Labetalol is part of a class of drugs known as antihypertensives, specifically a beta-blocker. Beta-blockers work by binding to the β-adrenergic receptors found on the heart and blood vessels. This causes the heart to beat slower and reduces systemic blood pressure.
Unlike most other beta-blockers, labetalol also binds to α1-adrenergic receptors which have a more selective action on blood vessels, leading to a greater reduction in blood pressure. Because labetalol is a non-selective beta-blocker, it also binds to the β-adrenergic receptors found in the lungs which may cause symptoms such as cough.
Labetalol is mainly indicated to treat the following conditions:
Labetalol is available as an oral tablet and solution for injection in vials. The oral tablet should be taken by mouth without chewing or crushing it. The IV solution should be administered by a licensed health professional in a clinical setting.

Beta-blockers, including labetalol, are associated with an increased risk of hypotension and cough. This risk is further increased in older patients usually over 60 years of age, regular alcohol drinkers, and those with respiratory conditions.
Some groups of people with conditions like asthma may experience an exacerbation of symptoms after using beta-blockers.
