What is Lefno 20mg (LEFLUNOMIDE)?
DMARD for rheumatoid arthritis and psoriatic arthritis. Second-line after methotrexate failure or intolerance. Once-daily dosing due to long half-life of active metabolite.
How it Works
Prodrug converted to teriflunomide — inhibits DHODH, blocking de novo pyrimidine synthesis in proliferating T and B cells — reduces immune-mediated joint inflammation.
