  • Peritoneal dialysis solution
    Patent number: 6156797
    Abstract: A peritoneal dialysis solution comprising at least one cation, a chloride ion contained at a concentration differing from a concentration of total cation so that the concentration of chloride ion will be lower than the concentration of total cation, and organic acids contained so as to maintain electrical neutrality depending on a difference in concentration between the total cation and chloride ion, the concentration of organic acids satisfies a predetermined equation.
