Uric acid is a chemical that forms when the body breaks down substances known as purines. When cancer cells are destroyed by chemotherapy, they may release purines and other substances into the body. When the body breaks down these purines, uric acid levels can increase and cause problems.
Elitek is an enzyme called urate oxidase (an enzyme is a protein that starts a chemical reaction). Urate oxidase causes a reaction that converts uric acid into an inactive form that is easier for the body to excrete. This can help lower uric acid levels, or prevent uric acid levels from increasing in the first place.
Urate oxidase is not naturally found in humans. Instead, Elitek is made from a genetically altered strain of yeast.
Is It Safe for Children to Use Elitek?
This product is approved for use in children, regardless of age. In clinical studies, children younger than age 2 were less likely to have normal uric acid levels within 48 hours of starting treatment than children 2 to 17 years of age. There were not enough children younger than 6 months old in clinical trials to determine if they would respond differently to the medicine than older children.
Can Older Adults Use It?
Older adults can be treated with Elitek. In clinical studies, older adults tolerated and responded to the medication no differently than younger age groups.
