Why is this medication prescribed?

Zavesca (miglustat) is a medication prescribed for the treatment of certain rare genetic disorders. It is primarily used for the management of type 1 Gaucher disease and Niemann-Pick disease type C (NPC). Both of these conditions are lysosomal storage disorders, where there is an accumulation of certain substances within cells due to a deficiency of specific enzymes.

• Type 1 Gaucher Disease: Gaucher disease is a genetic disorder in which the body lacks an enzyme called glucocerebrosidase. This enzyme is responsible for breaking down a specific type of fat (glucocerebroside). In the absence of this enzyme, glucocerebroside accumulates in the spleen, liver, and bone marrow, leading to various symptoms.
• Niemann-Pick Disease Type C (NPC): NPC is a rare inherited disorder characterized by the abnormal accumulation of cholesterol and other fats in certain cells. It affects various organs, including the liver, spleen, and brain, and can lead to neurological symptoms.
