ADDERALL 10 vs ADZENYS ER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall 10 contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote the release of dopamine and norepinephrine from presynaptic neurons, inhibit their reuptake, and inhibit monoamine oxidase activity, thereby increasing extracellular levels of these neurotransmitters in the central nervous system.
ADZENYS ER is a central nervous system (CNS) stimulant that blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their concentrations in the synaptic cleft.
10 mg orally once daily in the morning, with or without food; may increase by 5-10 mg weekly based on tolerability and response; usual effective dose 10-40 mg/day divided into 2-3 doses; maximum 60 mg/day.
Adults: Initial 5-10 mg orally once daily; titrate in 5-10 mg increments weekly to optimal response; max 60 mg/day.

Terminal elimination half-life: dextroamphetamine 9-11 hours, levoamphetamine 11-14 hours (Adderall is a mixed salt). In adults, mean half-life ~10 hours; in children, slightly shorter (6-8 hours). Clinical context: steady-state reached in 2-3 days; dosing interval typically 4-6 hours for immediate-release.
6-8 hours in adults; in children 3-6 hours, requiring twice-daily dosing for sustained effect
Renal: 70-80% (30-40% as unchanged amphetamine; remainder as deaminated and hydroxylated metabolites). Fecal: minimal (<5%). Biliary: negligible. Urinary pH affects excretion: acidic urine increases elimination, alkaline urine decreases.
70% renal (30% unchanged, 40% as metabolites), 30% fecal/biliary
