ADDERALL XR 15 vs DYANAVEL XR 10
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADDERALL XR contains a mixture of amphetamine salts, including dextroamphetamine and levoamphetamine. The mechanism of action involves increasing synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and enhancing their release from presynaptic terminals, leading to CNS stimulation.
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.
Oral, 20-60 mg once daily in the morning; initial dose 20 mg once daily, titrated by 10-20 mg weekly based on tolerability and efficacy.
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 of amphetamine in adults is approximately 10-13 hours; in children, it is slightly shorter (6-8 hours). For the l-amphetamine isomer, the half-life is 9-11 hours. The extended-release formulation provides a prolonged duration of effect due to a biphasic release profile.
12 hours (amphetamine); clinical context: extended-release profile allows once-daily dosing
Renal: approximately 90% of a dose is excreted in urine, with about 30% as unchanged amphetamine and the remainder as metabolites including deaminated and oxidized products; fecal excretion accounts for less than 10%.
Renal (80-90% as unchanged drug); fecal (minor, 1-5%)
