What this patent protects

This patent protects a packaged bicarbonate solution for use in dialysis treatment that includes dissolved ferric pyrophosphate.

USPTO Abstract

A stable packaged bicarbonate solution for use in dialysis treatment and for treating anemia, iron deficiency, or reducing the required dose of recombinant erythropoietin to treat anemia includes a bicarbonate solution into which ferric pyrophosphate is dissolved. The amount of ferric pyrophosphate dissolved in the bicarbonate solution is sufficient to provide a therapeutic effect for the treatment of anemia, iron deficiency or to reduce dose of recombinant erythropoietin needed to treat anemia when the bicarbonate solution is combined with other dialysis components to form a dialysate used for dialyzing a patient. The ferric pyrophosphate is stabilized in the bicarbonate solution by holding the solution in a polyolefin container or container liner, such as a high density polyethylene container or liner.
