Administration
Injectable Administration

Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit.
Premixed bags of dobutamine in 5% Dextrose Injection solutions may exhibit a pink color that, if present, will increase with time. This color change is due to slight oxidation of the drug, but there is no significant loss of potency. A sulfur dioxide odor may occur upon removal of the product from the overwrap container. This does not pose risk to the clinician or the patient.

Intravenous Administration

Dilution
Concentrate must be diluted with a compatible IV solution (e.g., 5% Dextrose Injection, 10% Dextrose Injection, 0.9% Sodium Chloride Injection, 5% Dextrose and 0.9% Sodium Chloride Injection, 5% Dextrose and 0.45% Sodium Chloride Injection, Lactated Ringer's Injection) prior to administration.[52045]
ASHP Recommended Standard Concentrations for Adult Continuous Infusions: 4,000 mcg/mL.[64020]
ASHP Recommended Standard Concentrations for Pediatric Continuous Infusions: 1,000 mcg/mL, 2,000 mcg/mL, or 4,000 mcg/mL.
Maximum concentration should not exceed 5,000 mcg/mL.[52045]
 
Continuous IV Infusion
Administer diluted solution by IV infusion using a controlled infusion device.[29561] [52045]
Infuse into a large vein whenever possible.[29561] [52045] [64934] May administer via peripheral IV.[64934]
Use caution to avoid inadvertent bolus administration or inadvertent interruption of the infusion, particularly during line changes, when flushing the line, or during syringe/bag changes.
Do not administer dobutamine simultaneously with solutions containing sodium bicarbonate or strong alkaline solutions (incompatible). Solutions containing dextrose should not be administered through the same administration set as blood, as this may cause pseudoagglutination or hemolysis.
Initiate infusion at a low rate and titrate every few minutes to reach the optimal dosage based on patient response. Dosage titration is guided by the patient's response, including systemic blood pressure, urine flow, frequency of ectopic activity, heart rate, and (whenever possible) measurements of cardiac output, central venous pressure, and/or pulmonary capillary wedge pressure.[29561] [52045]

Other Injectable Administration

Intraosseous Administration
NOTE: Dobutamine is not FDA-approved for intraosseous administration.
During cardiopulmonary resuscitation, the same dosage may be given via the intraosseous route if IV access is unsuccessful or not feasible.

Description

Parenteral direct-acting inotrope
Used for short-term treatment of patients with cardiac decompensation due to depressed contractility from organic heart disease or cardiac surgical procedures
Comparatively mild chronotropic, hypertensive, arrhythmogenic, and vasodilative effects

Dosage And Indications
For the short-term inotropic treatment of low output states caused by congestive heart failure, cardiogenic shock, septic shock†, or after cardiac surgery. Intravenous or Intraosseous† dosage Adults

0.5 to 1 mcg/kg/minute continuous IV infusion. Titrate every few minutes to clinical response.[29561] [32510] Usual dose: 2 to 20 mcg/kg/minute IV.[29561] [32359] [32510] [57101] Titrate dosage based on hemodynamic response, including systemic blood pressure, urine flow, frequency of ectopic activity, heart rate, and (whenever possible) measurements of cardiac output, central venous pressure, and/or pulmonary capillary wedge pressure.[29561] Infusion rates higher than 20 mcg/kg/minute may produce tachycardia or ventricular ectopy. On rare occasions, infusion rates up to 40 mcg/kg/minute IV have been required to obtain the desired clinical response.[29561] Septic shock guidelines suggest adding dobutamine to norepinephrine in patients with cardiac dysfunction with persistent hypoperfusion despite adequate volume status and arterial blood pressure. Heart failure guidelines suggest inotropic support until definitive therapy or resolution of acute precipitating problem to maintain systemic perfusion and preserve end-organ performance. Short-term, continuous IV inotropic support may be reasonable in hospitalized patients presenting with documented severe systolic dysfunction with low blood pressure and significantly depressed cardiac output. Consider long-term continuous IV inotropic support as palliative therapy for symptom control in patients with stage D heart failure refractory to optimal medical and device therapy who are awaiting mechanical circulatory support (MCS) or cardiac transplant or are not eligible for MCS or transplant.[57101] [62661]

Infants, Children, and Adolescents

0.5 to 1 mcg/kg/minute continuous IV/IO infusion. Titrate every few minutes to clinical response. Usual dose: 2 to 20 mcg/kg/minute.[29561] [43713] Infusion rates higher than 20 mcg/kg/minute may produce tachycardia or ventricular ectopy. On rare occasions, infusion rates up to 40 mcg/kg/minute have been required to obtain the desired clinical response.[29561]

Neonates

0.5 to 1 mcg/kg/minute continuous IV/IO infusion. Titrate every few minutes to clinical response. Usual dose: 2 to 20 mcg/kg/minute.[29561] [43713] Infusion rates higher than 20 mcg/kg/minute may produce tachycardia or ventricular ectopy. Because of variation in development, there is significant interpatient variability in response to dobutamine in neonates. Very preterm neonates are likely to have an attenuated reduction in systemic vascular resistance (SVR) compared to term neonates and, therefore, experience a more pronounced increase in blood pressure.[52072]

For use in coronary artery disease diagnosis† (i.e., dobutamine stress echocardiography†). Intravenous dosage Adults

5 mcg/kg/minute continuous IV infusion; titrate to 10, 20, 30, and 40 mcg/kg/minute continuous IV infusion at 3-minute intervals. Low dose dobutamine, with an initial dose of 2.5 mcg/kg/minute may facilitate recognition of myocardial viability in abnormal segments. Add atropine when target heart rate cannot be achieved with dobutamine alone. Dobutamine stress echocardiography is the preferred alternative test for evaluation of myocardial ischemia when a patient cannot exercise.

†Indicates off-label use

Dosing Considerations
Hepatic Impairment

Procarbazine: (Major) Because procarbazine exhibits some monoamine oxidase inhibitory (MAOI) activity, sympathomimetic drugs should be avoided. As with MAOIs, the use of a sympathomimetic drug with procarbazine may precipitate hypertensive crisis or other serious side effects. In the presence of MAOIs, drugs that cause release of norepinephrine induce severe cardiovascular and cerebrovascular responses. In general, do not use a sympathomimetic drug unless clinically necessary (e.g., medical emergencies, agents like dopamine) within the 14 days prior, during or 14 days after procarbazine therapy. If use is necessary within 2 weeks of the MAOI drug, in general the initial dose of the sympathomimetic agent must be greatly reduced. Patients should be counseled to avoid non-prescription (OTC) decongestants and other drug products, weight loss products, and energy supplements that contain sympathomimetic agents.

Although sympathomimetics are contraindicated for use with other non-selective monoamine oxidase inhibitors (MAOIs), hypertensive reactions generally are not expected to occur during concurrent use with rasagiline because of the selective monoamine oxidase-B (MAO-B) inhibition of rasagiline at manufacturer recommended doses. One case of elevated blood pressure has been reported in a patient during concurrent use of the recommended dose of rasagiline and ophthalmic tetrahydrozoline. One case of hypertensive crisis has been reported in a patient taking the recommended dose of another MAO-B inhibitor, selegiline, in combination with ephedrine. It should be noted that the MAO-B selectivity of rasagiline decreases in a dose-related manner as increases are made above the recommended daily dose and interactions with sympathomimetics may be more likely to occur at these higher doses.

Tirzepatide: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking incretin mimetics. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Tolcapone: (Moderate) Drugs known to be metabolized by catechol-O-methyltransferase (COMT), such as dobutamine, should be administered cautiously to patients receiving COMT inhibitors. Concomitant use may result in increased heart rates, possibly arrhythmias, and excessive changes in blood pressure.
Tranylcypromine: (Contraindicated) In general, sympathomimetics should be avoided in patients receiving MAOIs due to an increased risk of hypertensive crisis. This applies to sympathomimetics including stimulants for ADHD, narcolepsy or weight loss, nasal, oral, and ophthalmic decongestants and cold products, and respiratory sympathomimetics (e.g., beta agonist drugs). Some local anesthetics also contain a sympathomimetic (e.g., epinephrine). In general, medicines containing sympathomimetic agents should not be used concurrently with MAOIs or within 14 days before or after their use.
Treprostinil: (Major) Avoid use of sympathomimetic agents with treprostinil. Sympathomimetics counteract the medications used to stabilize pulmonary hypertension, including treprostinil. Sympathomimetics can increase blood pressure, increase heart rate, and may cause vasoconstriction resulting in chest pain and shortness of breath in these patients. Patients should be advised to avoid amphetamine drugs, decongestants (including nasal decongestants) and sympathomimetic anorexiants for weight loss, including dietary supplements. Intravenous vasopressors may be used in the emergency management of pulmonary hypertension patients when needed, but hemodynamic monitoring and careful monitoring of cardiac status are needed to avoid ischemia and other complications.
Triamterene; Hydrochlorothiazide, HCTZ: (Moderate) Sympathomimetics can antagonize the effects of antihypertensives such as metolazone when administered concomitantly.
Umeclidinium; Vilanterol: (Moderate) Administer sympathomimetics with caution with beta-agonists such as vilanterol. The cardiovascular effects of beta-2 agonists may be potentiated by concomitant use. Monitor the patient for tremors, nervousness, increased heart rate, or other additive side effects.
Valsartan; Hydrochlorothiazide, HCTZ: (Moderate) Sympathomimetics can antagonize the effects of antihypertensives such as metolazone when administered concomitantly.
Vasodilators: (Moderate) Use sympathomimetic agents with caution in patients receiving therapy for hypertension. Patients should be monitored to confirm that the desired antihypertensive effect is achieved. Sympathomimetics can increase blood pressure and heart rate, and antagonize the antihypertensive effects of vasodilators when administered concomitantly. Anginal pain may be induced when coronary insufficiency is present.

Mechanism Of Action

Dobutamine is a direct-acting sympathomimetic. It is primarily an agonist at beta1-adrenergic receptors, with minor beta2 and alpha1 stimulatory effects. Clinical actions reflect both beta agonism by the (+) isomer and the alpha agonism by the less potent (-) isomer. Agonism at the beta1-adrenergic receptor predominates and increases myocardial contractility and stroke volume with modest chronotropic effects, resulting in increased cardiac output. The inotropic effects are dose-dependent. Dobutamine's secondary hemodynamic effects include decreases in systemic vascular resistance (afterload) and ventricular filling pressure (preload). Systolic blood pressure is generally elevated as a consequence of increased stroke volume, although diastolic blood pressure and mean arterial pressure are usually unchanged with normal doses in normotensive patients. Increased myocardial contractility results in increased coronary blood flow and myocardial oxygen consumption. Dobutamine has minimal effect on pulmonary vascular resistance. Unlike dopamine, dobutamine does not affect dopaminergic receptors, nor does it cause release of norepinephrine from sympathetic nerve endings. Urinary output can increase, however, secondary to increased cardiac output. Electrophysiologically, dobutamine can facilitate AV nodal conduction, particularly in patients with concomitant atrial fibrillation.

Pharmacokinetics

Dobutamine is administered via continuous IV infusion. Onset of action occurs within 2 minutes, although peak pharmacodynamic activity can be delayed up to 10 minutes. The plasma half-life of dobutamine is about 2 minutes. The drug is metabolized in the liver enzymatically by catechol-O-methyltransferase and by glucuronidation to inactive metabolites. Excretion occurs mainly by the kidney as the metabolites and conjugates.

Pregnancy And Lactation
Pregnancy

Animal studies have revealed no fetal toxicities; however, no adequate or well-controlled studies have been conducted in pregnant women. Use dobutamine during pregnancy only when the expected benefits clearly outweigh the potential risks to the fetus.[29561] [32510]

It is not known if dobutamine is excreted in human breast milk. Because many drugs are excreted in human milk, use caution when administering dobutamine to a breast-feeding woman. If a mother requires dobutamine treatment, discontinue breast-feeding for the duration of dobutamine treatment.[52045]
