Executive Summary
Dexmethylphenidate hydrochloride (d-MPH) and serdexmethylphenidate chloride (SDX) are central nervous system stimulants primarily used in attention-deficit/hyperactivity disorder (ADHD) and narcolepsy treatments. The global ADHD therapy market is projected to reach approximately USD 33.9 billion by 2027, growing at a CAGR of 6.3% (Fortune Business Insights, 2022). The segment's growth is driven by increased diagnosis rates, expanding indications, and a shift toward long-acting formulations. Both drugs present significant investment opportunities fueled by patent expiries on key competitors, regulatory approvals, and pipeline advancements. However, market entry barriers, regulatory changes, and societal concerns about stimulant abuse pose challenges.
