What is Zavesca?

Zavesca is an FDA (U.S. Food and Drug Administration) approved medication manufactured for Actelion Pharmaceuticals US, Inc., a Janssen Pharmaceutical Company. It is a glucosylceramide synthase inhibitor (the enzyme responsible for the first step in the synthesis of most glycosphingolipids) indicated as monotherapy to treat adult patients with mild to moderate type 1 Gaucher disease for whom enzyme replacement therapy (ERT) is not an option.

Type 1 Gaucher disease is caused by a lack of glucocerebrosidase, the enzyme needed for the breakdown of glycosphingolipid glucosylceramide. Lipids build up in the body and cause symptoms such as easy bruising or bleeding, weakness, anemia, bone or joint pain, enlarged liver or spleen, or weakened bones.

Zavesca is also used in patients of all ages with Niemann-Pick type-C disease, a potentially fatal disease in which glycosphingolipids build up within cells in the brain and elsewhere in the body. Zavesca is used to treat neurological symptoms which include loss of coordination, problems with eye movements that can lead to vision problems, delayed development, problems swallowing, decreased muscle tone, seizures, and learning difficulties.

What doses of Zavesca are available?

Zavesca is available in capsule form, in the following doses: 100 mg.

The recommended dosage is a 100 mg capsule, three times a day at regular intervals. The dose may be reduced to 100 mg once or twice a day in patients due to tremors or diarrhea. Dosing for patients under the age of 12 years should be adjusted according to body surface area.

Please read the patient information provided with your medication and always speak with a healthcare professional for medical advice about any changes to your dose so they can monitor and evaluate your condition.
