Proteinuria may be caused by kidney diseases such as nephrotic syndrome and glomerulonephritis. New drugs for lowering urinary protein are angiotensinase inhibitors (ACEI class) and angiotensin II receptor antagonists (ARB class). 1.ACEI class drugs: the common ones are captopril, enalapril and other drugs. Mainly through the inhibition of angiotensinase to dilate blood vessels, play a role in lowering blood pressure, reduce proteinuria, delay further deterioration of renal function. Besides, it can also reduce the production of pro-fibrotic factors such as TGF-β. 2. ARB drugs: common drugs are valsartan, candesartan and so on. Mainly by blocking angiotensin II vasoconstriction, elevated blood pressure, sodium retention and other effects, to play a role in lowering blood pressure, reduce proteinuria and so on. It can also prevent and control angina pectoris, coronary heart disease and so on. The above mentioned drugs can also produce a series of adverse reactions such as dry cough, dizziness, nausea and other symptoms. Therefore, it should be taken under the guidance of a professional doctor and should not be taken without authorization.
