Proteinuria caused by hypertension cannot be cured. Once proteinuria occurs in hypertensive patients, it indicates that it has caused kidney damage and the patient has hypertensive nephropathy. For proteinuria caused by hypertension, active treatment is needed to reduce the production of proteinuria and delay the damage to the kidneys. Blood pressure lowering drugs that reduce proteinuria and delay the progression of renal damage, such as angiotensin-converting enzyme inhibitors including benazepril and enalapril, or angiotensin II receptor antagonists including colesartan, valsartan, irbesartan and other drugs, should be given to actively control blood pressure and keep it below 130/80 mmHg. Patients with hypertension should actively control their blood pressure in general to prevent damage to the heart, brain and kidney target organs as well as the occurrence of hypertensive complications.
