DYANAVEL XR vs EVEKEO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dyanavel XR is a central nervous system stimulant that increases the levels of dopamine and norepinephrine in the synaptic cleft by inhibiting their reuptake and increasing their release, thereby enhancing neurotransmission in the brain regions involved in attention and impulse control.
EVEKEO (sodium nitrite and sodium thiosulfate) is a cyanide antidote. Sodium nitrite induces methemoglobin formation, which binds free cyanide. Sodium thiosulfate provides a sulfur donor for conversion of cyanide to thiocyanate via rhodanese.
Initial dose: 5 mg orally once daily in the morning. Maximum dose: 20 mg once daily. May increase by 5–10 mg weekly based on tolerability and response.
5 mg IV infused over 1 hour every 2 weeks until disease progression or unacceptable toxicity. Reduce dose for adverse reactions.

Mean terminal elimination half-life is approximately 8-10 hours for d-amphetamine and 12-14 hours for l-amphetamine; the extended-release formulation maintains therapeutic concentrations for 12-14 hours.
Terminal elimination half-life: 2-3 hours. Clinical context: Short half-life supports multiple daily dosing for seizure control. May be prolonged in hepatic impairment.
Approximately 30-50% of a dose is excreted unchanged in urine; remainder as metabolites (primarily hippuric acid) via renal elimination. Fecal excretion is minimal.
Renal: 30-50% as unchanged drug; fecal: 50-70% as metabolites and unchanged drug.
