EVEKEO ODT vs METADATE CD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Methylphenidate is a central nervous system (CNS) stimulant. It blocks the reuptake of norepinephrine and dopamine into the presynaptic neuron, increasing their levels in the extraneuronal space. The precise mechanism for treating ADHD is not fully understood.
0.25 mg orally as a single dose; may repeat once after 30 minutes if required.
20-60 mg orally once daily in the morning

3-5 hours in healthy adults; prolonged in renal impairment (up to 20 hours in ESRD)
Terminal elimination half-life: 6.8 hours (range 4.5-10.3 hours) for methylphenidate; clinical context: supports twice-daily dosing regimen
Renal: approximately 50% as unchanged drug and metabolites; fecal: minimal (<10%)
Renal: 78-97% as metabolites (primarily ritalinic acid), unchanged drug <1%; fecal: <2%
