Chronic renal insufficiency is treated with more drugs, mainly symptomatic treatment, such as renin-angiotensin-aldosterone receptor antagonist (such as valsartan, Benadryl), diuretics (furosemide, torasemide), recombinant human erythropoietin, sodium bicarbonate and so on. 1. Renin-angiotensin-aldosterone receptor antagonist: patients with chronic renal function are mostly hypertensive, so they can follow the doctor’s advice to choose captopril, valsartan, benadryl and so on. These drugs can effectively control blood pressure, but also can correct the glomerular hyperperfusion state, delay the further development of the disease. 2. Diuretics: Patients with chronic renal insufficiency will have different degrees of edema due to the decline in renal excretory function, which can affect cardiorespiratory function, etc. Patients can follow the doctor’s instructions to choose diuretics. Patients can follow the doctor’s instructions to choose diuretics for treatment, such as furosemide, torasemide hydrochlorothiazide, etc., which can play the role of diuretic potassium excretion. 3. Recombinant human erythropoietin: recombinant human erythropoietin is suitable for patients with chronic renal insufficiency, combined with hemoglobin less than 100g/L, can correct anemia, relieve the weakness caused by anemia and other uncomfortable symptoms. 4. Sodium bicarbonate: chronic renal insufficiency patients, due to the decline in renal function, resulting in a decline in the body’s acid-excreting function, often combined with acidosis, at this time, sodium bicarbonate can be chosen to correct acidosis, relieve discomfort symptoms. Patients with chronic renal insufficiency are advised to consult a regular hospital in time and follow the doctor’s instructions for standardized treatment. Take the above drugs need to follow the doctor’s advice, not unauthorized use of drugs, so as not to aggravate the condition.
