ESRD patients who undergo a major gastro-intestinal surgery can present with dysregulation of their potassium homeostasis mechanism leading to hyperkalemia. Patiromer (Veltassa) and sodium zirconium cyclosilicate (Lokelma) are two approved potassium binders used for the treatment of hyperkalemia in ESRD patients. Homeostasis. 2.
