Definition

Noun: 1. A pharmaceutical drug: Leflunomide is a specific chemical compound used as a disease-modifying antirheumatic drug (DMARD). It works by inhibiting the proliferation of certain white blood cells (lymphocytes), thereby reducing the inflammation that damages joints in autoimmune diseases.
