Icodextrin
(Redirected from Extraneal)
Icodextrin[edit | edit source]
Icodextrin is a glucose polymer used in peritoneal dialysis solutions. It is an alternative to glucose-based solutions and is particularly useful for patients undergoing long-dwell dialysis exchanges. Icodextrin is known for its ability to provide sustained ultrafiltration over extended periods, making it beneficial for patients with high peritoneal membrane transport rates.
Mechanism of Action[edit | edit source]
Icodextrin works by creating an osmotic gradient that facilitates the removal of excess fluid from the blood into the peritoneal cavity. Unlike glucose, which is rapidly absorbed, icodextrin is absorbed more slowly, allowing for prolonged ultrafiltration. This property makes it ideal for overnight or long-dwell exchanges in continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD).
Clinical Use[edit | edit source]
Icodextrin is primarily used in patients who experience inadequate ultrafiltration with standard glucose-based solutions. It is particularly beneficial for patients with high transport characteristics, where rapid absorption of glucose can lead to insufficient fluid removal. By using icodextrin, these patients can achieve better fluid balance and improved dialysis adequacy.
Side Effects[edit | edit source]
While icodextrin is generally well-tolerated, some patients may experience side effects. Common side effects include skin rash, itching, and, in rare cases, peritonitis. It is important for patients to monitor for signs of infection and report any adverse reactions to their healthcare provider.
Advantages over Glucose-Based Solutions[edit | edit source]
Icodextrin offers several advantages over traditional glucose-based peritoneal dialysis solutions:
- Prolonged Ultrafiltration: Provides sustained fluid removal over long-dwell periods.
- Reduced Glucose Load: Minimizes the metabolic impact of glucose absorption, which can be beneficial for diabetic patients.
- Improved Fluid Balance: Helps maintain better fluid balance in patients with high peritoneal transport rates.
