Oral sorbents for small, charged uremic toxins, and carbon block for regeneration of dialysate: Fourth down and long

Complexities of sorbent regeneration of dialysate led me to look at other ways to use sorbents to remove uremic toxins. An oral sorbent containing cation and anion exchangers showed effective binding of potassium, phosphate, sodium, hydrogen, and ammonium (from urea) in vitro. Animal studies are ongoing. Carbon block columns can effectively bind organic and middle molecules toxins from the dialysate. Together, these two technologies have the potential to greatly simplify dialysis for end-stage renal disease patients.
