Bretylium Disease Interactions

There are 2 disease interactions with bretylium:

Major

Antiarrhythmics (Includes Bretylium) ↔ Cardiovascular Dysfunction

Severe Potential Hazard, High plausibility

Applies to: Congestive Heart Failure, Hypotension

Antiarrhythmic agents can induce severe hypotension (particularly with IV administration) or induce or worsen congestive heart failure (CHF). Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.

Major

Antiarrhythmics (Includes Bretylium) ↔ Proarrhythmic Effects

Severe Potential Hazard, High plausibility

Applies to: Arrhythmias

Antiarrhythmic agents can induce or worsen ventricular arrhythmias. Ventricular tachycardia, ventricular fibrillation, and torsades de pointes have occurred in some patients. Patients with underlying cardiac dysfunction, bradycardia, hypokalemia, hypomagnesemia, or high antiarrhythmic serum concentrations are at increased risk for drug-induced arrhythmias. Therapy with antiarrhythmics should be used with extreme caution in patients with or predisposed to arrhythmias. Evidence of improved survival is lacking for use of antiarrhythmic therapy in asymptomatic, non-life-threatening arrhythmias. Therapy with antiarrhythmic agents should be reserved for patients with life-threatening arrhythmias.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

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.

Do not stop taking any medications without consulting your healthcare provider.
