From the Guidelines
Sucralfate is not safe for renal patients on hemodialysis (HD) due to its aluminum content, which can accumulate and cause toxicity. According to the K/DOQI clinical practice guidelines for bone metabolism and disease in chronic kidney disease 1, osteomalacia due to aluminum toxicity should be prevented in dialysis patients by avoiding the use of aluminum-containing compounds, including sucralfate. The guidelines specifically recommend maintaining aluminum concentration in dialysate fluid at <10 g/L and avoiding aluminum-containing compounds to prevent osteomalacia.
Key considerations for renal patients on HD include:
- Avoiding aluminum-containing compounds, such as sucralfate, to prevent aluminum accumulation and toxicity
- Potential alternative treatments for gastrointestinal issues that do not contain aluminum
- Close monitoring of aluminum levels and bone health in patients on HD
It is essential to prioritize the safety of renal patients on HD and avoid using sucralfate due to its potential to contribute to aluminum toxicity, as recommended by the K/DOQI guidelines 1.
From the FDA Drug Label
Aluminum accumulation and toxicity (aluminum osteodystrophy, osteomalacia, encephalopathy) have been described in patients with renal impairment. Sucralfate should be used with caution in patients with chronic renal failure Patients with chronic renal failure or those receiving dialysis have impaired excretion of absorbed aluminum. In addition, aluminum does not cross dialysis membranes because it is bound to albumin and transferrin plasma proteins This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function
Sucralfate use in renal patients on HD is not recommended without caution. The drug label warns of potential aluminum accumulation and toxicity in patients with renal impairment, and the risk of toxic reactions may be greater in these patients 2, 2, 2. Key considerations include:
- Impaired excretion of absorbed aluminum in patients with chronic renal failure or those receiving dialysis
- Aluminum does not cross dialysis membranes
- Potential for aluminum accumulation and toxicity
- Increased risk of toxic reactions in patients with impaired renal function It is essential to use sucralfate with caution in patients with chronic renal failure and to carefully monitor these patients for potential adverse effects.
From the Research
Sucralfate Safety in Renal Patients on Hemodialysis
- Sucralfate may not be entirely safe for renal patients on hemodialysis due to the risk of aluminum toxicity 3, 4.
- Studies have shown that sucralfate can lead to increased serum aluminum levels in patients with chronic renal insufficiency, which can be a long-term complication of sucralfate use in this patient population 3, 4.
- The risk of aluminum toxicity may be enhanced by concurrent use of other aluminum-containing medications, such as phosphate binders or antidiarrheal preparations 3.
- However, sucralfate has been shown to be effective in reducing hyperphosphatemia in patients with chronic renal failure, although it may not result in lower serum aluminum concentrations compared to aluminum hydroxide 5.
- It is essential to monitor patients with renal failure or renal insufficiency who are undergoing prolonged sucralfate therapy for potential signs of aluminum toxicity 3.
Key Considerations
- Sucralfate should be used with caution or avoided in patients with chronic renal failure or renal insufficiency due to the risk of aluminum toxicity 3, 4.
- Patients with end-stage renal disease should avoid using sucralfate and other aluminum-containing medications concurrently 3.
- The efficacy of sucralfate in reducing serum phosphate levels is not affected by the presence of proton pump inhibitors, unlike some other phosphate binders 6.
