Clinical Essentials

DYANAVEL XR 5
EVEKEO
Mechanism of Action
DYANAVEL XR 5

CNS stimulant; blocks reuptake of norepinephrine and dopamine into presynaptic neurons, increasing their synaptic concentrations.

EVEKEO

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.

Indications
DYANAVEL XR 5

Attention deficit hyperactivity disorder (ADHD)

EVEKEO

Treatment of acute cyanide poisoning,Off-label: Prevention of cyanide toxicity from sodium nitroprusside infusion

Standard Dosing
DYANAVEL XR 5

20 mg orally once daily in the morning; may increase by 10 mg weekly based on response; maximum 60 mg/day.

EVEKEO

5 mg IV infused over 1 hour every 2 weeks until disease progression or unacceptable toxicity. Reduce dose for adverse reactions.

Pharmacokinetics

DYANAVEL XR 5
EVEKEO
Half-Life
DYANAVEL XR 5

Terminal elimination half-life for d-amphetamine is 10-13 hours; for l-amphetamine, 13-16 hours. Clinical context: Twice-daily dosing may be required for sustained effect.

EVEKEO

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.

Metabolism
DYANAVEL XR 5

Primarily hepatic via carboxylesterase 1 (CES1) to active metabolite dexmethylphenidate; further metabolism by CYP2D6 and carboxylesterases.

Special Populations

EVEKEO
Renal Adjustments
DYANAVEL XR 5

GFR 30-89 m L/min: no adjustment; GFR <30 m L/min: not recommended; hemodialysis: not recommended.

EVEKEO

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.

Hepatic Adjustments
DYANAVEL XR 5

Child-Pugh Class A: no adjustment; Child-Pugh Class B: reduce dose by 50%; Child-Pugh Class C: not recommended.

Safety & Monitoring

DYANAVEL XR 5
EVEKEO
Black Box Warnings
DYANAVEL XR 5
FDA Black Box Warning

WARNING: ABUSE AND DEPENDENCE. CNS stimulants (including DYANAVEL XR) have a high potential for abuse and dependence, which can lead to tolerance and severe psychological dependence. Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy.

Pregnancy & Lactation

DYANAVEL XR 5
EVEKEO
Teratogenic Risk
DYANAVEL XR 5

First trimester: Limited human data; animal studies show teratogenic effects at high doses. Second/third trimester: Increased risk of preterm birth, low birth weight, and withdrawal symptoms. Chronic use may cause neonatal adaptation syndrome (irritability, poor feeding).

EVEKEO

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.

Lactation Summary

EVEKEO
Clinical Pearls
DYANAVEL XR 5

DYANAVEL XR 5 is an extended-release amphetamine suspension indicated for attention deficit hyperactivity disorder. The capsule can be swallowed whole or opened and sprinkled onto applesauce. Administer in the morning to avoid insomnia. Monitor for growth suppression in children and for cardiovascular events in patients with known structural cardiac abnormalities. The prodrug formulation (lisdexamfetamine) is not interchangeable; DYANAVEL XR contains mixed amphetamine salts.

EVEKEO

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.

Clinical Q&A

Frequently Asked Questions

1. What is the primary difference between DYANAVEL XR 5 and EVEKEO?

DYANAVEL XR 5 and EVEKEO are distinct pharmacological agents. DYANAVEL XR 5 belongs to the CNS Stimulant class and is primarily used for Attention deficit hyperactivity disorder (ADHD). EVEKEO belongs to the CNS Stimulant class and is primarily used for Treatment of acute cyanide poisoningOff-label: Prevention of cyanide toxicity from sodium nitroprusside infusion. Their specific mechanisms of action, pharmacokinetic characteristics, and side effects differ.

2. Are DYANAVEL XR 5 and EVEKEO safe during pregnancy?

The maternal-fetal safety profiles of these drugs differ. DYANAVEL XR 5 carries a safety status of Category C, whereas EVEKEO safety is classified as Category C. Consult a board-certified physician or healthcare specialist to establish an accurate, individualized pregnancy risk assessment before starting either therapy.

EVEKEO

Sodium nitrite is metabolized primarily to methemoglobin and nitric oxide. Sodium thiosulfate is metabolized to thiocyanate by rhodanese.

Excretion
DYANAVEL XR 5

Renal: ~90% as unchanged amphetamine and metabolites. Fecal: minimal (<5%).

EVEKEO

Renal: 30-50% as unchanged drug; fecal: 50-70% as metabolites and unchanged drug.

Protein Binding
DYANAVEL XR 5

d-Amphetamine: ~20% bound to albumin and alpha1-acid glycoprotein; l-amphetamine: ~15% bound.

EVEKEO

40-50% bound to serum albumin and α1-acid glycoprotein.

VD (L/kg)
DYANAVEL XR 5

Vd: 3-4 L/kg; indicates extensive tissue distribution.

EVEKEO

0.6-0.8 L/kg. Clinical meaning: Moderate distribution suggests limited tissue penetration; primarily confined to extracellular fluid.

Bioavailability
DYANAVEL XR 5

Oral: Approximately 100% (extended-release formulation provides prolonged absorption).

Food Interactions
DYANAVEL XR 5

Avoid high-fat meals before administration as they may delay absorption. No specific food interactions are documented; however, acidic foods (e.g., citrus juices) may alter amphetamine excretion. Grapefruit has no known interaction. Maintain a balanced diet to mitigate appetite suppression.

EVEKEO

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.

DYANAVEL XR 5

Contraindicated during breastfeeding due to amphetamine excretion into breast milk (M/P ratio ~3.8). Potential for infant stimulation, poor weight gain, and toxicity.

EVEKEO

No data on excretion in human milk. M/P ratio unknown. Caution if breastfeeding; consider risk vs benefit.

Pregnancy Dosing
DYANAVEL XR 5

Due to increased plasma volume and clearance during pregnancy, higher doses may be required; however, use is generally avoided. If necessary, titrate to lowest effective dose with close monitoring of maternal and fetal outcomes.

EVEKEO

No pharmacokinetic studies in pregnancy; dose adjustment recommendations not established. Use lowest effective dose and shortest duration.
