Used primarily as a vasopressor in the treatment of hypotension, particularly in surgical or shock-related conditions. It acts by stimulating alpha-adrenergic receptors, leading to vasoconstriction and increased blood pressure. Commonly administered in acute care settings where rapid correction of low blood pressure is required. Its effects are relatively short-acting, allowing for controlled management of hemodynamic stability. Often preferred when a fast onset and short duration of action are needed to avoid prolonged hypertension.
