There is no latest therapeutic drug for chronic nephritis, and its current applications mainly include drugs to control hypertension, drugs to reduce urinary protein, anticoagulant and antiplatelet drugs, lipid-regulating drugs, glucocorticoids and cytotoxic drugs. 1. Drugs to control hypertension: including felodipine, metoprolol, ACEI/ARB drugs such as chlosartan, enalapril and so on. 2. Drugs to reduce urinary protein: ACEI and ARB drugs can reduce urinary protein in patients with chronic nephritis. 3. Anticoagulant and antiplatelet drugs: including aspirin, clopidogrel and other antiplatelet drugs, warfarin and other anticoagulant drugs. 4. Lipid-regulating drugs: commonly used statins such as atorvastatin, resuvastatin, fenofibrate and so on. 5. Glucocorticoid and cytotoxic drugs: if the pathological type of chronic nephritis is clear, glucocorticoid such as prednisone, methylprednisolone and so on, cytotoxic drugs such as cyclophosphamide, cyclosporine and so on can be chosen. Chronic nephritis patients should go to the hospital in time, under the guidance of professional physicians to develop a drug program, do not self-medication.
