    Abstract:
    BACKGROUND: Hyperkalemia is common among end-stage renal disease (ESRD) patients, and consequently contributes to an increased risk of cardiac arrhythmia. Senna glycoside may decrease colonic transit time and potassium colonic reabsorption. METHODS: Patients on hemodialysis were randomized to receive either oral senna glycoside (n = 37) or control (n = 36) for 8 weeks. The primary outcomes were predialysis serum potassium and prevalence of hyperkalemia. RESULTS: At the end of the study, significantly reduced serum potassium concentrations were observed in the senna glycoside compared with the control (-0.32 [95%CI -0.43, -0.04] vs. -0.02 [95%CI -0.12, 0.05] mEq/L, p < 0.001, respectively). The prevalence of hyperkalemia during the study occurred at 13.8% in the control and 5.4% in the senna glycoside (p = 0.309). No serious adverse events were observed. CONCLUSION: Among patients with ESRD on hemodialysis, senna glycoside significantly decreases serum potassium level. Senna glycoside is a safe and possibly effective alternative treatment for hyperkalemia in ESRD.
