DAYTRANA vs DYANAVEL XR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylphenidate is a central nervous system stimulant that blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their extracellular concentrations.
Dyanavel XR is a central nervous system stimulant that increases the levels of dopamine and norepinephrine in the synaptic cleft by inhibiting their reuptake and increasing their release, thereby enhancing neurotransmission in the brain regions involved in attention and impulse control.
Initial: 10 mg transdermal patch applied to hip for 9 hours daily; may titrate weekly in increments of 5 mg to a maximum of 30 mg/day.
Initial dose: 5 mg orally once daily in the morning. Maximum dose: 20 mg once daily. May increase by 5–10 mg weekly based on tolerability and response.

Terminal half-life in children is approximately 5–6 hours; in adults, approximately 5 hours; wears off within 12 hours of patch removal.
Mean terminal elimination half-life is approximately 8-10 hours for d-amphetamine and 12-14 hours for l-amphetamine; the extended-release formulation maintains therapeutic concentrations for 12-14 hours.
Renal (approx. 78% unchanged) and fecal (approx. 10%); remainder as metabolites.
Approximately 30-50% of a dose is excreted unchanged in urine; remainder as metabolites (primarily hippuric acid) via renal elimination. Fecal excretion is minimal.
