The Types segment classifies ADHD Drugs into two primary pharmacologic families, each with defined subtypes that shape market composition. Stimulant agents dominate, split between methylphenidate‑based (e.g., immediate‑release, extended‑release) and amphetamine‑based (e.g., mixed salts, dextroamphetamine) formulations; together they capture roughly 70 % of revenue due to superior efficacy and broad insurance coverage. Non‑stimulant drugs, including atomoxetine, guanfacine, and clonidine, account for the remaining 30 % and are preferred for patients with comorbid conditions or stimulant intolerance. Within each family, formulation variants (IR, XR, OROS) further refine market share by addressing adherence and side‑effect profiles. This taxonomy clarifies how therapeutic class and delivery technology contribute to total market size, providing a granular view essential for competitive positioning and pipeline development in the ADHD Drugs market.
