A » Beta-blockers work by blocking the effects of adrenaline on your heart. They bind to beta-receptors in heart cells, slowing the heart rate and reducing blood pressure, which helps decrease the heart's workload. This makes them effective for treating conditions like hypertension, angina, and certain arrhythmias. By calming the heart, beta-blockers can also be beneficial in managing anxiety symptoms and improving overall cardiovascular health.

A »Beta-blockers work by blocking the action of epinephrine (adrenaline) and norepinephrine (noradrenaline) on beta receptors in the heart, reducing heart rate and contractility. For example, propranolol blocks beta-1 receptors, decreasing heart rate and blood pressure, making it useful for treating hypertension and angina.
