Elevated creatinine caused by high blood pressure is generally considered hypertensive kidney damage, which can be treated by controlling high blood pressure and taking creatinine-lowering drugs, but it is generally difficult to recover effectively. 1. Control high blood pressure: if creatinine is elevated and <265μmol/L, you can take perindopril, timosartan and other antihypertensive drugs to adjust the blood pressure to normal; if creatinine is elevated and ≥265μmol/L, it is recommended to apply nifedipine extended-release tablets and other drugs to control the blood pressure; normal blood pressure can help to slow down the progression of kidney disease. 2. Taking creatinine-lowering drugs: If the creatinine is high due to hypertension, patients need to take creatinine-lowering drugs such as nephronin and urethane granules in addition to controlling blood pressure. It is recommended that hypertensive nephropathy patients go to the hospital in time and choose the appropriate treatment plan under the guidance of doctors to control blood pressure and slow down the rate of kidney progression.
