Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall XR is a central nervous system (CNS) stimulant. It contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote release of catecholamines (primarily dopamine and norepinephrine) from presynaptic nerve terminals and inhibit their reuptake, leading to increased synaptic concentrations. The exact mechanism of action in attention deficit hyperactivity disorder (ADHD) is not fully understood but is thought to involve activation of dopaminergic and noradrenergic pathways in the prefrontal cortex.
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.
20-60 mg orally once daily in the morning; start at 20 mg once daily, titrate by 10 mg weekly based on tolerability and response.
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.

The terminal elimination half-life is 10–13 hours for dextroamphetamine (the more active enantiomer) in adults; for the racemic mixture (dextroamphetamine/amphetamine), the half-life is shorter (6–8 hours) due to differential metabolism. Clinical context: Steady-state achieved within 2–3 days; once-daily dosing is sufficient.
12 hours (amphetamine); clinical context: extended-release profile allows once-daily dosing
Renal: approximately 90% (30–40% unchanged, remainder as metabolites including dehydroamphetamine and hydroxylated metabolites). Fecal: <4%. Biliary: minimal.
