ADHANSIA XR vs DESOXYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adhansia XR is a central nervous system (CNS) stimulant. The mechanism of action in attention deficit hyperactivity disorder (ADHD) is not fully known, but it is thought to involve blockade of norepinephrine and dopamine reuptake into presynaptic neurons, increasing their levels in the synaptic cleft. This enhances attention and reduces impulsivity.
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.
Methylphenidate hydrochloride extended-release: Oral, 18-72 mg once daily in the morning.
Adults: 5-60 mg/day orally in divided doses, typically starting at 5 mg twice daily; maximum 60 mg/day.

Mean terminal elimination half-life is 7.5 hours (range 5-10 hours) following oral administration, allowing twice-daily dosing.
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.
Primarily renal (78% as unchanged drug), with 10% biliary/fecal elimination.
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.
