EVEKEO vs ADDERALL 30
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
Treatment of acute cyanide poisoning,Off-label: Prevention of cyanide toxicity from sodium nitroprusside infusion
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
5 mg IV infused over 1 hour every 2 weeks until disease progression or unacceptable toxicity. Reduce dose for adverse reactions.
Initial: 5 mg orally once or twice daily; increase by 5 mg increments weekly; usual maintenance: 20-30 mg daily in divided doses; maximum: 40 mg/day
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.
Terminal elimination half-life: d-amphetamine 10-13 hours, l-amphetamine 13-15 hours; in adults (children: 6-8 hours). The longer half-life allows for once-daily dosing.
Sodium nitrite is metabolized primarily to methemoglobin and nitric oxide. Sodium thiosulfate is metabolized to thiocyanate by rhodanese.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Renal: 30-50% as unchanged drug; fecal: 50-70% as metabolites and unchanged drug.
Approximately 30-40% of a dose is excreted unchanged in urine; the remainder is metabolized primarily by oxidative deamination and aromatic hydroxylation. Biliary/fecal elimination accounts for less than 5%.
40-50% bound to serum albumin and α1-acid glycoprotein.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
0.6-0.8 L/kg. Clinical meaning: Moderate distribution suggests limited tissue penetration; primarily confined to extracellular fluid.
Vd: 3-4 L/kg (approximately 210-280 L for a 70 kg adult). This indicates extensive tissue distribution and penetration into the central nervous system.
Oral: 85-95%. Rectal: 70-80%. Intramuscular: 90-100%.
Oral immediate-release: approximately 75-100%; oral extended-release: approximately 94% relative to immediate-release. Food does not significantly affect absorption but may delay peak concentration.
No adjustment required for mild to moderate renal impairment (Cr Cl ≥30 m L/min). Not recommended for severe renal impairment (Cr Cl <30 m L/min) due to limited data.
GFR 30-89 m L/min: no adjustment; GFR 15-29 m L/min: reduce dose by 50%; GFR <15 m L/min: avoid use
No adjustment required for mild hepatic impairment (Child-Pugh A). Not recommended for moderate or severe hepatic impairment (Child-Pugh B or C) due to limited data.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use
Not approved for pediatric patients; safety and efficacy not established.
Children 3-5 years: initial 2.5 mg orally once daily; increase by 2.5 mg weekly; usual range 2.5-20 mg/day. Children ≥6 years: initial 5 mg once or twice daily; increase by 5 mg weekly; usual range 5-40 mg/day in divided doses
No specific dose adjustment recommended; clinical studies included patients ≥65 years with no overall differences in safety or efficacy.
Initiate at 2.5 mg orally once or twice daily; titrate slowly; monitor for cardiovascular effects, insomnia, and weight loss
Risk of severe hypotension and methemoglobinemia. Monitor methemoglobin levels. Use caution in patients with low oxygen saturation.
Amphetamines have a high potential for abuse and dependence. Misuse may cause sudden death or serious cardiovascular events.
Can cause severe hypotension requiring vasopressors,Methemoglobinemia may reduce oxygen delivery; avoid in patients with significant anemia or G6PD deficiency,Thiocyanate accumulation with prolonged use, especially in renal impairment
Risk of serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities,Increased blood pressure and heart rate,Psychiatric adverse events including exacerbation of pre-existing psychosis, mania, or aggressive behavior,Serotonin syndrome risk when co-administered with serotonergic drugs,Long-term suppression of growth in children,Seizure risk in patients with history of seizures,Peripheral vasculopathy including Raynaud's phenomenon,Visual disturbances due to mydriasis
Hypersensitivity to sodium nitrite or sodium thiosulfate,Methemoglobin reductase deficiency
Advanced arteriosclerosis,Symptomatic cardiovascular disease,Moderate to severe hypertension,Hyperthyroidism,Known hypersensitivity to amphetamines,Agitated states,History of drug abuse,During or within 14 days of MAO inhibitor use,Glaucoma
No known food interactions. EVEKEO is administered intravenously and is not affected by oral intake. However, in neonates, careful monitoring of electrolyte and fluid balance is important.
Avoid high-fat meals as they delay absorption; avoid acidic foods (e.g., citrus) and vitamin C supplements within 1 hour of dosing as they decrease absorption; limit caffeine and other stimulants to avoid additive cardiovascular effects.
Pregnancy Category N (not assigned). No adequate human data; based on animal studies, fetal harm is possible. Avoid use in first trimester if alternative available. Risk in second and third trimesters unknown.
Pregnancy category C. First trimester: No well-controlled studies, but potential for congenital malformations not definitively established. Second and third trimesters: Increased risk of premature delivery, low birth weight, and neonatal withdrawal symptoms (e.g., dysphoria, agitation, lassitude). Chronic use may lead to neonatal toxicity.
No data on excretion in human milk. M/P ratio unknown. Caution if breastfeeding; consider risk vs benefit.
Excreted in breast milk. M/P ratio unknown. Potential for stimulant effects in infant (e.g., irritability, poor feeding, insomnia). Caution advised; consider alternative feeding methods.
No pharmacokinetic studies in pregnancy; dose adjustment recommendations not established. Use lowest effective dose and shortest duration.
No established dosing guidelines. Due to increased plasma volume and clearance, dose may need titration to clinical effect, but avoid supratherapeutic doses. Use lowest effective dose.
EVEKEO is a beta-adrenergic agonist indicated for the treatment of bradycardia in premature neonates. It is given intravenously and has a rapid onset of action (1-2 minutes). Monitor heart rate and blood pressure continuously during infusion. Use with caution in patients with hyperthyroidism, diabetes, or history of seizures. Tachyphylaxis may develop with prolonged use.
For ADHD: start low, go slow; monitor weight and height in children; avoid late doses to prevent insomnia; check for abuse/diversion; screen for bipolar disorder and hypertension; consider urine drug screen before prescribing; avoid MAOIs within 14 days; use with caution in seizure disorders and glaucoma.
