Peritoneal dialysis fluid
View Patent ↗The present invention concerns a peritoneal dialysis fluid with enhanced ultrafiltration during the dialysis dwell period. According to the present invention this is achieved by a peritoneal dialysis fluid comprising sodium ions, osmotic agent and a buffer, characterised in that it comprises citrate at a level of 4 to 10 mM in a final solution ready for use.
1. A peritoneal dialysis fluid comprising sodium ions, an osmotic agent, and a buffer, the peritoneal dialysis fluid further including citrate at a concentration of 4 to 10 mM in a final solution, said final solution being ready for use.
2. The peritoneal dialysis fluid according to claim 1 , wherein the citrate is present at a concentration of 5-9 mM in the final solution.
3. The peritoneal dialysis fluid according to claim 1 , wherein the citrate is present at a concentration of 7-8 mM in the final solution.
4. The peritoneal dialysis fluid according to claim 1 , wherein the peritoneal dialysis fluid includes 1-10% by weight of the osmotic agent, 90-140 mM sodium ions, and 0.0-1.75 mM calcium ions in the final solution.
5. The peritoneal dialysis fluid according to claim 1 , wherein the osmotic agent is selected from the group consisting of glucose, polymers of glucose, amino sugars, essential and non-essential amino acids, and N-acetyl glucose amine (NAG).
6. The peritoneal dialysis fluid according to claim 1 , wherein the peritoneal dialysis fluid includes, as a buffer, bicarbonate, lactate, or bicarbonate and lactate in a total concentration of 5-28 mM in the final solution.
7. The peritoneal dialysis fluid according to claim 1 , including 1.5-4% by weight of glucose as the osmotic agent in the final solution.
8. The peritoneal dialysis fluid according to claim 1 , including 5-10% by weight of glucose polymer as the osmotic agent in the final solution.
9. The peritoneal dialysis fluid according to claim 1 , including 1.5-4% by weight of N-acetyl glucose amine (NAG) as the osmotic agent in the final solution.
