Uricidin belongs to the Chinese patent medicine, for lowering creatinine has a certain improvement effect, mainly used to assist in the treatment of renal insufficiency, often when the disease is not serious use of the effect is still okay, can assist in lowering creatinine, urea nitrogen, stabilize kidney function, but if the disease is serious, the treatment effect is not good. An important function of kidney is to excrete metabolites and harmful substances that enter the body. When the condition is not serious, that is, when the kidney can still metabolize and detoxify, urea clear can specifically excrete urea and creatinine in the intestine, thus assisting to achieve the effect of lowering creatinine. However, if the disease is serious and the kidneys have lost almost all their functions, the effect of relying on intestinal detoxification is very limited, and its effect of lowering creatinine is also minimal. Therefore, it is difficult to achieve effective creatinine lowering effect by relying on urethralin alone to eliminate toxins in the intestine, so it is clinically recommended to use urethralin in combination with other kidney-protective drugs, such as compound alpha-keto acid and sodium bicarbonate, as prescribed by the doctor, to achieve the effect of treating the disease. Patients taking urethralin need to follow medical advice and pay attention to regular reviews to monitor changes in their condition, and then adjust the drug treatment plan according to the review results to prevent deterioration of the disease. In the daily diet need to pay attention to the taste of light, avoid greasy, eat more fresh vegetables and fruits and other easily digestible food, avoid staying up late, to develop an early to bed and early to rise lifestyle.
