Information

name:Leflunomide
ATC code:L04AK01
route:oral
n-compartments2

Leflunomide is an immunomodulatory agent classified as a disease-modifying antirheumatic drug (DMARD). It works primarily by inhibiting dihydroorotate dehydrogenase, thus blocking pyrimidine synthesis, and is used in the treatment of rheumatoid arthritis and psoriatic arthritis. It is approved and widely used today for these indications.
