What is eliglustat?
Eliglustat is a prescription medicine that is used to treat Gaucher’s disease.
CERDELGA (eliglustat) capsules contain eliglustat tartrate, which is a small molecule inhibitor of glucosylceramide synthase that resembles the ceramide substrate for the enzyme, with the chemical name N-((1R,2R)-1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-1-hydroxy-3-(pyrrolidin-1-yl)propan-2-yl)octanamide (2R,3R)-2,3-dihydroxysuccinate. Its molecular weight is 479.59, and the empirical formula is C23H36N2O4+½(C4H6O6) with the following chemical structure:
Each capsule of CERDELGA for oral use contains 84 mg of eliglustat (equivalent to 100 mg of eliglustat tartrate). The inactive ingredients are candurin silver fine, FD&C blue 2, gelatin, glyceryl behenate, hypromellose, lactose monohydrate, microcrystalline cellulose, and yellow iron oxide.
Mechanism of Action
Gaucher disease is caused by a deficiency of the lysosomal enzyme acid β-glucosidase. Acid β-glucosidase catalyzes the conversion of the sphingolipid glucocerebroside into glucose and ceramide. The enzymatic deficiency causes an accumulation of glucosylceramide (GL-1) primarily in the lysosomal compartment of macrophages, giving rise to foam cells or “Gaucher cells.”
The clinical features of this lysosomal storage disorder (LSD) are reflective of the accumulation of Gaucher cells in the reticuloendothelial system (liver, spleen, bone marrow, and other organs). The accumulation of Gaucher cells in the liver, spleen, and bone marrow leads to organomegaly and skeletal disease. Presence of Gaucher cells in the bone marrow and spleen leads to clinically significant anemia and thrombocytopenia.
CERDELGA is a specific inhibitor of glucosylceramide synthase (IC50=10 ng/mL) and acts as a substrate reduction therapy for GD1 by reducing the production of GL-1. By reducing GL-1 production, CERDELGA alleviates the accumulation of GL-1 in the target organs.
