From Dog

Yohimbine is produced as an extract from Pausinystalia yohimbe and other flora and is a respiratory stimulant used to improve recovery from general anesthesia[1].

It also induces colonic peristalsis[2], and is therapeutic against mild constipation, acting antagonistically against the diuretic effect of medetomidine[3], and the antidiarrheal drugs loperamide and diphenoxylate.

Recommended dose rate is 100 - 400 μg/kg given intravenously as required[4].
