On March 2, the US FDA has approved a new drug application (NDA) for AZSTARYS (code name: KP415), once a day, for the treatment of attention deficit hyperactivity disorder (ADHD) in patients 6 years and older. Will be commercialized in the United States. To
AZSTARYS is a compound capsule dosage form composed of dexmethylphenidate (d-MPH) prodrug serdexmethylphenidate (SDX) and immediate release d-MPH. AZSTARYS contains 30% immediate release d-MPH and 70% extended release new SDX. After being absorbed through the gastrointestinal tract, SDX is converted to d-MPH, and d-MPH is gradually released within a day.
Compared with the currently marketed drugs Vyvanse (Ridexamphetamine Dimesylate Capsules) and Osmotic (Methylphenidate Hydrochloride Sustained Release Tablets), AZSTARYS has the advantage of immediate onset due to the immediate release of d-MPH. Compared with Adderall XR (amphetamine complex salt sustained-release capsules) and Focalin XR (dexmethylphenidate hydrochloride sustained-release capsules), because SDX is a prodrug, it can reduce drug dependence.
