In which conditions is Labetalol indicated?

• A. Hypertensive crisis and asthma
• B. Hypertensive crisis and second line agent for SVT
• C. Acute heart failure and shock
• D. Chronic hypertension only

Answer: (B)

Labetalol is particularly indicated for managing hypertensive crises due to its ability to rapidly lower blood pressure through a combination of alpha and beta-adrenergic receptor blockade. This dual action makes it effective in acute settings where immediate control of hypertension is necessary. Additionally, it serves as a second-line agent for supraventricular tachycardia (SVT), where it helps to reduce heart rate and improve cardiac output without causing significant bronchospasm, making it safer in patients with reactive airway conditions. In contrast, while Labetalol may be considered in some cases of acute heart failure and shock, these conditions typically require more specific therapies to stabilize the patient, such as inotropic support or vasopressors. Also, in chronic hypertension management, Labetalol can be used but is not limited solely to that context; its versatility in acute scenarios highlights its role in hypertensive crises and specific arrhythmic interventions.
