Ibutilide Disease Interactions

There are 3 disease interactions with ibutilide.

Major

Antiarrhythmics (applies to ibutilide) cardiovascular dysfunction

Major Potential Hazard, High plausibility. Applicable conditions: 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.

Moderate

Antiarrhythmics (applies to ibutilide) electrolyte imbalance

Moderate Potential Hazard, High plausibility. Applicable conditions: Hyperkalemia, Hypokalemia, Magnesium Imbalance

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.

Moderate

Ibutilide (applies to ibutilide) hepatic/renal

Moderate Potential Hazard, High plausibility. Applicable conditions: Liver Disease

The safety, effectiveness, and pharmacokinetics of ibutilide fumarate have not been established in patients with hepatic or renal dysfunction. It is unlikely that dosing adjustments would be necessary in these patients. Nonetheless, it should be administered cautiously in patients with abnormal liver or renal function, and monitoring is advised.

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.
