[Effect of aminazine and droperidol on the coronary circulation and its regulation]

Experiments conducted on dogs with the help of resistography showed chlorpromazine capable of reducing the resistance of the coronary vessels, whereas droperidol and not have any regular effect on the resistance of the cardiac vessels to the blood flow. Both drugs inhibited pressor and depressor reflexes on the coronary vessels reproduced by the stimulation of afferent fibers of the tibial and vagal nerves, as well as the response of the coronary vessels to the administration of epinephrine and norepinephrine.
