Answer

Answer

Labetalol, an alpha- and beta-blocking agent, has proven to be quite beneficial in the treatment of patients with hypertensive emergencies. Labetalol is particularly preferred in patients with acute dissection and those with end-stage renal disease. Boluses of 10-20 mg may be administered, or the drug may be infused at 1 mg/min until the desired BP is obtained. Once an adequate BP level is obtained, oral hypertensive therapy should be initiated, and patients are gradually weaned from parenteral agents.
