Experience of using different dosages of the drug kalimate in order to correct hyperkalemia in chronic kidney disease

Abstract

THE AIM: to evaluate the efficacy, safety, and tolerability of the preparation of calcium polystyrene sulfonate (Kalimate ® ), clinical observation was conducted in patients with chronic kidney disease who do not need dialysis, using different dosages of the drug with incomplete effectiveness of the hypokalemic diet as monotherapy for hyperkalemia. PATIENTS AND METHODS: the study included 70 patients suffering from chronic kidney disease who do not need renal replacement therapy, and with a plasma potassium level of 5.5 mmol/l or higher, after the use of hypokalemic diet therapy was ineffective. The patients were divided into 4 groups depending on the dose of calcium polystyrene sulfate. The 3 groups differed in the dose of the drug taken, the 4th group consisted of patients with reduced nutrition. Patients in all groups underwent control studies of serum potassium concentration before the start of the study, after 1 week, after 2 weeks, after 1 month, after 3, and after 6 months of treatment. RESULTS: The decrease in the level of potassium in the blood serum of group 1 patients for 6 months was 24.15 % (95 % CI 16.32-31.4 %), which in absolute value was 1.485± 0.513 mmol/l. Similar parameters for groups 2, 3 and 4 were, respectively: 22.59 % (95 %CI 15.57–31.12 %) and 1.38±0.487 mmol/L, 19.72 % (95 %CI 12.08–25.32 %) and 1.215±0.45 mmol/L, 25.24 % (95 % CI 17.86–30.24 %) and 1.58±0.502 mmol/l. CONCLUSION: the effectiveness of reducing serum potassium levels in patients with hyperkalemia on the background of chronic kidney disease who do not receive dialysis and follow only a hypokalemic diet, when using the drug polystyrene sulfate according to the instructions for 15-30 grams per day for at least 1 week with subsequent dose adjustment is an effective way of treating and correcting hyperkalemia.
