If a patient has shortness of breath at night, the cause of shortness of breath should be examined quickly, such as coronary artery disease, unstable angina, myocarditis or pericarditis, etc. In this case, nitrate drugs such as sublingual nitroglycerin or oral isosorbide mononitrate tablets can be taken. You can also take anti-platelet aggregation drugs, such as aspirin, clopidogrel, Tegretol, etc. You can also take statin lipid-lowering drugs, such as Lipitor. If the shortness of breath at night is due to thyroid dysfunction, such as hyperthyroidism, you can take Sage or Meclizine Hydrochloride to relieve the condition. For patients with unexplained shortness of breath, mild cases can be relieved by taking certain Chinese medicines, such as Compound Danshin Drops and Astragalus Yixi Drops.
