Serdexmethylphenidate is a derivative of dexmethylphenidate created by pharmaceutical company KemPharm. The compound is under investigation for the treatment of ADHD in children, adolescents, and adults as of 2020.[2] The drug was approved for medical use by the FDA in March, 2021. Serdexmethylphenidate is a prodrug which has a delayed onset of action and a prolonged duration of effects compared to dexmethylphenidate, its parent compound.
Formulations
Serdexmethylphenidate/dexmethylphenidate (Azstarys), a co-formulation of serdexmethylphenidate and dexmethylphenidate, was approved by the Food and Drug Administration (FDA) in March 2021, for the treatment of ADHD in those above six years of age. Co-formulation of serdexmethylphenidate with dexmethylphenidate allows for a more rapid onset of action while still retaining up to 13 hours of therapeutic efficacy.[3][4]
Due to serdexmethylphenidate’s delayed onset and prolonged duration of effects, several dosage forms containing serdexmethylphenidate have been investigated for use as long-acting psychostimulants in the treatment of ADHD. Under the developmental codename KP484, serdexmethylphenidate has been investigated as a “super-extended duration” psychostimulant, with therapeutic efficacy lasting up to 16 hours following oral administration. In 2011, MonoSol Rx entered into a partnership with KenPharm to develop oral films containing KP415.[5]
Abuse potential
The abuse potential of serdexmethylphenidate is theorized to be lower than other psychostimulants because serdexmethylphenidate is an inactive prodrug of dexmethylphenidate, and must undergo enzymatic metabolism prior to exerting any stimulant effects.[6] Common routes of administration used during the abuse of psychostimulants such as insufflation and intravenous injection have little impact on the pharmacokinetics and metabolism of serdexmethylphenidate and do not result in a faster onset of action.[7]
