Labetalol works on both alpha and beta receptors in the heart to lower blood pressure and slow heart rate. Its alpha blockade action prevents epinephrine and norepinephrine from interacting with alpha receptors which decreases vascular resistance, increases vasodilation, and decreases blood pressure overall.

What is labetalol used for?

As labetalol is typically used to treat acute hypertension, whether it presents in the emergency department or an outpatient clinic, an interprofessional team approach and effective communication are essential for quality patient care. This interprofessional team can include specialists, other clinicians (MDs, DOs, PAs, NPs), nursing staff, and pharmacists. In the emergency department, swift intake and triage by the nurse or medical technician to identify a patient with dangerously elevated blood pressure and quickly but effectively convey the critical information to a physician or provider are necessary. If hospital admission is warranted, communicating the crucial details of the patient's presentation, medical history, and the treatment and current medical workup that have been completed are important, so time and resources are not wasted on repeating tests and exams. Utilizing an interprofessional team methodology that employs open communication between all team members and coordinated activity will improve patient outcomes and fewer adverse effects, particularly in hypertensive emergencies. [Level 5]

What is intravenous labetalol used for?

Intravenous labetalol in the treatment of severe hypertension and hypertensive emergencies.

Is labetalol safe for hypotension?

Overall, labetalol is usually well tolerated. Most adverse effects are typically mild and transient. As previously described above, symptomatic postural hypotension is a potential occurrence if patients are tilted or allowed to change positions from the supine or seated position to standing too quickly. This is especially important in the post-operative period (PACU or the ward) when managing a hypertensive patient with labetalol who can otherwise ambulate to the bathroom. Increased sweating, as well as flushing, have been reported with the use of labetalol. It seems the incidence of adverse reactions after administering labetalol seems to be dose-dependent. [6]

What is the best treatment for a beta blocker overdose?

Supportive care and close monitoring are the staples of treatment for an overdose of beta-blockers with the addition of glucagon for severe refractory hypotension and bradycardia.

Is labetalol FDA approved?

The FDA-approved indication for labetalol is the treatment of arterial hypertension, which ranges from acute hypertensive crises (urgent/emergency) to stable chronic hypertension. Labetalol in clinical practice has several common off-label uses that include acute hypertension in pregnancy and hypertension associated with acute ischemic stroke, and intracranial hemorrhage, including subarachnoid hemorrhage. Today, labetalol is usually reserved for the acute management of hypertensive crises.

Can beta blockers cause claudication?

As with all beta-blockers, labetalol has negative inotropic effects and has the potential to cause acute left ventricular failure if given in sufficiently large enough doses to those patients who have impaired function of the left ventricle. All beta-blockers can exacerbate intermittent claudication and Raynaud phenomenon in patients with coexisting peripheral vascular disease. Another important consideration for anesthesia providers in the perioperative period is that non-selective beta-blockers that interact with beat receptors can result in bronchospasm in patients with a history of asthma or chronic obstructive pulmonary disease due to antagonism of beta receptors. Sudden withdrawal of beta-blockers can result in increased sensitivity to catecholamines. This upregulation can lead to tachyarrhythmias, acute hypertensive crises, and palpitations, although this is more common with chronic use. [7]

What is a bolus of lbetalol?

Labetalol is a combined α and β-blocker that can be given as a continuous infusion or as an IV bolus . It lowers systemic vascular resistance with minimal effect on CO.123 It provides nonselective β-adrenergic blockade, which reduces reflex tachycardia and increased cardiac contractility that may be seen with vasodilators. β 2 -Adrenergic blockade would increase SVR, but this effect is counterbalanced by α-adrenergic blockade, which is selective for the α 1 -receptor, resulting in vasodilation. The α-to-β blocking ratio of the oral preparation is 1:3, whereas it is 1:7 for the IV form. 97 Labetalol is therefore most useful in situations where HTN is produced by excessive sympathetic nervous system activity. Labetalol has an onset of action of 2 to 5 minutes with a peak at 5 to 15 minutes, and it can last up to 4 hours. It is metabolized in the liver through glucuronide conjugation and excreted in the urine, bile, and stool. 124

What is labetalol used for?

Labetalol is a combined α- and β-adrenergic receptor blocker that currently is approved for both oral and intravenous use in the treatment of hypertension. Labetalol lowers blood pressure by decreasing systemic vascular resistance by α1 -blockade and at the same time counteracts the reflex tachycardia from vasodilation through its β-blocker effect. 28,29 Labetalol reduces peripheral vascular resistance while maintaining cerebral, renal, and coronary blood flow. Unlike other β-blockers, labetalol does not reduce cardiac output. When administered intravenously it has a rapid onset of action (2 to 5 minutes), with peak hypotensive effect occurring within 5 to 10 minutes and the effect lasting 2 to 4 hours. 30 The drug is metabolized primarily by the liver and has a plasma elimination half-life of approximately 5 hours. 28

What are the adverse effects of labetalol?
