Clinical Trials:


Indications and Usage

Dobutamine in 5% Dextrose Injection, USP is indicated when parenteral therapy is necessary for inotropic support in the short-term treatment of cardiac decompensation due to depressed contractility resulting either from organic heart disease or from cardiac surgical procedures. Experience with intravenous dobutamine in controlled trials does not extend beyond 48 hours of repeated boluses and/or continuous infusions.Whether given orally, continuously intravenously, or intermittently intravenously, neither dobutamine nor any other cyclic-AMP-dependent inotrope has been shown in controlled trials to be safe or effective in the long-term treatment of congestive heart failure.

In controlled trials of chronic oral therapy with various such agents, symptoms were not consistently alleviated, and the cyclic-AMP-dependent inotropes were consistently associated with increased risks of hospitalization and death.

Patients with NYHA Class IV symptoms appeared to be at particular risk.
Congestive heart failure -- complication of heart diseases; defective cardiac filling and/or impaired contraction and emptying, resulting in the heart's inability to pump a sufficient amount of blood to meet the needs of the body tissues or to be able to do so only with an elevated filling pressure.

Symptoms -- An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.

Contraindications
Dobutamine in 5% Dextrose Injection, USP is contraindicated in patients with idiopathic hypertrophic subaortic stenosis and in patients who have shown previous manifestations of hypersensitivity to dobutamine.Dextrose solutions without electrolytes should not be administered simultaneously with blood through the same infusion set because of the possibility that pseudoagglutination of red cells may occur.
Asymmetric Septal Hypertrophy -- myocardial disease characterized by general increase in bulk of the myocardium due to an increase in cell volume; it is not due to tumor formation, nor to an increase in the number of cells; involving mainly the interventricular septum, interfering with left ventricular emptying.

Idiopathic hypertrophic subaortic stenosis --

Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.

Warnings

Increase in Heart Rate or Blood Pressure Dobutamine hydrochloride may cause a marked increase in heart rate or blood pressure, especially systolic pressure. Approximately 10% of adult patients in clinical studies have had rate increases of 30 beats/minute or more, and about 7.5% have had a 50-mm Hg or greater increase in systolic pressure.

Usually, reduction of dosage promptly reverses these effects.

Because dobutamine facilitates atrioventricular conduction, patients with atrial fibrillation are at risk of developing rapid ventricular response.

In patients who have atrial fibrillation with rapid ventricular response, a digitalis preparation should be used prior to institution of therapy with dobutamine.

Patients with pre-existing hypertension appear to face an increased risk of developing an exaggerated pressure response.Ectopic ActivityDobutamine may precipitate or exacerbate ventricular ectopic activity, but it rarely has caused ventricular tachycardia.HypersensitivityReactions suggestive of hypersensitivity associated with administration of Dobutamine in5% Dextrose Injection, USP, including skin rash, fever, eosinophilia, and bronchospasm, have been reported occasionally.Additive medications should not be delivered via this solution.Dobutamine in 5% Dextrose Injection, USP contains sodium bisulfite, a sulfite that may cause allergic-type reactions, including anaphylactic symptoms and life-threatening or less severe asthmatic episodes, in certain susceptible people.

The overall prevalence of sulfite sensitivity in the general population is unknown and probably low.

Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people.
