[Characteristics of the psychotropic spectrum of action of mebicar].

Under group interaction in cats, a new Soviet tranquilizer mebicar eliminates fear-alarm induced by stimulatin of the emotiogenic zone of the hypothalamus. This action is not associated with myorelaxant or hypnotic action. Mebicar decreases the brain noradrenaline level, exerts no effect on the dopaminergic systems, increases the brain serotonin level, and does not elicit cholinolytic action.
