From the Research
Hipprex (polystyrene sulfonate) is not contraindicated in Chronic Kidney Disease (CKD), but its use requires caution due to potential gastrointestinal adverse effects and electrolyte imbalances, as noted in studies such as 1 and 2.
Key Considerations
- Hipprex works by binding to potassium in the intestinal tract and removing it from the body through the stool, making it a useful treatment for hyperkalemia in CKD patients.
- The dose may need adjustment based on the severity of kidney dysfunction and the patient's potassium levels, with common formulations including sodium polystyrene sulfonate (Kayexalate) and calcium polystyrene sulfonate, typically dosed at 15-60 grams daily, divided into multiple doses.
- Patients should be monitored for electrolyte imbalances, particularly sodium levels when using the sodium form, as CKD patients often have issues with sodium retention.
- Modern alternatives like patiromer or sodium zirconium cyclosilicate may be considered for some CKD patients due to potentially better safety profiles, as discussed in 3 and 4.
Safety and Efficacy
- Studies such as 2 have shown that patiromer and sodium zirconium cyclosilicate are safe and effective in treating hyperkalemia, with patiromer having lower rates of hyperkalemia compared to standard of care.
- However, sodium zirconium cyclosilicate may be associated with an increase in edema, which could have important adverse consequences in patients with chronic kidney disease and or heart failure, as noted in 2.
Monitoring and Treatment
- Regular monitoring of electrolytes is essential during treatment with Hipprex or alternative medications.
- Patients should be closely monitored for signs of gastrointestinal adverse effects, including rare but serious intestinal necrosis.
- Treatment should be individualized based on the patient's specific needs and medical history, with consideration of alternative medications if necessary.
