[Calcimimetic drugs in stage 3-5 chronic kidney disease].

This review is focused on results of application of calcimimetic drug--cinacalcet in the treatment of secondary hyperparathyroidism in patients in 3-5 stage chronic kidney disease (CKD), excluding dialysis patients (stage 5D CKD). Oral administration of cinacalcet (15-180 mg/day) significantly reduced plasma parathormone (PTH) concentrations (> or = 30% as compared to the baseline values), but simultaneously side effects occurred, among them hypocalcemia and hyperphosphatemia. Hypocalcemia was a reason for cinacalcet withdrawal in 2-15% of patients. There is a lack of studies showing the influence of advantages and disadvantages of long-term administration of cinacalcet on outcome of 3-5 stage CKD patients.
