ADZENYS XR-ODT vs AMPHETAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adzenys XR-ODT contains amphetamine, a central nervous system stimulant that increases extracellular levels of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals.
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.
Initial: 9.4 mg orally once daily in the morning; titrate in increments of 9.4 mg per week based on tolerability and response. Maximum: 56.4 mg once daily.
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

Clinical Note
moderateAmphetamine + Torasemide
"Amphetamine may increase the hypotensive activities of Torasemide."
Clinical Note
moderateAmphetamine + Tranilast
"Amphetamine may decrease the sedative activities of Tranilast."
Clinical Note
moderateHydroxyamphetamine + Tranilast
"Hydroxyamphetamine may decrease the sedative activities of Tranilast."
Clinical Note
moderateDextroamphetamine + Tranilast
"Dextroamphetamine may decrease the sedative activities of Tranilast."
Approximately 9-14 hours in adults, 8-11 hours in children (6-12 years). Extended-release pharmacokinetics produce a longer clinical duration compared to immediate-release formulations.
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.
Renal: approximately 90% as unchanged drug and metabolites (30%-40% as amphetamine, 40%-50% as hippuric acid and benzoic acid). Fecal: <4%. Biliary: negligible.
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.
