AZSTARYS vs DAYTRANA
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.
Methylphenidate is a central nervous system stimulant that blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their extracellular concentrations.
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: 10 mg transdermal patch applied to hip for 9 hours daily; may titrate weekly in increments of 5 mg to a maximum of 30 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.
Terminal half-life in children is approximately 5–6 hours; in adults, approximately 5 hours; wears off within 12 hours of patch removal.
Renal: 90% (primarily as metabolites, with 50-70% as the major metabolite (-)-phensuximide glucuronide). Fecal: <5%.
Renal (approx. 78% unchanged) and fecal (approx. 10%); remainder as metabolites.
