DESOXYN vs DEXTROSTAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Desoxyn (methamphetamine) is a sympathomimetic amine that promotes release of catecholamines (primarily dopamine and norepinephrine) from presynaptic nerve terminals, blocks their reuptake, and inhibits monoamine oxidase (MAO) activity. It produces CNS stimulation and peripheral alpha- and beta-adrenergic effects.
Dextroamphetamine is a central nervous system stimulant that promotes release of dopamine and norepinephrine from presynaptic neurons, and inhibits their reuptake, thereby increasing synaptic concentrations of these neurotransmitters.
Adults: 5-60 mg/day orally in divided doses, typically starting at 5 mg twice daily; maximum 60 mg/day.
5-60 mg orally per day in divided doses, typically 5-10 mg 2-3 times daily, maximum 60 mg/day.

Terminal elimination half-life: 9–14 hours (mean 12 hours) in adults; prolonged in alkaline urine (up to 25–30 hours). Clinically, twice-daily dosing maintains steady state after 2–3 days.
Terminal elimination half-life is approximately 10-13 hours in adults, 6-8 hours in children. Extended duration allows once-daily dosing in some patients.
Renal: ~90% as unchanged drug and metabolites (primarily 4-hydroxyephedrine and 4-hydroxynorephedrine) within 48 hours; urinary pH-dependent: acidic urine increases elimination. Biliary/fecal: minor.
Primarily renal (approximately 90% as unchanged drug and metabolites); minor biliary/fecal elimination (<10%).
