The global scleroderma diagnostics and therapeutics market segmentation is based on indication (localized, systemic), test type (blood tests, electrocardiogram and echocardiogram, imaging techniques, pulmonary function tests, skin biopsy), drug class (calcium channel blockers, chelating agents, corticosteroids, endothelin receptor agonists, immunosuppressive agents, PDE-5 inhibitors, prostacyclin analogues, ACE inhibitors, H2 blockers, proton pump inhibitors).
Many promising newer therapies like prostacyclin analogue, endothelin receptor antagonist, phosphodiesterase inhibitors improve clinical function and haemodynamic measures.
