4. Clinical Particulars
4.1 Therapeutic Indications
Dobutamine is indicated for patients who require a positive inotropic support in the treatment of cardiac decompensation due to depressed contractility.
In cardiogenic shock characterised by heart failure with severe hypotension and in case of septic shock Dobutamine may be useful if added to dopamine in case of disturbed ventricular function, raised filling pressure of the ventricles and raised systemic resistance.
Dobutamine may also be used for detection of myocardial ischaemia and of viable myocardium within the scope of an echocardiographic examination (dobutamine stress echocardiography), if patients cannot undergo a period of exercise or if the exercise yields no information of value.
4.2 Posology And Method Of Administration
Dobutamine doses must be individually adjusted.
The required rate of infusion depends on the patient's response to therapy and the adverse reactions experienced.
Dosage in adults:
According to experience, the majority of patients respond to doses of 2.5-10 µg dobutamine/kg/min. In individual cases, doses up to 40 µg dobutamine/kg/min have been administered.
Dosage in children:
Doses of 1 to 15 µg dobutamine/kg/min have been administered. There is reason to believe that the minimum effective dosage for children is higher than for adults. Caution should be taken in administering high doses, because there is also reason to believe that the maximum tolerated dosage for children is lower than for adults. Most adverse reactions (tachycardia in particular) are observed when the dosage is 7.5 µg dobutamine/kg/min or above.
The required dose for children should be titrated in order to allow for the narrower “therapeutic window” in children.

Dobutamine stress echocardiography
Administration in stress echocardiography is undertaken by gradually increasing dobutamine infusion.
The most frequently applied dosage scheme starts with 5 µg/kg/min Dobutamine increased every 3 minutes to 10, 20, 30, 40 µg/kg/min until a diagnostic endpoint (see method and duration of application) is reached.
If no endpoint is reached atropine sulphate may be administered at 0.5 to 2 mg in divided doses of 0.25-0.5 mg at 1 minute intervals to increase the heart rate. Alternatively the infusion rate of dobutamine may be increased to 50 µg/kg/min.
The experience in children and adolescents is limited to the treatment of patients requiring positive inotropic support.
Method and duration of administration
Dobutamine 5 mg/ml (250 mg in 50 ml) ampoule or vial
Only for intravenous infusion (syringe pump). Dilution is not required.
Intravenous infusion of dobutamine is also possible after dilution with compatible infusion solutions such as: 5% glucose solution, 0.9% sodium chloride or 0.45% sodium chloride in 5% glucose solution. (For detailed information for dilution please see section 6.6.) Infusion solutions should be prepared immediately before use. (For information on shelf life, see section 6.3.)
Due to its short half-life, dobutamine must be administered as a continuous intravenous infusion.
The dose of dobutamine should be gradually reduced when discontinuing therapy.
The duration of treatment depends on the clinical requirements and is to be determined by the physician and should be as short as possible.
If dobutamine is administered continuously for more than 72 hours, tolerance may occur, requiring an increase in the dose.
During the course of dobutamine administration, heart rate, heart rhythm, blood pressure, diuresis and infusion rate should be closely monitored. Cardiac output, central venous pressure (CVP) and pulmonary capillary pressure (PCP) should be monitored if possible.
Dobutamine stress echocardiography
For detection of myocardial ischaemia and of viable myocardium dobutamine may only be administered by a physician with sufficient experience in conducting cardiology stress tests. Continuous monitoring of all wall areas via echocardiography, and ECG as well as control of blood pressure is necessary.
Monitoring devices as well as emergency medicines must be available (e.g. defibrillator, I.V. beta-blockers, nitrates, etc.) and staff trained in the resuscitation procedure must be present.
4.3 Contraindications
Dobutamine must not be used in the case of:
- known hypersensitivity to dobutamine or to any of the excipients,
- mechanical obstruction of ventricular filling and/or of outflow, such as pericardial tamponade, constrictive pericarditis, hypertrophic obstructive cardiomyopathy, severe aortic stenosis,
- hypovolaemic conditions.
Dobutamine stress echocardiography
Dobutamine must not be used for detection of myocardial ischaemia and of viable myocardium in case of:
- recent myocardial infarction (within the last 30 days),
- unstable angina pectoris,
- stenosis of the main left coronary artery,
- haemodynamically significant outflow obstruction of the left ventricle including hypertrophic obstructive cardiomyopathy,
- haemodynamically significant cardiac valvular defect,
- severe heart failure (NYHA III or IV),
- predisposition for or documented medical history of clinically significant or chronic arrhythmia, particularly recurrent persistent ventricular tachycardia,
- significant disturbance in conduction,
- acute pericarditis, myocarditis or endocarditis,
- aortic dissection,
- aortic aneurysm,
- poor sonographic imaging conditions,
- inadequately treated / controlled arterial hypertension,
- obstruction of ventricular filling (constrictive pericarditis, pericardial tamponade),
- hypovolaemia,
- previous experience of hypersensitivity to dobutamine.
Note:
If administering atropine, the respective contraindications have to be observed.
4.4 Special Warnings And Precautions For Use
Dobutamine must not be used for the treatment of patients with bronchial asthma who are hypersensitive to sulphites.
A local increase or decrease of coronary blood flow, which may have an impact on the myocardial oxygen demand, has been observed with dobutamine therapy. The clinical characteristics of patients with severe coronary heart disease may deteriorate, in particular if dobutamine therapy is accompanied by a considerable increase in the heart rate and/or blood pressure. Therefore, as with all positive inotropes, the decision to use dobutamine to treat patients with cardiac ischaemia must be made for each case individually.
Due to the risk of arrhythmias and the uncertainty about long term effects on myocardial dysfunction, inotropic agents, such as dobutamine, should be used with caution in the treatment of Acute Heart Failure (AHF).
As alterations in serum potassium level may occur, the potassium level should be monitored.
If dobutamine is administered continuously for more than 72 hours, tolerance phenomena (tachyphylaxis) may occur, requiring dosage increase.
Precipitous decreases in blood pressure (hypotension) have occasionally been described in association with dobutamine therapy. Decreasing the dose or discontinuing the infusion, typically results in rapid return of blood pressure to baseline values, but rarely intervention may be required and reversibility may not be immediate.
Dobutamine may interfere with HPLC determination of chloramphenicol.
Dobutamine stress echocardiography
Because of possible life-threatening complications, the administration of dobutamine for stress echocardiography should only be undertaken by a physician with sufficient personal experience of the use of dobutamine for this indication.
Dobutamine stress echocardiography must be discontinued if one of the following diagnostic endpoints occurs:
- reaching the age-predicted maximal heart rate [(220-age in years)x0.85],
- systolic blood pressure decrease greater than 20 mmHg,
- blood pressure increase above 220/120 mmHg,
- progressive symptoms (angina pectoris, dyspnoea, dizziness, ataxia),
- progressive arrhythmia (e.g. coupling, ventricular salvos),
- progressive conduction disturbances,
- recently developed wall motility disorders in more than 1 wall segment (16-segment model),
- increase of endsystolic volume,
- development of repolarisation abnormality (due to ischaemia horizontal or down sloping ST segment depression more than 0.2 mV at an interval of 80 (60) ms after the J point compared to baseline, progressive or monophasic ST segment elevation above 0.1 mV in patients without a previous myocardial infarction,
- reaching peak dose.
In the event of serious complications (see section 4.8) dobutamine stress echocardiography must be stopped immediately.
Dobutamine 5 mg/ml (250 mg in 50 ml)
This medicinal product contains 3.05 mg sodium per 1 ml of Dobutamine 5 mg/ml. This should be taken into consideration by patients on a controlled sodium diet.
Dobutamine contains sodium metabisulphite (E 223), which may rarely cause allergic reactions (hypersensitivity) and asthma-like symptoms (bronchospasm).
After termination of infusion, patients must be monitored until stabilised.
4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction
Via competitive receptor inhibition, the sympathomimetic effect of dobutamine can be reduced by simultaneous administration of a beta receptor blocker. In addition, the alpha agonistic effects may cause peripheral vasoconstriction with a consequent increase in blood pressure.
With simultaneous alpha-receptor blockade, the predominating beta-mimetic effects may cause tachycardia and peripheral vasodilatation.
Simultaneous administration of dobutamine and primarily venous acting vasodilators (e.g. nitrates, sodium nitroprusside) may cause a greater increase of cardiac output as well as a more pronounced decrease of peripheral resistance and ventricular filling pressure than administration of one of the individual substances alone.
Administering dobutamine to diabetic patients may cause increased insulin demand. In diabetic patients insulin levels should be checked when starting dobutamine therapy changing the rate of infusion and discontinuing the infusion. If necessary the insulin dose must be adjusted as required.
Simultaneous administration of high doses of dobutamine with ACE inhibitors (e.g. captopril) may cause an increase in cardiac output, accompanied by increased myocardial oxygen consumption. Chest pain and rhythm disturbances have been reported in this context.
Dobutamine combined with dopamine causes – depending on the dopamine dosage and in contrast to its sole administration – a more distinct increase of blood pressure as well as a decrease or no change of ventricular filling pressure.
Sodium metabisulphite is a very reactive compound. It must therefore be assumed that thiamine (vitamin B1) co-administered with the preparation is catabolised.
Caution should be exercised when administering dobutamine with inhaled anaesthetics, since concomitant use may increase the excitability of the myocardium and the risk of ventricular extrasystoles.
Dobutamine stress echocardiography
In the case of anti-anginal therapy, in particular heart rate lowering agents like beta-blockers, the ischaemic reaction to stress is less pronounced or may be nonexistent.
Therefore anti-anginal therapy may need to be withheld for 12 hours prior to dobutamine stress echocardiography.
When adding atropine at the highest titration level of dobutamine:
Due to the prolonged duration of the stress echocardiography protocol, the higher total dose of dobutamine and the simultaneous administration of atropine, there is an increased risk of adverse reactions.
4.6 Pregnancy And Lactation
As there is no adequate data on the safety of dobutamine in human pregnancy and it is not known whether dobutamine crosses the placenta, dobutamine should not be used during pregnancy unless potential benefits outweigh the potential risks to the foetus and there are no safer therapeutic alternatives.
It is not known, whether dobutamine is excreted in breast milk, so caution should be exercised. If treatment with dobutamine is required for the mother during lactation, breast feeding should be discontinued for the duration of treatment.

4.9 Overdose
Symptoms of overdose
Symptoms are generally caused by excessive stimulation of beta-receptors. Symptoms may include nausea, vomiting, anorexia, tremor, anxiety, palpitations, headache, anginal pain and unspecific chest pain. The positive inotropic and chronotropic cardiac effects may cause hypertension, supraventricular/ventricular arrhythmia and even ventricular fibrillation as well as myocardial ischaemia. Hypotension may occur due to peripheral vasodilatation.
Treatment of overdose
Dobutamine is metabolised rapidly and has a short duration of effect (half-life 2 - 3 minutes).
In case of overdose, administration of dobutamine should be terminated. If necessary, resuscitation procedures must be carried out immediately. Under conditions of intensive care, vital parameters must be monitored and corrected if necessary. Balanced levels of blood gases and serum electrolytes must be maintained.
Severe ventricular arrhythmias can be treated with administration of lidocaine or a beta blocker (e. g. propranolol).
Angina pectoris should be treated with a sublingually administrated nitrate or possibly a short-acting, I.V. beta blocker (e.g. esmolol).
In case of a hypertensive reaction, dose reduction or termination of the infusion is usually sufficient.
With oral administration, the quantity absorbed from the mouth or gastrointestinal tract is unpredictable. In case of accidental oral administration, resorption may be reduced by administration of activated charcoal, which is often more effective than administration of emetics or performing gastric lavage.
The benefit of forced diuresis, peritoneal dialysis, haemodialysis or haemoperfusion via activated charcoal has not been demonstrated for cases of dobutamine overdosage.
Dobutamine stress echocardiography
If applying one of the common dosage schemes, toxic doses are not reached, not even cumulatively. In case of severe complications during diagnostic administration of dobutamine, the infusion must be terminated at once and sufficient oxygen supply and ventilation must be guaranteed. Treatment of angina pectoris should be performed with an intravenous beta-blocker with a very short-acting effect. Angina pectoris may also be treated with a sublingually administered nitrate, if necessary. Class I and III antiarrhythmics must not be administrated.
5. Pharmacological Properties
5.1 Pharmacodynamic Properties
Pharmacotherapeutic group: Adrenergic and dopaminergic agents
ATC Code: C01CA07
Dobutamine is a synthetic, sympathomimetic amine, structurally related to isoproterenol and dopamine, and is administered as racemate. The positive inotropic effect is primarily based on the agonistic effect on cardiac beta1-receptors but also on cardiac alpha1-receptors; which leads to increased contractility with an increase in stroke volume and cardiac output. Dobutamine also has an agonistic effect on peripheral beta2- receptors and to a smaller extent on peripheral alpha2-receptors. In accordance with the pharmacological profile, positive chronotropic effects occur as well as effects on the peripheral vascular system. These however, are less pronounced than the effects of other catecholamines. The haemodynamic effects are dose-dependent. The cardiac output increases primarily due to an increase in the stroke volume; an increase in the heart rate is observed particularly with higher dosages. There is a reduction in left ventricular filling pressure and systemic vascular resistance. With higher doses, there is also a reduction in the pulmonary resistance. Occasionally an insignificant increase of the systemic vascular resistance can be observed. The volume increase due to an increase of the cardiac output is thought to be the reason for the blood pressure elevation. Dobutamine acts directly, independent from synaptic catecholamine concentrations, does not act at the dopamine receptor site, and – unlike dopamine – has no impact on the release of endogenous noradrenaline (norepinephrine).
There is a decrease of recovery time of sinus node and the A-V conduction time. Dobutamine may cause a tendency towards arrhythmia. When administered non-stop for more than 72 hours, tolerance phenomena were observed. Dobutamine impacts the functions of thrombocytes. Like all other inotropic substances, dobutamine increases myocardial oxygen demand. Via reduction of the pulmonary vascular resistance and the hyperperfusion even of hypoventilated alveolar areas (formation of a pulmonary “Shunt”) a relatively reduced oxygen supply may occur in some cases. The increase in cardiac output and the resulting increase in coronary blood flow usually compensate these effects and cause – compared with other positive inotropic substances – a favourable oxygen supply/demand ratio.
Dobutamine is indicated for patients who require positive inotropic support in the treatment of cardiac decompensation due to depressed contractility resulting either from organic heart disease or from cardiac surgical procedures, especially when a low cardiac output is associated with raised pulmonary capillary pressure.
In cases of heart failure accompanied by acute or chronic myocardial ischaemia, administration should be performed in a manner to prevent considerable increase in heart rate or blood pressure; otherwise, particularly in patients with a relatively good ventricular function, increase of ischaemia cannot be excluded.
There are only limited data with regard to clinical outcome including long-term morbidity and mortality. So far, no data exists to support a beneficial long-term effect on morbidity and mortality.
Dobutamine has no direct dopaminergic effect on renal perfusion.
Dobutamine stress echocardiography
Ischaemic diagnostic: Due to the positive inotropic testing and in particular due to the positive chronotropic effects under dobutamine stress, the myocardial oxygen (and substrate) demand increases. With a pre-existing coronary artery stenosis, an insufficient increase of coronary blood flow leads to local hypoperfusion, which can be demonstrated on the echocardiogram in the form of a newly developed myocardial wall motility disorder in the respective segment.
Viability diagnostic: Viable myocardium, which is hypokinetic or akinetic (due to stunning, hibernation) on the echocardiogram, has a contractile functional reserve. This contractile functional reserve is particularly stimulated by the positive inotropic effects during dobutamine stress testing at lower doses (5-20 µg/kg/min). An improvement of the systolic contractility, i.e. increase of wall motility in the respective segment, can be shown on the echocardiogram.
5.2 Pharmacokinetic Properties
Onset of action is 1 - 2 minutes after the start of infusion; during continuing infusion, steady-state plasma levels are only reached after 10 - 12 minutes. Steady-state plasma levels increase dose-dependently linearly to the infusion rate. Half-life is 2 - 3 minutes, distribution volume is 0.2 l/kg, plasma clearance is not dependent on cardiac output and is 2.4 l/min/m2. Dobutamine is mainly metabolised in the tissue and liver. It is mainly metabolised to conjugated glucuronides as well as the pharmacologically inactive 3-O-methyldobutamine. The metabolites are mainly excreted in urine (more than 2/3 of the dose), and to a lesser extent in bile.
5.3 Preclinical Safety Data
Preclinical data reveal no special hazard for humans based on conventional studies of safety pharmacology and repeated dose toxicity. There are no studies concerning the mutagenic and carcinogenic potential of dobutamine. In view of the vital indications and the short duration of treatment these studies appear of minor relevance. Studies in rats and rabbits revealed no evidence of a teratogenic effect. An impairment of implantation and pre- and postnatal growth retardations were observed in rats at doses toxic to mothers. No influence on fertility was seen in rats.
