[On the spasmolytic action of 3-butoxy-1-phenoxy-propanol-(2) (febuprol) on the biliary tract (author's transl)].

The spasmolytic activity of 3-butoxy-1-phenoxy-propanol-(2) (febuprol) on the biliary tract is demonstrated in two different experimental arrangements in anesthetized dogs. This effect on the spasm provoked by morphine or prostigmine is illustrated by measuring the alteration of pressure in the choledochal duct. The spasmolytic efficacy of febuprol is significant and indicates a favourable secondary therapeutic effect of this substance.
