- By application, rheumatoid arthritis dominated the segment, accounting for 44.7% of the overall market share, reflecting the rising burden of chronic inflammatory disorders.
- Regarding distribution channels, hospital pharmacies held the largest share, contributing to 57.4% of total revenue, owing to their central role in administering biologics and specialty drugs.
- Regionally, North America led the global market in 2023, securing a 42.3% share, supported by strong healthcare infrastructure, ongoing research, and high adoption of immunotherapies.
Segmentation Analysis
- Drug Class Analysis: In 2023, the monoclonal antibody (mAb) segment led the immunology market with a 64.3% share. This dominance was driven by rising approvals of mAb therapies targeting cancer, autoimmune, and inflammatory conditions. These therapies offer high precision and fewer side effects, increasing their adoption. The expansion of indications for mAbs such as in rheumatoid arthritis and Crohn’s disease combined with the growing availability of biosimilars, is expected to further strengthen growth in this segment over the forecast period.
- Application Analysis: Rheumatoid arthritis accounted for 44.7% of the application segment in 2023, driven by the rising global incidence of this chronic autoimmune disease. The increasing use of advanced biologic therapies such as TNF inhibitors and interleukin blockers—is improving treatment outcomes. With growing awareness around early diagnosis and a rising aging population, demand for RA-specific immunology treatments is set to grow. Continuous research and new drug development are also expected to contribute to this segment’s sustained expansion.
- Distribution Channel Analysis: In 2023, hospital pharmacies dominated the distribution segment with a 57.4% revenue share. Their prominence stems from the administration of biologics and immunosuppressants that require professional handling and in-clinic use. These pharmacies are essential in treating complex diseases like lupus, multiple sclerosis, and rheumatoid arthritis. The increasing prevalence of chronic conditions, along with hospitals’ efforts to enhance treatment management, is expected to further strengthen the demand for hospital-based pharmacy services over the coming years.
