ADDERALL 10 vs DYANAVEL XR 10
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.
Dyanavel XR is a central nervous system stimulant that increases extracellular levels of dopamine and norepinephrine by inhibiting their reuptake and enhancing their release from presynaptic neurons.
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.
Recommended starting dose for adults is 10 mg orally once daily in the morning. May increase in increments of 5-10 mg at weekly intervals based on tolerability and response. Maximum recommended dose is 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.
12 hours (amphetamine); clinical context: extended-release profile allows once-daily dosing
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.
Renal (80-90% as unchanged drug); fecal (minor, 1-5%)
