title: Phosphate-binding effects of sucralfate in patients with chronic renal failure.
abstract: Sucralfate has been reported to reduce serum phosphate concentration in patients with chronic renal failure. To evaluate whether sucralfate could be used to treat hyperphosphatemia secondary to chronic renal failure and whether this treatment resulted in a reduced exposure to aluminum, an open-label crossover study was designed to determine the efficacy, relative potency, safety, and cost of sucralfate v aluminum hydroxide. Of the 21 hemodialysis patients completing both phases of the crossover study, serum phosphate could be maintained below 4.5 mg/dL (1.45 mmol/L) in 16 with sucralfate and in 14 with aluminum hydroxide. The 16 patients controlled on sucralfate consumed 1,694 +/- 190 mg/d of aluminum to maintain a serum phosphate concentration of 3.91 +/- 0.17 mg/dL (1.27 +/- 0.05 mmol/L) compared with the 14 patients controlled on aluminum hydroxide with an aluminum intake of 2,678 +/- 294 mg/d (P less than 0.025) and a serum phosphate concentration of 3.94 +/- 0.13 mg/dL (1.27 +/- 0.04 mmol/L). Thus sucralfate was an effective, albeit expensive, alternative to aluminum hydroxide for the treatment of hyperphosphatemia associated with chronic renal failure. Although the difference in aluminum intake was significant, use of sucralfate did not result in lower serum aluminum concentrations.
