ADDERALL 10 vs DAYTRANA
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.
Methylphenidate is a central nervous system stimulant that blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their extracellular concentrations.
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.
Initial: 10 mg transdermal patch applied to hip for 9 hours daily; may titrate weekly in increments of 5 mg to a maximum of 30 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.
Terminal half-life in children is approximately 5–6 hours; in adults, approximately 5 hours; wears off within 12 hours of patch removal.
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 (approx. 78% unchanged) and fecal (approx. 10%); remainder as metabolites.
