"The US Food and Drug Administration (FDA) has approved soluble ferric pyrophosphate (Triferic, Rockwell Medical) to replace iron and maintain hemoglobin in adults with chronic kidney disease who are undergoing dialysis.
The procedure is accomplished by instilling peritoneal dialysis fluid through a conduit into the peritoneal cavity. With the exception of lactate, present as a bicarbonate precursor, electrolyte concentrations in the fluid have been formulated to attempt to normalize plasma electrolyte concentrations resulting from osmosis and diffusion across the peritoneal membrane (between the plasma of the patient and the dialysis fluid). Toxic substances and metabolites, present in high concentrations in the blood, cross the peritoneal membrane into the dialyzing fluid. Dextrose in the dialyzing fluid is used to produce a solution hyperosmolar to the plasma, creating an osmotic gradient which facilitates fluid removal from the patients plasma into the peritoneal cavity. After a period of time (dwell time), the fluid is drained by gravity from the cavity.
