Labetalol
Labetalol is a medication used to treat high blood pressure and in long term management of angina. This includes essential hypertension, hypertensive emergencies, and hypertension of pregnancy. In essential hypertension it is generally less preferred than a number of other blood pressure medications. It can be given by mouth or by injection into a vein.
Common side effects include low blood pressure with standing, dizziness, feeling tired, and nausea. Serious side effects may include low blood pressure, liver problems, heart failure, and bronchospasm. Use appears safe in the latter part of pregnancy and it is not expected to cause problems during breastfeeding. It works by blocking the activation of β- and α-adrenergic receptors.
Labetalol was patented in 1966 and came into medical use in 1977. It is available as a generic medication. In 2023, it was the 232nd most commonly prescribed medication in the United States, with more than 1 million prescriptions.
Labetalol is effective in the management of hypertensive emergencies, postoperative hypertension, pheochromocytoma-associated hypertension, and rebound hypertension from beta blocker withdrawal.
It has a particular indication in the treatment of pregnancy-induced hypertension which is commonly associated with pre-eclampsia.
It is also used as an alternative in the treatment of severe hypertension.
Labetalol is useful in the treatment of acute cardiovascular toxicity (e.g. in overdose) caused by sympathomimetics like amphetamine, methamphetamine, cocaine, ephedrine, and pseudoephedrine. Other beta blockers are also used. However, the controversial yet possible phenomenon of "unopposed α-stimulation" with administration of selective beta blockers to block non-selective sympathomimetics potentially makes dual alpha-1 and beta blockers like labetalol and carvedilol more favorable for such purposes. The rate of unopposed α-stimulation with selective beta blockers has been reported to be 0.4%, whereas no cases of unopposed α-stimulation have been reported with dual alpha and beta blockers like labetalol.
Pregnancy: studies in lab animals showed no harm to the baby. However, a comparable well-controlled study has not been performed in pregnant women.
