The present invention relates to a solution for peritoneal dialysis consisting of one or more separate solutions. A treatment free of side-effects with a simultaneous lowering of blood pressure can be achieved in that the solution contains sodium ions in a concentration in the region from 121 to 129 mmol/l, preferably at 125 mmol/l. The invention furthermore relates to a double-chambered pouch having a peritoneal dialysis solution consisting of two separate solutions which consists of a plastic pouch in which a first chamber with the first separate solution and a second chamber with the second separate solution are arranged adjacent to one another, with both chambers being separated from one another by a weld seam dimensioned such that it opens on pressure onto one of the chambers filled with liquid so that the content of the two chambers can be mixed with one another.
