The effect of kappa receptors agonists and antagonists was studied in the model of epinephrine induced arrhythmias. Kappa receptor agonists U-50,488 and [D-Ala2]-Dynorphin A (1-13) administered ICV potentiate the arrhythmogenic effect of epinephrine. The effect of U-50,488 was completely blocked by kappa receptor antagonist, nor-binaltorphine. Administration of N-cholinergic receptor inhibitor, hexamethonium, prevented pro-arrhythmic effects of U-50,488 and [D-Ala2]-Dynorphin A (1-13). The data support the hypothesis that central kappa opioid receptors play an important role in the arrhythmogenesis.
