ADDERALL 7.5 vs ADZENYS XR-ODT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADDERALL 7.5 is a combination of amphetamine and dextroamphetamine, which are non-catecholamine sympathomimetic amines with CNS stimulant activity. The mechanism of action involves blocking the reuptake of norepinephrine and dopamine into presynaptic neurons, as well as increasing their release into the extraneuronal space. This leads to increased levels of these neurotransmitters in the synaptic cleft, enhancing stimulation of postsynaptic receptors.
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.
5-20 mg orally 1-3 times daily; immediate-release tablets administered upon awakening and at 4-6 hour intervals as needed; extended-release capsules administered once daily upon awakening; maximum total daily dose 40 mg.
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.

The terminal elimination half-life of amphetamine is approximately 10-13 hours in adults, but can vary based on urinary pH (alkaline urine prolongs half-life up to 20 hours; acidic urine reduces it to 7-8 hours). In children, half-life is slightly shorter (6-8 hours). Clinical context: Steady-state is achieved within 2-3 days.
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: approximately 90% of a dose is excreted in urine, with about 30% as unchanged amphetamine and the remainder as metabolites (including deaminated and hydroxylated products). Fecal excretion is negligible (<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.
