Chronic nephritis cannot be completely eradicated. Chronic nephritis is a relatively common type of disease in clinic, and the typical clinical manifestations are hematuria, proteinuria, edema, hypertension, which can be accompanied by different degrees of renal function decline. Once diagnosed with chronic nephritis, it means that the disease will eventually develop into the uremic stage if not intervened and treated with medication. In the early stage of chronic nephritis, the application of ACEI and ARB drugs to control blood pressure and reduce urinary protein can effectively delay the deterioration of renal function, and the commonly used drugs are Irbesartan, Valsartan, Benadryl, and the goal of the treatment is to have a blood pressure of less than 130/80 ㎜ Hg, and urinary protein quantitatively less than 1 gram, and the renal function is able to be maintained stable for a long time. Once creatinine and urea increase, it means glomerular filtration rate decreases and renal function decreases, at this time, you can add urethane granules to reduce creatinine, and take Bering capsules orally to protect. Once the creatinine exceeds 707umol/L , it is uremia, which requires renal replacement therapy.
