Scientific Background: Leflunomide is an Immuno-suppressant, it inhibits de novo synthesis of pyrimidine nucleotides and the activity of the protein kinase. It is a part of the known “disease-modifying anti-rheumatic drugs” (DMARD). It has been suggested that leflunomide modulates the expansion of activated autoimmune lymphocytes acting on the regression of rheumatoid conditions (1-2). It has been shown to have a double mechanism of action by slowing down and relieving the pain of rheumatoid arthritis. Studies have shown the lethal effects of Leflunomide after administration to mice in various doses (3).
