title: [Antiarrhythmic properties of opioid receptor agonists].
abstract: Data on the antiarrhythmic properties of opioid receptor (OR) agonists have been systematized. An analysis of published works which indicate that opioids increase cardiac tolerance to arrhythmogenic influences both in vivo and in vitro has been performed. For example, occupancy of central micro- and delta-OR and also ORL1 receptors increases cardiac tolerance to arrhythmogenic action epinephrine and aconitine. In contrast, activation of central kapa-OR exacerbates arrhythmogenic action epinephrine. Stimulation of peripheral delta2- and kappa1-OR decreases an incidence of arrhythmias induced coronary artery occlusion and reperfusion in vivo. Occupancy of peripheral micro-, kappa2-, delta1-OR and also ORL1 receptors has no effect on the cardiac tolerance to arrhythmogenic action of ischemia and reperfusion but increases cardiac electrical stability in rats with post-infarction cardiosclerosis. Authors suggest that opioids which unable penetrate to blood barrier may be used for therapy of arrhythmias.
