The Ciclosporin segmentation by application is dominated by organ‑transplantation protocols, which account for roughly 55 % of total sales. This share reflects the drug’s role as a cornerstone immunosuppressant in kidney, liver and heart graft maintenance, where long‑term therapy drives recurring revenue. Dermatology, principally the treatment of moderate‑to‑severe psoriasis, contributes about 25 % of the market, supported by expanding indications and the shift toward oral therapy in outpatient settings. Rheumatology, covering rheumatoid arthritis and other autoimmune disorders, represents an estimated 15 % share; its growth is moderated by competition from biologics but sustained by cost‑sensitivity in emerging markets. Ophthalmology, limited to severe dry‑eye disease and ocular surface inflammation, occupies the remaining 5 % of the market. Each application segment adds a distinct revenue stream, with transplantation anchoring the market’s volume, dermatology providing the fastest CAGR, and the smaller therapeutic areas offering niche but stable contributions.
