Within the types dimension, the market bifurcates into hydroxychloroquine and chloroquine, each further divided by salt form and dosage strength. Hydroxychloroquine sulfate dominates the autoimmune niche, offered in 200 mg and 400 mg tablets, and contributes roughly 60 % of the total type‑based revenue due to its broader safety profile and higher pricing. Chloroquine phosphate, supplied mainly as 250 mg tablets, retains a 30 % share, primarily serving malaria prophylaxis and treatment in regions where resistance is manageable. A smaller combined‑form segment (≈10 %) includes fixed‑dose combinations with primaquine or other antimalarials, targeting specific therapeutic protocols. The differentiation by salt form influences manufacturing complexity, regulatory pathways, and pricing structures, thereby shaping the market’s overall valuation. Understanding this market taxonomy is essential for forecasting demand shifts as clinical guidelines and resistance patterns evolve.
