Summary
Atropine and benactyzine enhance the hypermotility produced by amphetamine and cocaine, but diminish the hypermotility caused by α-methyltryptamine. Tremorine decreases amphetamine hypermotility. Methylsergide increases hypermotility produced by amphetamine and does not influence the effect of cocaine and α-methyltryptamine. Chlorpromazine and phenoxybenzamine diminish hypermotility produced by all the three excitants.
Reserpine inhibits the effect of cocaine and α-methyltryptamine and does not influence that of amphetamine.
Prenylamine diminishes the effect of amphetamine, cocaine and methyltryptamine.
The possible significance of these findings is discussed.
