DYANAVEL XR 10 vs JORNAY PM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dyanavel XR is a central nervous system stimulant that increases extracellular levels of dopamine and norepinephrine by inhibiting their reuptake and enhancing their release from presynaptic neurons.
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.
Recommended starting dose for adults is 10 mg orally once daily in the morning. May increase in increments of 5-10 mg at weekly intervals based on tolerability and response. Maximum recommended dose is 60 mg/day.
Initial: 20 mg orally once daily at bedtime; increase by 20 mg weekly as needed; max 100 mg/day.

12 hours (amphetamine); clinical context: extended-release profile allows once-daily dosing
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 (80-90% as unchanged drug); fecal (minor, 1-5%)
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%.
