Interaction Effect
An increased risk of cardiac arrhythmias
Interaction Summary
Concomitant digoxin and pancuronium therapy has been reported to result in cardiac arrhythmias. Possible mechanisms for this interaction include the vagolytic effect of pancuronium, the direct sympathomimetic and indirect sympathomimetic effects of pancuronium, and the prevention of norepinephrine reuptake by pancuronium.
Severity
Moderate
Onset
Rapid
Evidence
Established
How To Manage Interaction
Cardiac rhythm should be closely monitored when administering pancuronium to a digitalized patient.
Mechanism Of Interaction
Unknown
Literature Reports
A) The incidence of arrhythmias in digitalized patients who received either succinylcholine or pancuronium were compared. They divided 104 patients into four groups: Groups 1 and 2 were not receiving digitalis therapy, and Groups 3 and 4 were maintained on digoxin, diuretic therapy, and potassium supplementation. Patients in Groups 1 and 3 received succinylcholine 2 mg/kg while Groups 2 and 4 were administered pancuronium 0.12 mg/kg. Results showed that the incidence of dysrhythmias was significantly higher in the Group 4 patients who were receiving digoxin and pancuronium (6 out of 18 patients) than in Group 3, who received digoxin and succinylcholine (3 out of 46 patients). Types of arrhythmias seen in Group 4 included sinus tachycardia (n=4) and atrial flutter (n=2). Due to ethical reasons, the investigators terminated the administration of pancuronium to the digitalized patients .
