One benefit of an ADHD prodrug is that its chemical design limits the drug’s abuse potential. In particular, serdexmethylphenidate (SDX) is a prodrug of d-methylphenidate, with lower abuse potential; the performance of SDX following IV administration confirms its decreased appeal for IV drug use. When taken orally and as intended, SDX has a gradual onset and extends the period of d-MPH exposure, which is stoked by the gradual conversion of the prodrug to active d-MPH.
The drug serdexmethylphenidate/dexmethylphenidate (SDX/d-MPH) combines 70% serdexmethylphenidate (Schedule II) and 30% immediate-release d-MPH (Schedule IV). This oral drug results in an earlier onset of action and longer duration of therapy, as well as fewer adverse events because there are no spikes in methylphenidate concentrations. Specifically, d-MPH levels peak at about 2 hours, after which the gradual conversion of SDX to d-MPH kicks in.
What has been your experience using prodrugs, such as SDX/d-MPH, for the treatment of children with ADHD?
