What Is The Difference Between Levophed And Dopamine
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
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

They can be used concurrently for treatment of certain heart conditions. Ask your dr. ...Read moreSee 1 more doctor answer
Catecholamines: These are both catecholamines, synthesized from the Amino Acid tyrosine. Norepinephrine (ne) acts mainly in an area of your brainstem called the locus coeruleus -- triggering the stress response. Ne is also involved in pain, cognition, mood, emotions, movement and blood pressure. Dopamine is involved in regulating mood, pleasure, delusions, psychosis and drug abuse -- and more. ...Read more
First realize: the doctors are slightly making this up. In tests of whether matching drugs to symptoms worked... didn't work. Serotonin run systems involve sleep/eating/anxiety dopamine run systems involve pleasure. The only solid data is that drugs of abuse definitely activate the dopamine. Cocaine/meth dealers/designer drug dealers have better luck. but then, have more money for Research ...Read more
