Azstarys is a once-daily prescription stimulant medication approved by the FDA for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients aged 6 and older. It is manufactured by Corium, a Sun Pharmaceutical company.
Azstarys combines two active ingredients: serdexmethylphenidate (SDX), a prodrug that slowly converts into dexmethylphenidate in the body, and immediate-release dexmethylphenidate (d-MPH). This unique prodrug design provides both rapid onset and extended duration of ADHD symptom control throughout the day.
Azstarys works by increasing levels of norepinephrine and dopamine in the brain — two neurotransmitters essential for focus, attention, and impulse control. It does this by blocking the reuptake of these chemicals into nerve cells, making more of them available in the brain.
What makes Azstarys unique is its prodrug component (serdexmethylphenidate). The prodrug must be metabolized in the body before it becomes active dexmethylphenidate, which means the medication is released gradually over the course of the day. Combined with the immediate-release component, patients get fast-acting relief that lasts.
All doses are taken once daily in the morning. Capsules can be swallowed whole or opened and sprinkled on applesauce for patients who have difficulty swallowing.
Azstarys scores a 55 out of 100 on our findability scale, meaning it can be intermittently difficult to find at your local pharmacy. While Azstarys is not listed in the FDA's official drug shortage database, it is a brand-only Schedule II stimulant — and the broader ADHD medication demand surge that began in late 2022 continues to cause ripple effects across all stimulant medications.
