AMPHETAMINE vs DYANAVEL XR 10
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amphetamine is a central nervous system stimulant that promotes release of monoamines (dopamine, norepinephrine, and serotonin) from presynaptic terminals and inhibits their reuptake, leading to increased synaptic concentrations. It also reversibly inhibits monoamine oxidase (MAO) and may directly stimulate postsynaptic receptors.
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.
5-60 mg/day orally, divided into 2-3 doses; immediate-release: initial 5 mg once or twice daily, increase by 5 mg increments weekly; extended-release: initial 20 mg once daily in the morning, increase by 10 mg weekly
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.

Terminal elimination half-life: 10-13 hours (adults) for immediate-release formulations; prolonged to 12-14 hours in chronic use. Clinical context: Half-life correlates with duration of action; twice-daily dosing may be needed.
12 hours (amphetamine); clinical context: extended-release profile allows once-daily dosing
Primarily renal (70-80% as unchanged drug and metabolites); minor biliary/fecal (approximately 2-5%). Urinary pH-dependent: acidic pH enhances elimination, alkaline pH reduces it.
Renal (80-90% as unchanged drug); fecal (minor, 1-5%)
