KB-R7943, a Na+/Ca2+ exchange inhibitor, does not suppress ischemia/reperfusion arrhythmias nor digitalis arrhythmias in dogs

KB-R7943 (2-[2-[4-(4-nitrobenzyloxy) phenyl] ethyl] isothiourea methanesulfonate) has been
used as a pharmacological tool to block the Ca 2+ influx-mode of the Na+/Ca 2+ exchanger,
which is thought to contribute to ischemia/reperfusion and digitalis arrhythmias. We
examined effects of KB-R7943 on ischemia/reperfusion arrhythmias in beagle dogs
anesthetized with sodium pentobarbital. Lead II ECG and BP were measured. KB-R7943 or
the solvent (10% DMSO) was injected iv as a bolus, and 5 min later, the left anterior …
