A » Beta-blockers work by blocking the effects of adrenaline on beta receptors in the heart, leading to a decrease in heart rate and blood pressure. This helps manage conditions like hypertension, angina, and anxiety. By reducing the heart's workload and oxygen demand, they can also prevent heart attacks and provide a calming effect, making them versatile in treating cardiovascular and stress-related conditions.

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