Introduction
Leflunomide is an immunomodulatory agent primarily used in the management of rheumatoid arthritis and psoriatic arthritis. As an immunosuppressant, leflunomide inhibits pyrimidine synthesis, leading to reduced lymphocyte proliferation. Its therapeutic efficacy and safety profile have made it a mainstay in autoimmune disease treatment. Securing reliable suppliers for leflunomide—whether for generic production, research, or clinical use—is critical for pharmaceutical companies, healthcare providers, and distributors. This article examines the leading suppliers of leflunomide, highlighting manufacturing capabilities, regulatory compliance, and market dynamics.
