Segmentation by type further refines the market taxonomy into two principal drug classes and their respective subtypes. The glucocorticoid class, representing 70 % of total volume, includes hydrocortisone, prednisolone, and dexamethasone, each differing in potency, half‑life, and route of administration. The mineralocorticoid class, comprising 30 % of volume, is dominated by fludrocortisone, with emerging synthetic analogues under clinical evaluation. Within glucocorticoids, hydrocortisone remains the most prescribed due to its physiological cortisol profile, while prednisolone and dexamethasone capture niche segments requiring higher anti‑inflammatory potency. This type‑based breakdown clarifies how formulation choices influence pricing tiers, reimbursement pathways, and ultimately the aggregate market size for Addison’s Disease Drugs.
