Assessing patiromer utilization and associated serum potassium changes in US veterans with prior sodium polystyrene sulfonate exposure.

Untreated chronic hyperkalemia is associated with an increased risk of mortality. Novel potassium binders (e.g.

Real-world evaluation of patiromer utilization and its effects on serum potassium in veterans with end stage kidney disease.

Hyperkalemia (serum potassium [K+] ≥5.1) is life-threatening in patients diagnosed with end stage kidney disease (ESKD). Patiromer is approved for the treatment of hyperkalemia, although its role in hyperkalemic patients with ESKD is not well understood.

Justification for initiating patiromer when restricted by prior authorization and clinical guidance in a US health care system.

In the Veterans Health Administration, patiromer is a formulary medication restricted by prior authorization and criteria-for-use (CFU). Historically, patiromer approval was restricted by step therapy, requiring prescribers to trial sodium polystyrene sulfonate (SPS). To describe clinical scenarios leading to patiromer initiation by characterizing patient experience with primary hyperkalemia treatment modalities, especially SPS.
