ADZENYS ER vs DEXMETHYLPHENIDATE HYDROCHLORIDE
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.
Dexmethylphenidate is a central nervous system (CNS) stimulant. Its mechanism of action in ADHD is not fully understood, but it is believed to block the reuptake of norepinephrine and dopamine into the presynaptic neuron, increasing their levels in the extraneuronal space.
Adults: Initial 5-10 mg orally once daily; titrate in 5-10 mg increments weekly to optimal response; max 60 mg/day.
Initial: 5 mg orally twice daily (morning and noon) with or without food; titrate in increments of 5 mg weekly; maximum 20 mg twice daily (40 mg/day).
