Overview
This is a summary of the European public assessment report (EPAR) for Leflunomide ratiopharm. It explains how the Committee for Medicinal Products for Human Use (CHMP) assessed the medicine to reach its opinion in favour of granting a marketing authorisation and its recommendations on the conditions of use for Leflunomide ratiopharm.
Leflunomide ratiopharm is a medicine that contains the active substance leflunomide. It is available as white round tablets (10 and 20 mg).
Leflunomide ratiopharm is a ‘generic medicine’. This means that Leflunomide ratiopharm is similar to a ‘reference medicine’ already authorised in the European Union (EU) called Arava.
Leflunomide ratiopharm is used to treat adults with active rheumatoid arthritis (an immune system disease causing inflammation of the joints) or active psoriatic arthritis (a disease causing red, scaly patches on the skin and inflammation of the joints).
The medicine can only be obtained with a prescription.
Leflunomide ratiopharm treatment should be started and supervised by a specialist who has experience in the treatment of rheumatoid arthritis and psoriatic arthritis. The doctor should carry out blood tests to check the patient’s liver, white blood cell counts and platelet counts before prescribing Leflunomide ratiopharm, and regularly during treatment.
Leflunomide ratiopharm treatment starts with a ‘loading dose’ of 100 mg once a day for three days, followed by a maintenance dose. The recommended maintenance dose is 10 to 20 mg once a day in patients with rheumatoid arthritis, and 20 mg once a day in patients with psoriatic arthritis. The medicine usually starts to have an effect after four to six weeks. Its effect may improve further for up to six months.
The active substance in Leflunomide ratiopharm, leflunomide, is an immunosuppressant. It reduces inflammation by reducing the production of immune cells called ‘lymphocytes’, which are responsible for inflammation. Leflunomide does this by blocking an enzyme called ‘dihydroorotate dehydrogenase’, which is necessary for the lymphocytes to multiply. With fewer lymphocytes, there is less inflammation, helping to control the symptoms of arthritis.
The applicant presented data on experimental models from the scientific literature.
Because Leflunomide ratiopharm is a generic medicine, studies in patients have been limited to tests to determine that it is bioequivalent to the reference medicine, Arava. Two medicines are bioequivalent when they produce the same levels of the active substance in the body.
Because Leflunomide ratiopharm is a generic medicine and is bioequivalent to the reference medicine, its benefit and risk are taken as being the same as the reference medicine’s.
The CHMP concluded that, in accordance with EU requirements, Leflunomide ratiopharm has been shown to have comparable quality and to be bioequivalent to Arava. Therefore, the CHMP’s view was that, as for Arava, the benefit outweighs the identified risk. The Committee recommended that Leflunomide ratiopharm be given marketing authorisation.
The European Commission granted a marketing authorisation valid throughout the European Union for Leflunomide ratiopharm on 29 November 2010.

Pharmacotherapeutic group
ImmunosuppressantsTherapeutic indication
Leflunomide is indicated for the treatment of adult patients with:
- active rheumatoid arthritis as a 'disease-modifying antirheumatic drug' (DMARD);
- active psoriatic arthritis.
Recent or concurrent treatment with hepatotoxic or haematotoxic DMARDs (e.g. methotrexate) may result in an increased risk of serious adverse reactions; therefore, the initiation of leflunomide treatment has to be carefully considered regarding these benefit / risk aspects.
Moreover, switching from leflunomide to another DMARD without following the washout procedure may also increase the risk of serious adverse reactions even for a long time after the switching.
