PROBLEM TO BE SOLVED: To provide a peritoneal dialysis fluid containing icodextrin, in which the stability of icodextrin during heat sterilization and subsequent storage is improved, and pH is close to physiological region.SOLUTION: The peritoneal dialysis fluid consists of an acid first liquid containing icodextrin, and an alkaline second liquid containing an alkaline pH adjusting agent. After the sterilization at 110 to 130°C for 25 to 45 minutes, the pH of the first liquid is 2.3 to 2.7, and the pH of the second liquid is 8.0 to 9.0. After the sterilization, the pH after mixing the first liquid and the second liquid is 6.0 to 7.5.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT
