ADDERALL 30 vs DYANAVEL XR 15
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
Dyanavel XR contains amphetamine, which is a central nervous system stimulant that increases synaptic concentrations of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals.
Initial: 5 mg orally once or twice daily; increase by 5 mg increments weekly; usual maintenance: 20-30 mg daily in divided doses; maximum: 40 mg/day
1-3 capsules orally once daily in the morning. Each capsule contains 15 mg of amphetamine (equivalent to 15 mg dextroamphetamine/amphetamine).

Terminal elimination half-life: d-amphetamine 10-13 hours, l-amphetamine 13-15 hours; in adults (children: 6-8 hours). The longer half-life allows for once-daily dosing.
Terminal elimination half-life: amphetamine (d-isomer) 9-11 hours, l-isomer 11-14 hours; allows for once-daily dosing in extended-release formulation
Approximately 30-40% of a dose is excreted unchanged in urine; the remainder is metabolized primarily by oxidative deamination and aromatic hydroxylation. Biliary/fecal elimination accounts for less than 5%.
Renal (80-90% as unchanged drug and metabolites, primarily dehydro-amphetamine); fecal excretion minimal (<5%)
