form with the nitrogen a nitrogenized heterocyclic ring having 5 or 6 members, in particular a piperidino, pyrrolidino or morpholino group. R.sub.3 is a hydrogen atom, an NO.sub.2 group, an NH.sub.2 group, or a halogen, R.sub.4 is a hydrogen, a halogen, NH.sub.2 group or a sulphonamide group. These compounds are useful as active substances of medicaments, in particular as antiemetic.
本发明涉及新的N-取代苯磺酰胺,其一般式为##STR1##其中n为2或3,R.sub.1和R.sub.2为氢原子,甲基,乙基基团,或与氮一起形成具有5或6个成员的氮杂环环,特别是
哌啶,
吡咯烷或吗啉基团。R.sub.3为氢原子,NO.sub.2基团,NH.sub.2基团或卤素,R.sub.4为氢,卤素,NH.sub.2基团或磺酰胺基团。这些化合物可用作药物的活性物质,特别是作为抗恶心药物。
