Dopamine

Dopamine is a medication and naturally occurring neurotransmitter used to support blood pressure, heart function, and organ perfusion in critical care settings.

What is it used for?
Dopamine is prescribed for the treatment of acute circulatory failure, such as shock, severe hypotension, or low cardiac output, particularly when these conditions threaten blood flow to vital organs (e.g. kidneys, brain). It is administered intravenously and used exclusively in hospital or intensive care settings with close monitoring.

How does it work?
Dopamine acts on different receptors depending on the dose:

• At low doses, it stimulates dopamine receptors, improving blood flow to the kidneys and other organs.
  
• At moderate doses, it stimulates beta-1 adrenergic receptors, increasing heart contractility and cardiac output.
  
• At higher doses, it activates alpha-adrenergic receptors, causing vasoconstriction and raising blood pressure.
  

Always use this medicine as prescribed by a healthcare professional.
