When a patient has a bad kidney, the drugs chosen mainly include the following categories: the first category is the drugs of Prilosec or Satan, which belong to the first category of recommended drugs. These drugs have a protective effect on the target organs of the kidney and can achieve the effect of lowering urine protein. The second category of drugs is kidney-protecting and nitrogen-lowering drugs, such as urinary toxin clear and Haikun Kidney Hi capsule, which excrete toxins such as creatinine and urea nitrogen through the intestine. Jinshui Bao contains Cordyceps sinensis to inhibit kidney fibrosis, Huangkui capsule to lower urine protein, and piperazine ferulate to improve kidney microcirculation and play a protective role for the kidneys. The third category of drugs is for the treatment of the primary disease of the kidney, such as patients with diabetes and other factors secondary to poor kidney, may be selected to lower the sugar class of drugs. For example, if the kidney is bad due to systemic lupus erythematosus, glucocorticoid hormone or glucocorticoid hormone combined with immunosuppressive therapy should be chosen. So bad kidney is not simply to say which drug is good to choose, but to choose several drugs to take at the same time according to the condition.
