In terms of Types, the market is stratified into five drug categories: Non‑steroidal anti‑inflammatory drugs (NSAIDs), COX‑2 selective inhibitors, Corticosteroids, Disease‑Modifying Antirheumatic Drugs (DMARDs), and Biologic agents. NSAIDs remain the backbone of symptom management, capturing a substantial portion of volume due to over‑the‑counter availability, yet they contribute a modest share of revenue because of lower unit prices. COX‑2 inhibitors, positioned as safer NSAID alternatives, generate higher average selling prices, thus a larger revenue contribution relative to volume. Corticosteroids, used for acute flare control, represent a niche but high‑impact segment given their potency and short‑term usage. DMARDs, including conventional synthetic agents like methotrexate, drive mid‑range pricing and are essential for disease progression mitigation. Biologics, encompassing monoclonal antibodies and fusion proteins, command premium pricing and are responsible for the fastest revenue growth, reflecting their targeted efficacy in severe cases. This typology clarifies how each drug class adds distinct value to the overall market.
