AZSTARYS vs DEXMETHYLPHENIDATE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AZSTARYS is a prodrug of dexmethylphenidate, a central nervous system stimulant. The exact mechanism of action in attention deficit hyperactivity disorder (ADHD) is unknown, but it is thought to block the reuptake of norepinephrine and dopamine into the presynaptic neuron, increasing their levels in the extraneuronal space.
Dexmethylphenidate is a central nervous system (CNS) stimulant. Its mechanism of action in ADHD is not fully understood, but it is believed to block the reuptake of norepinephrine and dopamine into the presynaptic neuron, increasing their levels in the extraneuronal space.
Initial: 39.2 mg oral once daily in the morning; titrate weekly by 19.6 mg increments as needed; maximum dose: 78.4 mg once daily.
Initial: 5 mg orally twice daily (morning and noon) with or without food; titrate in increments of 5 mg weekly; maximum 20 mg twice daily (40 mg/day).

Serdexmethylphenidate: 1.5 hours; dexmethylphenidate: 3.5 hours. The terminal half-life of total dexmethylphenidate after AZSTARYS is approximately 6.5 hours, supporting once-daily dosing.
2-4 hours (immediate-release); 4-5 hours (extended-release); clinical context: short half-life necessitates multiple daily dosing for immediate-release formulations
Renal: 90% (primarily as metabolites, with 50-70% as the major metabolite (-)-phensuximide glucuronide). Fecal: <5%.
Renal (78-97% as metabolites and unchanged drug, with approximately 50% as de-esterified metabolites and 30% as unchanged drug)
