Dobutamine: Brands, Price & Uses in Bangladesh

Dobutamine is a synthetic catecholamine used as an intravenous inotropic agent. Its evidence-based uses are:

Established / FDA-approved use

• Short-term treatment of cardiac decompensation due to depressed myocardial contractility, arising from organic heart disease (e.g. decompensated heart failure) or following cardiac surgery.

Guideline-supported / adjunct uses

• Cardiogenic shock and low-cardiac-output states, typically as an adjunct alongside fluid resuscitation, vasopressors, and treatment of the underlying cause, under intensive/critical care monitoring.
• In atrial fibrillation with rapid ventricular response, a digitalis preparation should be given before starting Dobutamine because it can enhance atrioventricular conduction.

Off-label / diagnostic use (commonly used, label-recognized in practice)

• Pharmacologic stress testing (dobutamine stress echocardiography) in patients who cannot exercise adequately, to evaluate for coronary artery disease or myocardial viability. This is a widely used, well-established off-label application performed under continuous cardiac monitoring.

Dobutamine is not indicated for chronic oral or long-term outpatient use; it is administered by continuous intravenous infusion in a monitored setting.

Route

Dobutamine is given only by continuous intravenous infusion using an infusion pump, after dilution; it is never given orally, intramuscularly, or as a bolus.

Preparation

The concentrate must be diluted in at least 50 mL of a compatible intravenous fluid (e.g. 5% Dextrose Injection, 0.9% Sodium Chloride Injection, or Lactated Ringer's Injection) before administration.

Pediatric dose

Safety and effectiveness of Dobutamine in pediatric patients have not been formally established (see Use in Special Populations); when used in neonatal/pediatric intensive care, weight-based mcg/kg/min dosing similar to adults is used under specialist supervision.

Renal/hepatic impairment

No well-established dose adjustment is defined for renal or hepatic impairment; use with close hemodynamic monitoring in these patients (see Precautions).

The most common adverse effects of Dobutamine are cardiovascular and dose-related.

• Common: Increased heart rate, increased systolic blood pressure, palpitations, nausea, headache, anginal or chest pain, shortness of breath.
• Cardiac: Ventricular ectopic beats (in about 5% of patients), marked tachycardia, and rarely ventricular tachycardia or other arrhythmias; precipitous drops in blood pressure have also been reported, usually reversible with dose reduction.
• Local: Phlebitis at the infusion site; rare cutaneous necrosis with extravasation.
• Other: Mild reduction in serum potassium; occasional hypersensitivity-type reactions (rash, fever, eosinophilia, bronchospasm), related in part to the sodium metabisulfite contained in some formulations, particularly in patients with asthma or sulfite sensitivity.
