ADZENYS XR-ODT vs DYANAVEL XR 20
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adzenys XR-ODT contains amphetamine, a central nervous system stimulant that increases extracellular levels of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals.
DYANAVEL XR is a central nervous system (CNS) stimulant. The mode of action is primarily through blockade of the reuptake of norepinephrine and dopamine into the presynaptic neuron, increasing their levels in the extraneuronal space. It also releases these monoamines from storage sites. The dextroamphetamine component is more potent than amphetamine in inhibiting norepinephrine reuptake, while the amphetamine component is more potent in inhibiting dopamine reuptake.
Initial: 9.4 mg orally once daily in the morning; titrate in increments of 9.4 mg per week based on tolerability and response. Maximum: 56.4 mg once daily.
Initial 20 mg orally once daily in the morning, with or without food; may increase by 10 mg weekly to maximum 60 mg/day.

Approximately 9-14 hours in adults, 8-11 hours in children (6-12 years). Extended-release pharmacokinetics produce a longer clinical duration compared to immediate-release formulations.
Terminal elimination half-life: 6-8 hours (stable metabolite). Clinical context: Twice-daily dosing typical due to pharmacokinetic profile; extended half-life compared to immediate-release amphetamine.
Renal: approximately 90% as unchanged drug and metabolites (30%-40% as amphetamine, 40%-50% as hippuric acid and benzoic acid). Fecal: <4%. Biliary: negligible.
Renal: 90% (unchanged drug and metabolites, primarily hippuric acid). Fecal/biliary: <1%.
