What is the action of Dopamine Injection?
Dopamine Injection is a neurotransmitter found in some parts of the central nervous system and is a precursor to norepinephrine in noradrenergic neurons. Dopamine has positive chronotropic and inotropic effects on the myocardium, which raise heart rate and cardiac contractility.
What is Dopamine used for in an emergency?
Dopamine is a sympathomimetic agent used in emergency medicine and critical care to treat symptomatic bradycardia resistant to atropine and other therapies and to improve blood pressure (BP) in specified kinds of circulatory shock.
Why Dopamine is given IV?
Intravenous (IV) infusions of dopamine are administered. To enhance urine output and kidney blood flow, use a modest dosage of 1 to 5 mcg/kg/minute IV. Increases kidney blood flow, cardiac output and contractility, and heart rate at an intermediate dose of 5 to 15 mcg/kg/minute IV.
Is dopamine a drug?
Dopamine is a prescription drug that improves blood flow to the kidneys and relieves low blood pressure and poor cardiac output symptoms. Dopamine is a neurotransmitter that can be used alone or in combination with other medications. Dopamine is an inotropic agent, meaning that it promotes dopamine release in the brain.

Does dopamine affect heart rate?
Dopamine raised blood pressure, heart rate, and levels of epinephrine (E) and norepinephrine (NE) in the circulation. Dopamine agonists lower blood pressure by blocking sympathetic neuronal NE discharge and, to a lesser extent, increasing dopamine vascular receptors.
Is high dopamine good?
Too much dopamine — or too much dopamine concentrated in some parts of the brain but not enough in others — is associated with competitiveness, aggression, and poor impulse control. ADHD, binge eating, addiction, and gambling are among the disorders that can result from it.
