ADDERALL 5 vs ADZENYS XR-ODT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall 5 is a combination of dextroamphetamine and amphetamine, which are central nervous system stimulants. They increase the levels of dopamine and norepinephrine in the synaptic cleft by inhibiting their reuptake and promoting their release from presynaptic neurons.
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.
Initial: 5 mg orally once or twice daily; increase by 5 mg increments at weekly intervals. Maximum: 40 mg/day in divided doses.
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.

Immediate-release: 9–11 hours (mean 10 hours for dextroamphetamine); extended-release: 10–13 hours. Terminal half-life may be prolonged with urinary pH >7.
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.
Renal (90% as unchanged drug and metabolites; ~30% unchanged), minor fecal elimination (<5%).
Renal: approximately 90% as unchanged drug and metabolites (30%-40% as amphetamine, 40%-50% as hippuric acid and benzoic acid). Fecal: <4%. Biliary: negligible.
