Abstract

Nonselective agonists of μ- and δ-opioid receptors dalargin (D-Ala2,Leu5,Arg6-enkephalin) and DADLE (D-Ala2,D-Leu5-enkephalin) administered immediately before coronary reperfusion in a dose of 0.1 mg/kg prevented the development of ventricular arrhythmias. Blockade of μ-opioid receptors abolished the antiarrhythmic effect of these peptides. Hence, antiarrhythmic activity of dalargin and DADLE is primarily associated with activation of μ-opioid receptors.
