Propranolol is a nonselective beta-blocker that blocks both beta-1 and beta-2 receptors, slowing heart rate and decreasing the heart's workload, which reduces blood pressure and oxygen demand. It's used to treat various conditions, including high blood pressure, angina, and cardiac arrhythmias, as well as to prevent migraines and tremors. Because it also blocks beta-2 receptors, it can cause side effects like bronchoconstriction, which can be dangerous for people with asthma.
