This type of drug can not only lower the patient’s blood pressure, but also increase the blood flow to the kidneys, reduce proteinuria, prevent left ventricular remodeling, and delay the progression of heart failure and angina pectoris patients. Therefore, this type of drug is widely used in the clinic, and it has relatively few adverse effects, and is also ideal for men who do not want to have children, because it does not affect male sexual function. Some patients may experience angioneurotic edema and dizziness during the application of this type of drug, but they are relatively rare. It is more advantageous in combination with hydrochlorothiazide tablets, which can better lower the blood pressure of patients. It is important to note that it should not be taken by pregnant women and those with severe renal dysfunction.
