Maltose, a promising osmotic agent in peritoneal dialysis solution

Peritoneal dialysis has undergone considerable development from a technological point of view, and osmotic agent has played the essential role in peritoneal dialysis fluid. Because the most commonly used osmotic agent is glucose and icodextrin, there are some disadvantages related to the use of glucose-based solutions and icodextrin. So it is urgent to develop a new peritoneal dialysis osmotic agent. According to these characteristics of glucose and icodextrin, it is promising to explore a better osmotic agent of peritoneal dialysis solution which is able to allow maintenance of the maximum ultrafiltration gradient, and prevent toxicity or accumulation of unwanted substances in the blood, being non-toxic or less-toxic, furthermore the metabolite should not cause significant metabolic disturbance. Maltose may be one of promising osmotic agent and may put an important influence on development of peritoneal dialysis.
