Shanghai Ark Biopharmaceutical Co., Ltd. announced that Azstarys (serdexmethylphenidate, dexmethylphenidate) has been approved by China’s National Medical Products Administration (NMPA) for the treatment of patients aged 6 and above with attention‑deficit/hyperactivity disorder (ADHD). Azstarys is the world’s first compound preparation combining immediate‑release dexmethylphenidate (d‑MPH) and the prodrug serdexmethylphenidate (SDX), offering both rapid and long‑lasting effects. The drug received FDA approval in March 2021, marking the first new generation methylphenidate‑based medication in nearly two decades.

Differentiation & Clinical Advantages
Azstarys vs. Standard Methylphenidate:
| Feature | Azstarys | Conventional MPH (Ritalin, Concerta) |
|---|---|---|
| Onset | Rapid (d‑MPH component) | Variable (IR: 30‑45 min; ER: 1‑2 hr) |
| Duration | 12‑13 hours (SDX prodrug) | IR: 3‑4 hr; ER: 8‑12 hr |
| Dosing | Once daily | Often BID or multiple formulations |
| Abuse Potential | Lower (SDX prodrug reduces peak dopamine) | Higher peak exposure |
| Safety | Better sleep profiles (fewer insomnia reports) | Common insomnia, appetite suppression |
Clinical Data: US trials showed significant ADHD‑RS‑5 score reduction vs. placebo and non‑inferiority to Concerta with improved safety‑tolerability.
Competitive Landscape
