Segmentation by types distinguishes the originator biologic Remicade from its biosimilar counterparts, a classification that underpins pricing dynamics and volume distribution. The originator segment, comprising the patented infliximab formulation, retains premium pricing and accounts for approximately 55 % of the market, sustained by brand loyalty, extensive clinical data, and exclusive contracts in certain regions. Biosimilars—such as Inflectra, Remsima, and others—form the remaining 45 % and are gaining traction through cost‑containment initiatives, hospital tender programs, and parallel‑track approvals. Within the biosimilar category, sub‑segments can be identified by manufacturer and market penetration level, which affect adoption rates across healthcare systems. This type‑based taxonomy clarifies how price elasticity, patent expiry, and regulatory pathways redistribute market share, enabling stakeholders to model revenue erosion for the originator and growth potential for biosimilar entrants.
