EFFECT OF ELECTROSHOCK AND ANTIDEPRESSANT DRUGS ON CEREBROVASCULAR PERMEABILITY TO COCAINE IN THE RAT

Abstract
The data presented in this work demonstrate that treatment of the rat with the antidepressant drugs, imipramine, amitriptyline, and nortriptyline, results in permeability changes in the central nervous system on approximately the same order of magnitude as such changes induced by electroshock. In contrast to the effect of the antidepressant drugs, treatment with chloropromazine does not significantly alter the blood-brain barrier permeability to cocaine in the rat. It is suggested that these results lend support to the concept that the therapeutic effects of electroshock may be related in some way to its action on cerebrovascular permeability.
