Abstract
Evidence supporting the hypothesis that GABA-ergic mechanisms are involved in controlling mammalian cardiovascular function has been reviewed and analyzed. In vivo and in vitro studies with GABA-agonists and GABA-antagonists have revealed that activation of GABA-receptors is involved in the control of blood pressure and heart rate. Further studies conducted with agents that modify central and/or peripheral GABA-ergic systems could lead to the discovery of drugs that might be useful for treating certain cardiovascular disorders in man, such as hypertension and stroke, and should increase our understanding of the pathophysiological bases of such disorders.
