Biologics are genetically engineered proteins that specifically target parts of the immune system involved in inflammation, which is central to rheumatoid arthritis (RA). Unlike other RA medications that affect the entire immune system, biologics zero in on certain aspects that control the inflammation process.
Available biologics, or Biologic DMARDs (bDMARDs), work by targeting immune system pathways. These medications often inhibit various proteins, receptors, and cells that cause inflammation, such as interleukin-6, to help manage RA symptoms. Biologic drugs are considered aggressive treatments for RA and function similarly to natural proteins in your immune system.
Biologics are a subset of a class of medications known as disease-modifying antirheumatic drugs (DMARDs). While conventional DMARDs like Plaquenil (hydroxychloroquine), Arava (leflunomide), and Otrexup (methotrexate) work by stopping or reducing inflammation more broadly, biologics offer a more targeted approach.
Diagnosing rheumatoid arthritis can be complex in its early stages because initial signs and symptoms often resemble those of many other diseases. No single blood test or physical finding can confirm the diagnosis. During a physical exam, a doctor will assess joints for swelling, redness, and warmth to help determine if RA is present.
Biologics for RA aim to prevent the immune system from mistakenly attacking the healthy tissues lining the joints, a characteristic of RA. These biologic DMARDs are made from human genes and are designed to selectively target specific parts of your immune system that drive inflammation, offering a precision approach akin to a sniper’s aim.
