Types segmentation categorizes the market based on drug mechanisms and therapeutic classes. Corticosteroids remain the first-line treatment, accounting for the largest market share due to their anti-inflammatory efficacy and cost advantage. Immunosuppressants, including azathioprine and cyclosporine, follow as second-line therapies, driven by their role in reducing corticosteroid dependency. Biologics, such as rituximab and IL-6 inhibitors, represent a high-growth segment, fueled by demand for targeted therapies with fewer systemic side effects. Adjunctive therapies, including antihistamines and mucosal lubricants, occupy smaller but stable segments. This market taxonomy highlights evolving treatment paradigms, with biologics anticipated to gain traction as R&D investments and reimbursement policies expand.
