DEXMETHYLPHENIDATE HYDROCHLORIDE vs EVEKEO ODT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
EVEKEO ODT (amphetamine) is a CNS stimulant that increases extracellular levels of dopamine and norepinephrine by blocking their reuptake into presynaptic neurons and inhibiting monoamine oxidase, leading to enhanced neurotransmission.
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).
0.25 mg orally as a single dose; may repeat once after 30 minutes if required.
