Summary of Clinical Use Click here for help
Serdexmethylphenidate in combination with dexmethylphenidate was approved by the FDA in March 2021 as a treatment for ADHD in children ≥6 years old. The orally administered fixed dose combination was known as KP415 during the development process. Serdexmethylphenidate has a delayed onset and prolonged duration of effects, so acts as a long-acting psychostimulant, whilst dexmethylphenidate provides a more rapid onset of action.
