Insights
Sevelamer hydrochloride effectively lowers phosphorus in children with end-stage renal disease, potentially preventing vascular calcification. Compounding pharmacists are crucial for preparing this medication until FDA approval and liquid forms are available.
Area of Science:
- Nephrology
- Pediatric Nephrology
- Clinical Pharmacy
Background:
- Hyperphosphatemia is a significant clinical issue in pediatric end-stage renal disease (ESRD).
- Calcium-based phosphate binders, a common treatment, carry risks of vascular calcification.
- Alternative phosphate binders are needed to mitigate these complications.
Purpose of the Study:
- To evaluate the efficacy of sevelamer hydrochloride in managing hyperphosphatemia in children with ESRD.
- To explore the potential of sevelamer hydrochloride in preventing vascular and soft-tissue calcifications.
- To highlight the role of compounding pharmacists in providing sevelamer hydrochloride to pediatric patients.
Main Methods:
- Review of existing evidence on sevelamer hydrochloride use in pediatric dialysis patients.
- Analysis of serum phosphorus and calcium-phosphorus ion product levels.
- Assessment of potential long-term benefits regarding calcification.
Main Results:
- Sevelamer hydrochloride demonstrates effectiveness in reducing serum phosphorus levels.
- It also lowers the calcium-phosphorus ion product, a key factor in calcification.
- The drug shows promise in preventing soft-tissue and vascular calcifications.
Conclusions:
- Sevelamer hydrochloride is an effective option for controlling hyperphosphatemia in pediatric ESRD patients on dialysis.
- It may play a vital role in preventing calcification complications associated with ESRD.
- Compounding pharmacists are essential for access until formal approval and liquid formulations are available.
Abstract:
Control of hyperphosphatemia is a major clinical challenge in children with end-stage renal disease. The best treatment option is a calcium-based phosphate binder, but there is evidence that this treatment protocol causes long-term complications, including vascular calcification. Sevelamer hydrochloride has been shown to be effective in reducing serum phosphorus levels and the calcium-phosphorus ion product in children on maintenance dialysis and may be key in preventing soft-tissue and vascular calcifications in such patients. Until the U.S. Food and Drug Administration approves the use of sevelamer hydrochloride in children undergoing dialysis and a liquid dosage form becomes available, compounding pharmacists will need to prepare this unique compound for these patients.
