TL;DR
It was found that some neuroleptic drugs antagonized, within a certain dose range, abnormal behaviour with a concomitant increase of exploratory motor activity, and the most active drugs in this sense were chlorpromazine and perphenazine.
Abstract
High doses of d-amphetamine cause stereotyped behaviour in rats and an absence of many normal activities such as exploratory motor activity. The antagonism of these two effects of amphetamine was studied by pretreatment with several neuroleptic, adrenolytic and cholinergic drugs. It was found that some neuroleptic drugs antagonized, within a certain dose range, abnormal behaviour with a concomitant increase of exploratory motor activity. The most active drugs in this sense were chlorpromazine and perphenazine. No significant effect was observed with the adrenolytic or cholinergic drugs studied. Some possible implications of the motor reversal by neuroleptic drugs are discussed.

The action of apomorphine on gnaw compulsion is, just as that of dopamine, directly on effect receptors, and may act as a substitute for dopamine deficiency in Parkinson's disease.

Experiments with chickens, pidgeons, mice, rats, guinea-pigs, cats, dogs, squirrel-monkeys and chimpanzees show that stereotyped activity can be produced by amphetamine in doses of 1–20 mg/kg in all these species ranging from birds to primates.
PsychopharmacologySpecial antagonism of amphetamine-induced abnormal behaviour
156 Citations1965A. Randrup, I. Munkvad
It has been shown, that perphenazine exerts a special form of antagonism against amphetamine, which inhibits a continuous stereotyped activity, which is induced by the amphetamine and simultaneously causes an increase in normal activities such as grooming and locomotion.

Pretreatment with monoamine oxidase inhibitors, which increased the stores of endogenous norepinephrine, enhanced the toxicity, while pretreatment with agents that reduced the tissue stores of nore Alpinephnine reduced the toxicity of d -amphetamine.

Stimulation of the central cholinergic system by Tremorine afforded protection against the lethal effect of Amphetamine in aggregated mice, reduced spontaneous motor activity, and antagonized the effect of amphetamine on motor activity.

Dl-α-amphetamine sulphate in a dose of 10 mg/kg caused abnormal stereotyped behaviour in white rats and major tranquillizers diminished or abolished this phenomenon; thymeretics increased its duration; minor tranquillizer did not influence it.

The results suggest that, while anorexia is completely independent of the other activities of amphetamine which were examined, hyperthermia and lethality may be closely related.

Chlorpromazine modified the disposition of amphetamine as evidenced by considerably higher and more sustained brain levels of the stimulant in rats which received the combined treatment and the similarity of the interaction of chlorpromazine and imipramine with amphetamine are discussed.
