Real-World Use of Patiromer in Patients with Hyperkalaemia: A Retrospective Study from the Valencian Community
Background and objective: Hyperkalaemia is common in patients with chronic kidney disease (CKD) treated with renin-angiotensin-aldosterone system inhibitors (RAASi) and mineralocorticoid receptor antagonists (MRAs). Although new potassium binders have demonstrated efficacy in clinical trials, eviden...

| Sumario: | Background and objective: Hyperkalaemia is common in patients with chronic kidney disease (CKD) treated with renin-angiotensin-aldosterone system inhibitors (RAASi) and mineralocorticoid receptor antagonists (MRAs). Although new potassium binders have demonstrated efficacy in clinical trials, evidence from real-world clinical practice remains limited. Materials and methods: We present a retrospective, observational, multicentre, non-interventional study aimed at evaluating the use of patiromer in patients with hyperkalaemia under routine clinical conditions in the Valencian Community. Patients who received patiromer for at least 3 months due to hyperkalaemia were included. The primary objective was to assess the evolution of serum potassium at 1, 3, 6, and 12 months after initiation of treatment. Secondary objectives included describing baseline patient characteristics, changes in RAASi and MRA therapy, and patiromer-related adverse events. Results: A total of 59 patients were included. The baseline serum potassium level was 5.72 mmol/L, showing significant reductions at 1, 3, 6, and 12 months (5.02, 5.17, 5.11, and 5.01 mmol/L, respectively; all p < 0.001). Patiromer treatment enabled continuation of RAASi in 94.9% of patients and MRAs in 98.3%. The most frequent adverse events were gastrointestinal. Patiromer was discontinued in 8 patients (13.5%), with adverse effects accounting for half of these cases. Conclusions: Our study provides real-world evidence on the effectiveness, safety, and RAASi/MRA maintenance potential of patiromer in patients with CKD and hyperkalaemia under routine care. In this setting, patiromer proved effective and well tolerated for managing hyperkalaemia and preserving RAASi/MRA therapy. |
