What is eliglustat?
Eliglustat reduces the formation of a certain protein in the body in people with type 1 Gaucher disease.
Gaucher disease is a genetic condition in which the body lacks the enzyme needed to break down certain fatty materials (lipids). Lipids can build up in the body, causing symptoms such as easy bruising or bleeding, weakness, anemia, bone or joint pain, enlarged liver or spleen, or weakened bones that are easily fractured.
Eliglustat is used to treat mild to moderate type 1 Gaucher disease in adults. Eliglustat is used only if a specific liver enzyme (2D6) in your body breaks down or metabolizes drugs at a certain rate.
Eliglustat may improve the condition of the liver, spleen, bones, and blood cells in people with Type I Gaucher disease. However, eliglustat is not a cure for this condition.
Eliglustat may also be used for purposes not listed in this medication guide.
