Most cases of angina are mainly treated with oral medications to improve the uncomfortable symptoms as well as to prevent the progression of the disease. The most basic medications are mainly BAY aspirin and atorvastatin calcium. These two drugs help prevent the progression of atherosclerosis, and statins can also stabilize plaque and improve endothelial function of blood vessels. If the patient still has uncomfortable symptoms after taking these two drugs, the actual heart rate and blood pressure of the patient should also be combined with the application of beta-blockers, such as bisoprolol and metoprolol, etc. In addition, vasodilator drugs, such as isosorbide mononitrate, can be applied, which can significantly improve the symptoms of angina pectoris when taken by the elderly. However, if the patient has glaucoma, this drug should not be used.
