ADZENYS XR-ODT vs AMPHETAMINE SULFATE
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.
Increases presynaptic release of dopamine and norepinephrine, blocks reuptake, and inhibits monoamine oxidase, resulting in CNS stimulation.
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.
5–60 mg/day orally in 1–3 divided doses, initial 5 mg once or twice daily, increase by 5 mg weekly.

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: 10-13 hours in adults with acidic urine; prolonged to 16-34 hours with alkaline urine. In children, half-life is typically shorter (6-8 hours).
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 excretion of unchanged amphetamine (approximately 30-40%) and its metabolites; urinary pH-dependent: acidic urine enhances elimination (up to 70% unchanged), alkaline urine reduces it. Minor biliary/fecal elimination (<10%).
