The stretched attend posture (SAP) in the mouse is an investigatory forward elongation of the body in a novel environment. In a previous study, the anxiolytics diazepam, clobazam, and phenobarbital reduced SAP, and low doses of the non-anxiolytics imipramine and chlorpromazine were ineffective, results which prompted the investigator to propose the SAP test as a screening method for anxiolytics. However, diazepam and clobazam also increased immobility. In the present study, the anxiolytics chlordiazepoxide, pentobarbital, and buspirone and behaviorally active doses of the non-anxiolytics chlorpromazine and morphine reduced SAP and tended to increase immobility. We concluded that therapeutic-class specificity has not been demonstrated for the SAP test.
