Cerdelga – Eliglustat uses, dose and side effects


84 mg hard capsules 

1. What Cerdelga is and what it is used for

Cerdelga contains the active substance eliglustat and is used for long-term treatment of adult patients with Gaucher type 1 disease .

Gaucher’s type 1 disease is a rare, inherited disease in which a substance called glucosylceramide cannot be completely broken down by the body. Therefore, glucosylceramide is stored in the spleen, liver and skeleton. The storage prevents these organs from functioning normally. Cerdelga contains the active substance eliglustat, which reduces the formation of glucosylceramide and thereby prevents its storage. This in turn helps your organs to function better.

Different people break down this drug at different speeds in the body. The amount of drug in the blood can therefore vary between patients and affect how patients respond to treatment. Cerdelga is for use in patients who break down this medicine at a normal rate (also known as intermediate or fast metabolizers) or slow speed (slow metabolizers). Your doctor will determine if Cerdelga is suitable for you before you start treatment, through a simple laboratory test.

Gaucher type 1 disease is a lifelong condition and you must continue to take this medicine as your doctor prescribes to get the maximum benefit from your medicine.

What you need to know before you take Cerdelga

Do not take Cerdelga

  • if you are allergic to eliglustat or any of the other ingredients of this medicine (listed in section 6).
  • if you are an intermediate or fast metaboliser and are using medicines known to be strong or moderate CYP2D6 inhibitors (such as quinidine and terbinafine) in combination with strong or moderate CYP3A inhibitors (such as erythromycin and itraconazole) . The combination of these drugs affects your body’s ability to break down Cerdelga and it can lead to higher levels of the active substance in your blood (see section “Other drugs and Cerdelga” for a more comprehensive list of these drugs).
  • if you are a slow metaboliser and are taking medicines called strong CYP3A inhibitors (eg itraconazole). Drugs of this type will interfere with the body’s ability to break down Cerdelga and may lead to higher levels of the active substance in the blood (see section “Other medicines and Cerdelga” for an extended list of these medicines).
  • if you are a fast metabolizer and have severe hepatic impairment.
  • if you are a fast metaboliser and have mild or moderate hepatic impairment while taking a strong or moderate CYP2D6 inhibitor.

Medicines that must not be taken in combination with each other and Cerdelga

Cerdelga must not be taken in combination with certain types of medicines. These medicines can affect your body’s ability to break down Cerdelga and this can lead to higher levels of Cerdelga in the blood. These drugs are known as strong or moderate CYP2D6 inhibitors and strong or moderate CYP3A inhibitors. There are many drugs like these and depending on how your body breaks down Cerdelga, the effects can differ from person to person. Talk to your doctor about these medicines before you start taking Cerdelga. Your doctor will decide which medicines you can use depending on how fast your body breaks down eliglustat.
