DYANAVEL XR 15 vs EVEKEO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dyanavel XR contains amphetamine, which is a central nervous system stimulant that increases synaptic concentrations of dopamine and norepinephrine by inhibiting their reuptake and promoting their release from presynaptic terminals.
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.
1-3 capsules orally once daily in the morning. Each capsule contains 15 mg of amphetamine (equivalent to 15 mg dextroamphetamine/amphetamine).
5 mg IV infused over 1 hour every 2 weeks until disease progression or unacceptable toxicity. Reduce dose for adverse reactions.

Terminal elimination half-life: amphetamine (d-isomer) 9-11 hours, l-isomer 11-14 hours; allows for once-daily dosing in extended-release formulation
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.
Renal (80-90% as unchanged drug and metabolites, primarily dehydro-amphetamine); fecal excretion minimal (<5%)
Renal: 30-50% as unchanged drug; fecal: 50-70% as metabolites and unchanged drug.
