What is the difference between dopamine and dobutamine?

What is the difference between dopamine and dobutamine?

Natural/synthetic: Dopamine is a naturally occuring catecholamine with numerous physiologic functions including neural transmission and BP regulation. Dobutamine is a synthetic drug used for testing and cardiac stimuation.

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

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.

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.

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.

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.

When should someone use dopamine and dobutamine?

Never: Those are serious and dangerous medications and should only be administered in an intensive care setting by a qualified physican.

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

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

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.

Please help! What is the difference between the effects of lidocaine, dopamine and atropine?

Please help! What is the difference between the effects of lidocaine, dopamine and atropine?

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.

Doctors, what is the difference between l-tyrosine and l-dopamine?

Tyrosine is: tyrosine is the precursor in the biochemical pathway for dopamine synthesis in the body.

What's the difference between the effects of lidocaine, dopamine and atropine?

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.

Is there difference between norepinephrine vs. Dopamine?

Is there difference between norepinephrine vs. Dopamine?

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.

What is the difference between persantine and dobutamine?

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.

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

What are the difference in low dopamine vs low seratonin symptoms?

What are the difference in low dopamine vs low seratonin symptoms?

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

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. :\

MAOi's: Maoi's inhibit oxidation of monoamines, which are histamines, catecholamines (dopamine, adrenaline, norepinephrine), tryptamines (serotonin & melatonin), & trace amines such as tyramine. Cocaine blocks the reabsorption of neurotransmitters such as 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 want to boost dopamine level. So what's the difference among the three supplement : L Tyrosine, L-Dopa (Mucuna) and L-Phenylalanine?

Amino acids: These are different amino acids your body can use to make other amino acids. Most people want to boost their dopamine level in the brain, it is not clear that taking supplements can do this. What is you goal, actually? It would be better to start there.

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?

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

Some docs on here said l-tyro can help w dopamine depletion from stims. Is this with stims or on off days from them? Daily? Would this b 2stimulating?

Follow the: Recommended dose on the label. Feel for yourself the effect. If it's too stimulating then decrease the dose. Tyrosine indeed increase the level of neurotransmitters like Dopamine and norepinephrine.
