Why This Matters
Azstarys is in the Ritalin family. Like Vyvanse, it is a"prodrug"—meaning it’s inactive until your body converts it into the active medication. This helps the medication last longer, and also makes it harder to misuse. Unlike Vyvanse however, Azstarys also has an “immediate release” component that helps it kick in sooner.
How It Works
Azstarys contains serdexmethylphenidate, which requires conversion to the active form (dexmethylphenidate) mainly in the lower GI tract. This means the medication needs to be taken orally in order for the activation process to occur. The steady conversation process also tends to translate into a smooth, steady release profile for all-day coverage. As noted above, Azstarys also includes a small immediate-release component, so it kicks in fairly quickly (within 30 minutes). The medication lasts approximately ~ 13 hours.
Due to it’s unique activation mechanism, it also has a lower abuse potential; if someone tries to snort or inject it, it mostly bypasses the gut and doesn't get activated properly. This is why studies show people don't get a "high" from misusing it.
My Take
Both Vyvanse and Azstarys use clever chemistry to provide steady, all-day coverage with lower misuse potential. The main choice comes down to whether you do better on amphetamines (Vyvanse) or methylphenidate/Ritalin-type medications (Azstarys), how fast you need it to work, and insurance coverage.
