Sucraid® is an enzyme replacement therapy that contains sacrosidase as a substitute for sucrase, which is one of the enzymes that is defective in individuals who have Congenital Sucrase-Isomaltase Deficiency (CSID). Sacrosidase facilitates the breakdown of sucrose (sugar) into its constituent monosaccharide units, glucose and fructose, for absorption from the small intestine. Sucraid® has been documented to help relieve the gastrointestinal symptoms associated with CSID, and as a result, help affected individuals consume a more normal diet that includes sucrose-containing foods.
