ADDERALL XR 10 vs DYANAVEL XR 15
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adderall XR 10 contains a mixture of amphetamine salts, which are central nervous system stimulants. The dextroamphetamine and levoamphetamine components increase synaptic concentrations of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals. This action leads to enhanced neurotransmission in the prefrontal cortex and other brain regions involved in attention and executive function.
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.
10 mg orally once daily in the morning; maximum dose 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).

Dexamphetamine: 10-13 hours in adults (children: 6-8 hours); levoamphetamine: 13-16 hours; clinically, steady-state achieved in approximately 3 days, with twice-daily dosing maintaining therapeutic levels
Terminal elimination half-life: amphetamine (d-isomer) 9-11 hours, l-isomer 11-14 hours; allows for once-daily dosing in extended-release formulation
Renal (approximately 30-40% as unchanged amphetamine, remainder as metabolites, including deaminated and oxidized products; urinary pH-dependent elimination: acidic pH increases renal clearance, alkaline pH decreases renal clearance; negligible biliary/fecal elimination)
Renal (80-90% as unchanged drug and metabolites, primarily dehydro-amphetamine); fecal excretion minimal (<5%)
