Is dopamine similar to dobutamine?

Yes and no. They are both catecholamines, a specific type of chemical class. In the body, there are different type of receptors in tissues which bind catechols with different effects. Dopamine and doubtamine have different affinities for different receptors and thus can have different effects. Kind of like different types of baking sugars...They are all sugars but are used for special purposes and functions.
No. Hello bigflow-- no - Dopamine is very different than Dobutamine and they are used differently and for different indications -.

When should we choose dopamine over dobutamine in treating congestive cardiac failure?

Low blood pressure. If the blood pressure is low in CHF , Dopamine is better at raising it. Read more...
Sometimes use both. Dopamine has more affect on blood pressure (raises it). Dobutamine increases heart (myocardial) contractility so it makes the heart muscle beat stronger and subsequently increases cardiac output. They are often used together for people with heart failure and low bp. Read more...

What are the differences between levophed, (norepinephrine) dopamine and dobutamine?

Receptors. These three medications are used to support the heart and cardiovascular system ie. blood pressure and heart rate. They are known as sympathomimetics and have a similar response to what you would think of as adrenaline. Each has variable effect on either heart rate, heart function (in terms of strength of 'squeeze') and on blood vessels which would translate to higher blood pressure. Read more...

I was wondering what are the differences of levophed, (norepinephrine) dopamine and dobutamine in terms of their action?

You Asked for It---- Dobutamine- direct b1 receptor stimulant or agonist in the sympathetic nervous system. Levophed- vasoconstrictor peripherally (alpha adrenergic effects) and beta adrenergic stimulant at the level of the heart and coronary vessels dopamine- dual b1 and Alpha adrenergic effects. Useful in hypovolemic shock because of conservancy of renal blood flow. Also, works centrally in other complex ways. Read more...

Can you explain the differences between levophed, (norepinephrine) dopamine, and dobutamine?

Alters physiology. These are very simple answers to a complex question. Levophed (norepinephrine) increases blood pressure; Dopamine increases heart rate, blood pressure and cardiac function (contractility); Dobutamine increases cardiac contractility and heart rate. Read more...
Pressors & inotropes. Levophed (norepinephrine) causes blood vessels to constrict & is mainly used to increase blood pressure (pressor). Dobutamine helps the heart contract more forcefully & increase cardiac output (inotrope); it also can cause the blood vessels to dilate. Dobutamine is both a pressor & an inotrope--it makes blood vessels to constrict, & it increases cardiac output by causing the heart to beat faster & stronger. Read more...
