For patients with coronary artery disease who experience dyspnea, the following medications can be taken to improve the symptoms of dyspnea: first, nitrate drugs, such as nitroglycerin under the tongue or isosorbide mononitrate, can be taken to improve the symptoms of dyspnea. Secondly, certain drugs such as coenzyme Q10 can be taken to improve the performance of inadequate blood supply to the heart muscle and lack of itching. Then, drugs such as anti-platelet aggregation drugs such as aspirin, clopidogrel, and tigretol should be taken regularly, as well as statin lipid-lowering drugs such as Lipitor and Cortisol, and also regular beta-blockers such as metoprolol tartrate and metoprolol succinate, but heart rate should be closely monitored. Finally, ACEI drugs, such as captopril, can also be taken.
