Levophed Dopamine 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
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 moreSee 1 more doctor answer
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
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. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer

Dopamine production: There is no proven way to increase dopamine. Ingested Dopamine is broken down in the stomach and small intesting (unless combined with a special medication...Carbidopa, for example in the medicine given to parkinson's patients carbidopa/levodopa). It can be given intravenously, which is done sometimes to help increase blood pressure. See also: http://en.Wikipedia.Org/wiki/dopamine. ...Read more
Wise guy answer: I know this may seem like a wiseguy type of an answer to you but truthfully it is exactly to your point. The patient is given dopamine in the form of carbidopa levodopa usually and we see if the dystonia gets better. Hence, the name "dopamine responsive dystonia."some things in medicine are just that easy. Want to become a doctor? Cheers! ...Read more
No: Truly homeopathic "medications" are made by repeated dilutions, so that the ingredient is not really there anymore (just the "essence" of it remains). That means there is no active ingredient left to antagonize dopamine. However, that also implies that the homeopathic "medicine" should be pretty harmless, unless some other non-homeopathic ingredient (such as some other chemical) was added. ...Read more
