Moderate

prilocaine ibutilide

Applies to: prilocaine and ibutilide

MONITOR: Amide-type local anesthetics may have additive cardiac effects (e.g., bradycardia, chest pain, heart block, arrhythmias, ECG abnormalities, cardiac arrest) with class III antiarrhythmic agents. Although specific trials studying the interaction have not been performed, a case report suggests additive depressive effects of amiodarone and lidocaine on the sinoatrial node. A 64-year-old man with sick sinus syndrome developed severe, symptomatic sinus bradycardia and sinoatrial arrest following local anesthesia with lidocaine while he was on amiodarone therapy. No other cause was identified.

MANAGEMENT: Patients treated with class III antiarrhythmic agents (e.g., amiodarone, dofetilide, ibutilide, sotalol) should be under close surveillance during administration of amide-type local anesthetics. ECG monitoring should be considered.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
