Acute aortic dissection is a life-threatening emergency with a mortality rate that can increase by 1-2% per hour if left untreated. A critical component of the initial stabilization is determining **what vasopressors are used for aortic dissection** and controlling hemodynamics to reduce stress on the weakened aortic wall. This medical management is crucial for improving patient outcomes and buying time for definitive surgical or endovascular treatment.

Hypertensive emergencies are medical crises marked by severely elevated blood pressure, typically systolic blood pressure > 180 mmHg or diastolic blood pressure > 120 mmHg, coupled with acute, life-threatening organ damage. These situations require immediate intervention with intravenous medications to prevent complications like stroke or heart failure. This guide explains what IV drugs are used for hypertension in these critical care scenarios.

It's estimated that the number of people with hypertension worldwide will rise to over 1.56 billion by 2025 [1.9.1]. In managing this condition, a key question is: **why is labetalol preferred** for specific, critical situations like hypertensive emergencies and use during pregnancy? [1.5.1]

Nicardipine, a second-generation dihydropyridine calcium channel blocker, is primarily used to treat hypertension and stable angina pectoris. The purpose of nicardipine is to relax blood vessels, decreasing the heart's workload and increasing blood flow to the heart and other organs.

Hypertensive emergencies affect an estimated 1–2% of hypertensive patients and require immediate, individualized treatment with intravenous agents to prevent or limit end-organ damage. The decision of whether **is esmolol better than nicardipine for hypertensive emergency** depends critically on the patient's specific clinical context, as each drug targets a different physiological mechanism.

According to a study published in *Hypertensive Emergency in Aortic Dissection*, both esmolol and labetalol are used for hemodynamic control. Choosing **when to use esmolol vs labetalol** is a critical decision in acute care, dictated by their differing mechanisms, pharmacokinetics, and patient-specific needs.

Labetalol is a versatile antihypertensive agent used to treat severe hypertension, including in pregnancy, with an onset of action typically within 2 to 5 minutes following IV administration. Understanding **how to give labetalol injection** safely is crucial for achieving rapid and controlled blood pressure reduction in urgent situations.

Over 3,000 patients in a recent large study received intravenous (IV) nicardipine for blood pressure control in acute stroke. Knowing **how does IV nicardipine work** is crucial, as it is a potent, titratable, and effective medication used for the short-term treatment of hypertensive emergencies.

Cardene I.V. (nicardipine) is a potent vasodilator that acts rapidly, with blood pressure beginning to fall within minutes of starting the infusion. This rapid action is what makes the onset of action of cardene IV so critical in acute settings, such as hypertensive emergencies and perioperative hypertension.

With an extremely short initial phase half-life of just one minute, CLEVIPREX (clevidipine) offers rapid and precise blood pressure reduction for critically ill patients. This article explains what does CLEVIPREX do and how its unique pharmacological profile addresses severe hypertension in controlled clinical settings.
