Summary of Clinical Use
Used to treat active rheumatoid arthritis (improve physical function and slow progression), prevention of acute/chronic rejection following organ transplant (as an FDA designated orphan drug).
Mechanism Of Action and Pharmacodynamic Effects
Leflunomide acts as a pyrimidine synthesis inhibitor. It is rapidly and almost completely metabolized following oral administration to its pharmacologically active metabolite, A77 1726. Its mechanism of action has not been fully resolved but appears to be associated with a reduction in the pyrimidine level, which in turn has an inhibitory effect on autoimmune T cells [1].
