The most commonly used blood pressure lowering drugs in nephrology are selected according to the condition. In case of nephritis stage, with or without hypertension, the most commonly used drugs are ACEI class or ARB class, such as enalapril and Irbesartan tablets, which can lower the intra-glomerular pressure and urinary protein, if the patient can tolerate them. If blood pressure is still high after using ACEI class or ARB class antihypertensive drugs, calcium antagonists such as nifedipine controlled-release tablets and amlodipine benzoate tablets can be used, or diuretics such as hydrochlorothiazide tablets and furosemide tablets can be added. If it is early renal failure and the blood creatinine is greater than 280μmol/L, use ACEI class or ARB class drugs cautiously, but choose nifedipine controlled-release tablets or metoprolol, carvedilol, terazosin and other blood pressure lowering drugs. In case of uremia and hemodialysis, ARBs or ACEIs and nifedipine controlled-release tablets can be used.
