Description

technical field [0001] The invention relates to a pharmaceutical preparation and a preparation method, in particular to a compound alpha-ketoacid chewable tablet and a preparation method for treating chronic renal failure. Background technique [0002] Since the development of hemodialysis and CAPD treatment in the 1960s and 1970s, nephrologists began to lose interest in the conservative treatment of renal failure. However, in the early 1980s, nutritional therapy for chronic renal failure aroused widespread attention again. In 1981, Franz VOLHARD observed that limiting daily protein intake could significantly improve the symptoms of uremia. It has been established that the severity of uremia symptoms is related to the accumulation of protein metabolic degradation products. Therefore, for many years, a low-protein diet has been used as a measure to relieve the symptoms of uremia. Moreover, a low-protein diet can reduce acid load and phosphorus intake, thereby preventing aci...
