Nadolol

Nadolol, sold under the brand name Corgard among others, is a medication used to treat high blood pressure, heart pain, atrial fibrillation, and some inherited arrhythmic syndromes. It has also been used to prevent migraine headaches and complications of cirrhosis. It is taken orally. Common side effects include dizziness, feeling tired, a slow heart rate, and Raynaud syndrome. Serious side effects may include heart failure and bronchospasm. Its use in pregnancy and breastfeeding is of unclear safety. It is a non-selective beta blocker and works by blocking β1-adrenergic receptors in the heart and β2-adrenergic receptors in blood vessels. Nadolol was patented in 1970 and came into medical use in 1978. It is available as a generic medication. In 2020, it was the 340th most commonly prescribed medication in the United States, with more than 700 thousand prescriptions.
