Leflunomide is a potent immunomodulatory agent primarily used in the treatment of rheumatoid arthritis and psoriatic arthritis. This compound functions by inhibiting the enzyme dihydroorotate dehydrogenase, which plays a crucial role in the de novo synthesis of pyrimidines, thereby reducing the proliferation of activated lymphocytes. Its unique mechanism of action not only alleviates symptoms but also slows the progression of joint damage, making it a valuable option for long-term management of autoimmune conditions.

In addition to its therapeutic applications, Leflunomide has shown promise in various research settings, including studies focused on cancer and other inflammatory diseases. Its ability to modulate immune responses opens avenues for exploring its potential in combination therapies. Researchers appreciate Leflunomide for its favorable pharmacokinetic profile and the convenience of oral administration, which enhances patient compliance. With ongoing studies, Leflunomide continues to be a compound of interest in both clinical and research environments.
