What Is The Difference Between 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
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 more
Incomparable: These are numerous, due to the fact that each of this drugs represents 3 different classes of medications: Lidocaine is a na (sodium) channel blocker for local anesthesia and arrhythmia, Dopamine is an inotrope (stimulates heart) and Atropine counteracts acetylcholine, a mediator in autonomous nervous system. They can be used concurrently for treatment of certain heart conditions. Ask your dr. ...Read more
Drug comparison: These three drugs are completely different drugs in different classes and with different side effects. They aren't even related to one another. ...Read more
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
Drugs for Heart Test: Chemical stress tests are used to diagnose heart artery blockage in people who cannot treadmill exercise. Persantine is injected IV and dilates normal blood vessels more than abnormal ones causing an ischemic defect on a nuclear image. Dobutamine is injected IV and increases the heart rate and contractility with muscle fed by a blocked artery not responding as well as normal muscle. ...Read more
What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.
Nuclear/ Echo stress: Lexiscan stress generally performed with nuclear isotope, which shows blood circulation (perfusion), comparing with medication lexiscan (stressing heart) and at rest. Dobutamine echo we are looking at wallmotion of heart with medication dobutamine (stressing heart)and at rest to see they show any differences to detect blockages ...Read more
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

What is the difference of a maoi and cocaine in terms of what it does to your brain? It looks like they both increase dopamine. :\
I want to boost dopamine level. So what's the difference among the three supplement : L Tyrosine, L-Dopa (Mucuna) and L-Phenylalanine?
I know serotonin and dopamine are the main "happy chemicals" in your brain. What is the difference in the feelings/types of happiness they cause?
Calm vs. Excited: The role of neurotransmitters in feelings is complex, but serotonin is involved in a sense of calm joy as from meditation or marijuana, whereas dopamine is related to a state of excitement- sometimes called the sex, drugs & rock'n'roll neurotransmitter, as from cocaine. Deficiencies or excess of each creates problems. See http://www. Buzzle. Com/articles/neurotransmitters-and-their-functions. Html ...Read more
Pleasurable: Pleasurable activities, foods, exercises, images, drinks (careful, I don t mean necessarily "those"...), even sex. Those things you enjoy the most, increase your dopaminergic activity. Wherever your passion is, like my brother says. That is in general. Now, in presence of a disease (like parkinsons), the whole mechanism lacks enough neurotransmitter to make this ideas effective. Consult your dr. ...Read more
The definition of a: Syndrome is "a collection of signs & symptoms that are clearly associated with a disease or disorder." To date, there is no scientifically or medically verified diagnosis of (or treatment for) "dopamine deficiency syndrome." There's no specific test for measuring dopamine levels. This answer may disappoint you but it's the only science-based answer I can give. Dr. Anne. ...Read more
Dopamine: Levels can drop if your iron level is low as iron is a cofactor for the enzyme Tyrosine Hydroxylase which is needed to make Dopamine. So I suggest you have your iron level checked first. There are a whole bunch of medications that affect Dopamine levels (in either direction) As a next step, I suggest you discuss this with a PCP who knows your situation well. ...Read more
I was told my son produces too much dopamine. Is there a way to test this? What are the symptoms of that?
How was this figured: I think there may be a miscommunication between you and the doctor. Although there are diseases with too little dopamine, i.e. Parkinson disease, I have never heard of a condition where we say there is too much dopamine. Certainly this isn't something that could be measured. I suppose theoretically there could be hallucinations or impulsiveness. ...Read more
Adaptogen: Classically considered an adaptogen, which means it supports many different appropriate reactions in a system that are protective or adaptive, it is thought to impact all the monoamines, of which Dopamine is one. It is claimed to increase impact of Dopamine responses possibly more than actually directly increasing levels, but that is controversial. ...Read more
Nobody knows: You can't measure dopamine levels clinically, and the amounts that are present are so tiny, that differences that may be clinically significant would not be noticeable. The biology is not what is important, it is the sociology and psychology of the problem. You have anger and anxiety but are using testosterone and you are 17??? This is self-destructive and you need counseling. You will do damage ...Read more
