DAYTRANA vs FOCALIN 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.
Focalin XR (dexmethylphenidate) is a central nervous system stimulant. It blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their concentrations in the synaptic cleft. The d-threo enantiomer is pharmacologically active.
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 20 mg orally once daily; may increase in 10-20 mg increments at weekly intervals; maximum 60 mg/day.

Terminal half-life in children is approximately 5–6 hours; in adults, approximately 5 hours; wears off within 12 hours of patch removal.
Terminal half-life: 2-3 hours for immediate-release; 6-8 hours for extended-release (FOCALIN XR)
Renal (approx. 78% unchanged) and fecal (approx. 10%); remainder as metabolites.
