CYLERT vs DEXEDRINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CNS stimulant; increases extracellular dopamine and norepinephrine levels by blocking their reuptake and enhancing release.
Dextroamphetamine is a central nervous system stimulant that enhances the activity of dopamine and norepinephrine in the brain by blocking their reuptake and increasing their release from presynaptic terminals.
37.5 mg orally once daily in the morning; may increase by 18.75 mg weekly to a maximum of 112.5 mg/day.
5–60 mg/day orally in divided doses, typically 5–20 mg 1–3 times daily; use immediate-release or extended-release formulations per indication.

Terminal elimination half-life is 12-30 hours in children (mean 19 hours) and 8-14 hours in adults; the long half-life supports once-daily dosing, but accumulation can occur with repeated dosing
Terminal elimination half-life is 4-6 hours for dextroamphetamine; clinical effects last longer due to CNS accumulation
Primarily renal (80-90% as unchanged drug and metabolites, with 50-60% as unchanged pemoline), minor biliary/fecal elimination (<10%)
Renal: 30-45% unchanged, 50-60% as deaminated metabolites; fecal: minor (<5%)
