Biologics for Rheumatoid Arthritis
Biologic medications have revolutionized rheumatoid arthritis (RA) treatment over the past 25 years. For patients who don't respond adequately to traditional disease-modifying antirheumatic drugs (DMARDs) like methotrexate, biologics offer targeted, highly effective therapy.
What Are Biologics?
Biologics are protein-based medications derived from living cells. Unlike traditional DMARDs that broadly suppress the immune system, biologics target specific molecules involved in the inflammatory process that drives RA.
