Abstract

This study provides the first behavioral evidence in support of an α-adrenergic mechanism underlying imipramine's amelioration of separation distress. The rate of separation-induced vocalization by adult squirrel monkeys was decreased by imipramine and the α2-adrenergic agonist clonidine, and increased by the α2-adrenergic antagonist yohimbine. Yohimbine, but not the α1-antagonist prazosin, reversed the clonidine effect suggesting that drugs acting directly on α2-receptors may have a role in management of separation anxiety.
