ADZENYS ER vs FOCALIN XR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADZENYS ER is a central nervous system (CNS) stimulant that blocks the reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their concentrations in the synaptic cleft.
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.
Adults: Initial 5-10 mg orally once daily; titrate in 5-10 mg increments weekly to optimal response; max 60 mg/day.
Initial 20 mg orally once daily; may increase in 10-20 mg increments at weekly intervals; maximum 60 mg/day.
