The types segmentation classifies allergic conjunctivitis treatments into five principal therapeutic classes: Antihistamines, Mast‑cell stabilizers, Non‑steroidal anti‑inflammatory drugs (NSAIDs), Corticosteroids, and Immunomodulators. Antihistamines—both first‑generation (e.g., diphenhydramine) and second‑generation agents (e.g., olopatadine)—provide rapid symptom relief and dominate the market, capturing an estimated 45 % of sales due to extensive over‑the‑counter availability. Mast‑cell stabilizers (e.g., cromolyn sodium) act prophylactically, contributing about 15 %, especially in pediatric cohorts. NSAIDs (e.g., ketorolac) address inflammatory components, holding roughly 10 % of the market. Corticosteroids (e.g., loteprednol) are reserved for acute exacerbations, accounting for 12 %, while Immunomodulators such as cyclosporine and emerging biologics occupy the remaining 18 %, reflecting higher pricing and niche adoption. This taxonomy clarifies how each drug class supports distinct clinical pathways and collectively shapes the overall market dynamics of allergic conjunctivitis treatments.
