Within the Targeted Drugs for Multiple Sclerosis segmentation, the type dimension separates products into small‑molecule oral agents, biologic injectables (primarily monoclonal antibodies), and emerging peptide‑based or nucleic‑acid therapies. Small‑molecule agents, exemplified by fingolimod and dimethyl fumarate, dominate the market share because of established oral administration pathways and lower manufacturing complexity, contributing roughly 45 % of total revenues. Biologic injectables, including natalizumab, ocrelizumab and alemtuzumab, command a higher price per treatment course and together represent about 40 % of market value; their mechanism‑of‑action—selective immune‑cell modulation—supports premium pricing despite a smaller patient pool. Emerging peptide‑based and antisense oligonucleotide candidates, still in late‑stage development, account for the remaining 15 % and are projected to expand as regulatory approvals progress. This typology clarifies how each sub‑type drives distinct cost structures, R&D intensity, and adoption curves within the overall market.
