A method is disclosed for controlling emesis utilizing N-(1-substituted-3-pyrrolidinyl)benzamides and thiobenzamides of the formula: ##SPC1## Wherein R is cycloalkyl, phenyl and phenyllower-alkyl; R.sup.1 is hydrogen, lower alkyl of 1 to 8 carbon atoms and phenyl; R.sup.2 is halogen, lower-alkyl, lower-alkoxy, amino, nitro, monoalkylamino, dialkylamino, mercaptomethyl, acetamido, sulfamoyl, cyano, hydroxy, benzyloxy, and trifluoromethyl; X is oxygen and sulfur; n is an integer from zero to three inclusive and pharmaceutically acceptable acid addition salts thereof. The benzamide compounds wherein R is cyclohexyl and R.sup.1 is lower-alkyl are particularly effective as antiemetics and have minimal side effects.
本发明揭示了一种利用N-(1-取代-3-
吡咯烷基)苯甲酰胺和
硫代苯甲酰胺控制呕吐的方法,其
化学式为:##
SPC1## 其中R为环烷基、苯基和苯基低烷基;R.sup.1为氢、1至8个碳原子的低烷基和苯基;R.sup.2为卤素、低烷基、低烷氧基、
氨基、硝基、单烷基
氨基、双烷基
氨基、巯基甲基、乙酰胺基、磺酰胺基、
氰基、羟基、苄氧基和三
氟甲基;X为氧和
硫;n为0至3的整数,以及其药学上可接受的酸盐。其中,R为环己基且R.sup.1为低烷基的苯甲酰胺化合物特别有效作为止吐剂,并具有最小的副作用。
