Class: Antihyperuricemic (antigout) agent
Generic Name: Pegloticase
Trade Name: Krystexxa®
For which conditions is this drug approved? Krystexxa is approved for use in adults to help reduce the signs and symptoms of gout that are not controlled by other treatments. Gout is a type of arthritis that occurs when uric acid builds up in blood and causes inflammation in the joints.
What is the mechanism of action? Krystexxa works by helping lower blood levels of uric acid and preventing uric acid from collecting in joints, kidneys, and other organs and causing inflammation.
How is Krystexxa typically given (administered)? Krystexxa is given by an infusion into a vein (intravenous infusion). Your doctor or a nurse will give you Krystexxa in a healthcare setting, where you can be treated if you have an allergic reaction. Treatment will take about two hours.
How are patients typically monitored? During treatment with Krystexxa, your doctor will watch you for signs of a serious allergic reaction (anaphylaxis). If a reaction occurs, it will likely be within two hours of the infusion. Your doctor will also check the uric acid levels in your blood to make sure levels aren’t increasing. In addition, you’ll be watched for flares in gout symptoms and infusion-site reactions, and patients with a history of congestive heart failure will have heart function monitored.
