Vasoactive Agents
Vasoactive agents are medications that influence blood vessel tone, either narrowing (vasoconstrictors) or widening (vasodilators) them. They help regulate blood pressure and blood flow, especially in critical situations like shock or severe blood loss. For example, vasoconstrictors increase blood pressure by tightening blood vessels, ensuring vital organs receive enough blood. Conversely, vasodilators relax blood vessels, lowering blood pressure when it is too high. These drugs are essential in emergency and intensive care settings to maintain proper circulation and organ function.
