ADDERALL 7.5 vs ADHANSIA XR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADDERALL 7.5 is a combination of amphetamine and dextroamphetamine, which are non-catecholamine sympathomimetic amines with CNS stimulant activity. The mechanism of action involves blocking the reuptake of norepinephrine and dopamine into presynaptic neurons, as well as increasing their release into the extraneuronal space. This leads to increased levels of these neurotransmitters in the synaptic cleft, enhancing stimulation of postsynaptic receptors.
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.
5-20 mg orally 1-3 times daily; immediate-release tablets administered upon awakening and at 4-6 hour intervals as needed; extended-release capsules administered once daily upon awakening; maximum total daily dose 40 mg.
Methylphenidate hydrochloride extended-release: Oral, 18-72 mg once daily in the morning.

The terminal elimination half-life of amphetamine is approximately 10-13 hours in adults, but can vary based on urinary pH (alkaline urine prolongs half-life up to 20 hours; acidic urine reduces it to 7-8 hours). In children, half-life is slightly shorter (6-8 hours). Clinical context: Steady-state is achieved within 2-3 days.
Mean terminal elimination half-life is 7.5 hours (range 5-10 hours) following oral administration, allowing twice-daily dosing.
Renal: approximately 90% of a dose is excreted in urine, with about 30% as unchanged amphetamine and the remainder as metabolites (including deaminated and hydroxylated products). Fecal excretion is negligible (<5%).
Primarily renal (78% as unchanged drug), with 10% biliary/fecal elimination.
