vasopressor agents

Vasopressor agents are medications used by healthcare providers to raise blood pressure in critically ill patients with low blood pressure (hypotension). They work by constricting blood vessels, which increases the resistance against which the heart pumps, ultimately helping to restore normal blood flow to vital organs like the brain and heart. Common vasopressors include medications like norepinephrine and dopamine. They are typically administered in hospital settings, especially in emergencies or intensive care, to stabilize patients whose blood pressure drops dangerously low due to conditions such as shock or severe infections.
