Intermittent sodium zirconium cyclosilicate Treatment May Prevent Hyperkalemia in CKD Patients: Study

Results: They studied 36 adult CKD patients. SZC treatment significantly reduced plasma potassium levels from 5.10 (inter-quartile range [IQR] 4.91–5.40) to 4.73 (IQR 4.50–5.10) mmol/l (p = 0.0003). The median incidence of any hyperkalemia reduced from 5.0 (IQR 2.0–8.0) to 1.9 (IQR 0.0–4.7) episode per patient-year (p = 0.0001), and the incidence of urgent treatment for hyperkalemia decreased from 2.0 (IQR 0.0–4.0) to 0.0 (IQR 0.0–1.5) episode per patient-year (p = 0.007).

The number of emergency room attendance and hospitalization were not significantly reduced. Intermittent SZC treatment may help prevent hyperkalemia in CKD patients. Further research is necessary to ascertain if this benefit translates into impro
