[The participation of the central and peripheral kappa-opiate receptors in the mechanism of the anti-arrhythmia action of benzeneacetamide derivatives].
When injected intraperitoneally in a dose of 8 mg/kg, U-62066, the selective agonist of kappa-opioid receptors, exhibits antiarrhythmic properties in epinephrine-induced arrhythmias in rats. In cerebroventricular injection, the kappa-agonists U-50,488 and [D-ala2]-dynorphin A(1-13) manifest proarrhythmic properties. Preliminary administration of the kappa-antagonist nor-binaltorphimine completely removes the proarrhythmic and antiarrhythmic effect of kappa-agonists. The antiarrhythmic effect of U-62006 is believed to be associated with activation of peripheral kappa-receptors.
