ADZENYS XR-ODT vs JORNAY PM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adzenys XR-ODT contains amphetamine, a central nervous system stimulant that increases extracellular levels of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals.
Methylphenidate is a central nervous system (CNS) stimulant. The mode of action in attention deficit hyperactivity disorder (ADHD) is not fully understood, but methylphenidate is thought to block the reuptake of norepinephrine and dopamine into the presynaptic neuron, increasing the levels of these neurotransmitters in the extraneuronal space.
Initial: 9.4 mg orally once daily in the morning; titrate in increments of 9.4 mg per week based on tolerability and response. Maximum: 56.4 mg once daily.
Initial: 20 mg orally once daily at bedtime; increase by 20 mg weekly as needed; max 100 mg/day.

Approximately 9-14 hours in adults, 8-11 hours in children (6-12 years). Extended-release pharmacokinetics produce a longer clinical duration compared to immediate-release formulations.
The terminal elimination half-life of methylphenidate following JORNAY PM administration is approximately 4-5 hours. This relatively short half-life necessitates the delayed-release/extended-release formulation to provide a prolonged duration of effect.
Renal: approximately 90% as unchanged drug and metabolites (30%-40% as amphetamine, 40%-50% as hippuric acid and benzoic acid). Fecal: <4%. Biliary: negligible.
Methylphenidate and its metabolites are primarily excreted in urine (approximately 90%) as metabolites (mainly ritalinic acid) with about 2% unchanged parent drug. Fecal excretion accounts for <1%.
