The invention concerns spasmolytically active pharmaceutical compositions, and the preparation thereof, containing (+) S-1-cyclohexyl-4-[ethyl-(p-methoxy-a-methylphenethyl)amino]-1-butanone or a salt thereof as the active component.
It has been found that this (+) S-enantiomer is about twice as active as the racemate (which is known as secoverine). This better activity is not related with a proportional increase of undesired side-effects.
本发明涉及具有解痉活性的药物组合物及其制备方法,其活性成分为(+) S-1-环己基-4-[乙基-(对甲氧基-a-甲基苯乙基)
氨基]-1-
丁酮或其盐。
研究发现,这种 (+) S-对映体的活性约为外消旋体(即 secoverine)的两倍。这种较好的活性与不良副作用的增加并不成正比。
