What Cerdelga is used for
Cerdelga contains the active substance eliglustat. It belongs to a group of medicines
that decrease the production of a substance called glucosylceramide in the body.
Cerdelga is used for the long term treatment of adult patients with Gaucher disease
Gaucher disease type 1 is a rare, inherited condition in which a substance called
glucosylceramide builds up in the cells of your spleen, liver and bones.
The build-up can prevent these organs from working properly.
Cerdelga decreases the production of glucosylceramide, preventing its build-up. In
turn this helps your affected organs to work better.
Some people’s bodies break down this medicine faster than others. As a result the
amount of this medicine in the blood can differ between patients which could affect
how you will respond. Cerdelga is meant to be used in patients whose body breaks down
this medicine at normal speed (known as intermediate metaboliser and extensive metaboliser)
or slow speed (known as poor metaboliser). Your doctor will determine if Cerdelga
is suitable for you before you start taking it, using a simple laboratory test.
Gaucher disease type 1 is a lifelong condition and you must continue to take Cerdelga
as prescribed by your doctor to gain the maximum benefit from your medicine.
Ask your doctor if you have any questions about why it has been prescribed for you.
