ADHANSIA XR vs AMPHETAMINE
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.
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.
Methylphenidate hydrochloride extended-release: Oral, 18-72 mg once daily in the morning.
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

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