title: Labetalol in hypertensive emergencies.
abstract: Labetalol, a combined alpha-blocking and beta-blocking agents, was administered by intravenous bolus to six severely hypertensive patients. The blood pressure response was unsatisfactory in every case. It is concluded that intravenous administration of labetalol is not useful in hypertensive emergencies which occur in patients who are already receiving other antihypertensive agents.
