Abstract
The subject matter of this invention concerns an aqueous peritoneal dialysis solution which is obtained immediately prior to administration from two individual solutions, the first of which contains an osmotically active substance and the second of which contains bicarbonate ions, with the first individual solution containing anions of mono- and/or dicarboxylic acids and having a pH value of 4.5-5.8 and with the second individual solution containing an amino acid component or a peptide component and having a pH value of 7.2 to 10.0, and with the ready-to-use solution containing 23 to 26 mmoles/L bicarbonate ions and having a CO2 partial pressure of 25-70 mmHg and a pH value of 7.2 to 7.6
