4Beta blocker
Beta blockers are widely used in medicine to treat many diseases, including coronary artery illness and angina. In patients with angina, they are often regarded as first-line therapy. They block the effects of adrenaline on your heart, which can slow your heart rate and reduce the force of contraction in heart muscles. These result in a reduction in the amount of oxygen necessary by your heart muscles and alleviate symptoms of angina. After taking this drug, patients often experience a significant diminishing of angina episodes. Due to these benefits, it is typically the first option in treating this condition. Some common side effects of beta blockers are depression, erectile dysfunction, lung disease, asthma, and fatigue. [4]
