Dobutamine is a medication used in the treatment of cardiogenic shock (as a result of inadequate tissue perfusion) and severe heart failure. [2] [3] It may also be used in certain types of cardiac stress tests. [2] It is given by IV only, as an injection into a vein or intraosseous as a continuous infusion. [2]
Treatment typically involves uses of vasopressor, inotropes, fluid boluses, and introduction of resuscitation. [4] In case vasodilatory shock fails to respond to high doses of vasopressors (defined as ≥ 0.5 mg/kg/min norepinephrine-equivalent dose [ 7 ] ), meaning it's vasopressor-resistant and advances to being called refractory vasodilatory ...
Some substances do both (e.g. dopamine, dobutamine). If low blood pressure is due to blood loss, then preparations increasing volume of blood circulation—plasma-substituting solutions such as colloid and crystalloid solutions (salt solutions) [1] —will raise the blood pressure without any direct vasopressor activity.
Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body's organs due to the dysfunction of the heart. Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness. People may also have a severely low blood pressure and heart rate.
Dobutamine – The effects of beta-agonists such as dobutamine can be reversed by administering beta-blockers such as propranolol. Regadenoson or dobutamine is often used in patients with severe reactive airway disease (asthma or COPD) as adenosine and dipyridamole can cause acute exacerbation of these conditions. If the patient's asthma is ...

Specifically, dobutamine selectively binds to β1 receptors located on the surface of specialised cardiac muscle cells. [16] Relative to β2 receptors, β1 is the predominant type in terms of quantity and function within the heart.
