Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Adderall 10 contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote the release of dopamine and norepinephrine from presynaptic neurons, inhibit their reuptake, and inhibit monoamine oxidase activity, thereby increasing extracellular levels of these neurotransmitters in the central nervous system.
Calcium disodium edetate chelates heavy metals (e.g., lead, cadmium) forming stable, water-soluble complexes that are excreted renally, reducing metal burden and toxicity.
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
Treatment of lead poisoning (including symptomatic and asymptomatic patients with blood lead levels ≥45 μg/d L in children and ≥70 μg/d L in adults),Off-label: treatment of other heavy metal toxicities (e.g., cadmium, chromium, manganese, nickel)
10 mg orally once daily in the morning, with or without food; may increase by 5-10 mg weekly based on tolerability and response; usual effective dose 10-40 mg/day divided into 2-3 doses; maximum 60 mg/day.
1-2 g intramuscularly or intravenously every 12 hours for 3-5 days, followed by 2-5 days off, repeating as needed.
Terminal elimination half-life: dextroamphetamine 9-11 hours, levoamphetamine 11-14 hours (Adderall is a mixed salt). In adults, mean half-life ~10 hours; in children, slightly shorter (6-8 hours). Clinical context: steady-state reached in 2-3 days; dosing interval typically 4-6 hours for immediate-release.
Terminal elimination half-life: 20-30 minutes for unchelated drug; lead-chelate complex half-life: 1-2 hours. Clinical context: Short half-life necessitates continuous or repeated dosing for sustained chelation.
Amphetamine is metabolized primarily in the liver via cytochrome P450 enzymes, including CYP2D6, and undergoes deamination and oxidation to form inactive metabolites including 4-hydroxyamphetamine and norephedrine.
Not metabolized; excreted unchanged in urine via glomerular filtration and tubular secretion.
Renal: 70-80% (30-40% as unchanged amphetamine; remainder as deaminated and hydroxylated metabolites). Fecal: minimal (<5%). Biliary: negligible. Urinary p H affects excretion: acidic urine increases elimination, alkaline urine decreases.
Renal: >95% as chelated lead complex; biliary/fecal: negligible (<5%)
Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.
<5% bound to plasma proteins (albumin)
Apparent Vd: 3.0-4.0 L/kg (for total amphetamine). High Vd indicates extensive tissue distribution, including brain. Clinical meaning: loading dose may be needed for rapid effect; distribution half-life ~1 hour.
0.2-0.3 L/kg; primarily distributes to extracellular fluid, minimal intracellular penetration
Oral immediate-release: 100% (well-absorbed; first-pass metabolism minimal). Food delays absorption but does not affect extent. Extended-release: bioavailability similar to immediate-release with modified release profile.
IV: 100%; IM: approximately 80-90% (due to local chelation and partial excretion)
e GFR 15-29 m L/min: reduce dose by 50% and monitor for toxicity; e GFR <15 m L/min or dialysis: avoid use due to risk of accumulation; consider alternative therapy.
GFR > 50 m L/min: no adjustment; GFR 10-50 m L/min: administer 50% of usual dose; GFR < 10 m L/min: administer 25% of usual dose or consider alternative therapy.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use due to decreased clearance and increased risk of toxicity.
No specific guidelines available; use with caution and monitor liver function in severe hepatic impairment (Child-Pugh C).
Children 3-5 years: 2.5 mg orally once daily; may increase by 2.5 mg weekly; usual range 2.5-20 mg/day divided 1-2 times. Children 6 years and older: initial 5 mg once daily; may increase by 5 mg weekly; usual range 5-40 mg/day divided 1-3 times; maximum 40 mg/day.
25 mg/kg/dose intramuscularly or intravenously every 12 hours for 3-5 days; maximum 1 g/dose.
Initiate at 2.5-5 mg orally once daily; titrate slowly in increments of 2.5-5 mg weekly; monitor for cardiovascular effects, insomnia, and weight loss; maximum 40 mg/day.
Consider renal function; elderly patients often require dose reduction based on creatinine clearance; start at lower end of dosing range and monitor for adverse effects.
Potential for abuse and dependence. Amphetamines have a high potential for abuse, which may lead to dependence and serious cardiovascular adverse events. Misuse may cause sudden death and serious cardiovascular events.
This drug is not indicated for the treatment of iron deficiency anemia or hemochromatosis. Do not use in patients with severe renal impairment. Prolonged or excessive use may lead to toxicities including renal failure, convulsions, and cardiac arrhythmias.
Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities or other serious heart problems.,Blood pressure and heart rate increase; caution in hypertension and other cardiovascular conditions.,Psychiatric adverse events including exacerbation of psychosis, mania, and aggression.,Long-term suppression of growth in pediatric patients.,Peripheral vasculopathy including Raynaud's phenomenon.,Seizures: may lower seizure threshold.,Serotonin syndrome risk when co-administered with serotonergic drugs.
Renal toxicity: monitor renal function and urine output; avoid excessive doses. Neurotoxicity: can cause tremors, seizures, and encephalopathy, especially with high doses or rapid infusion. Hydration: maintain adequate hydration to promote urinary excretion. Rebound metal mobilization: may transiently increase tissue metal levels. Hypocalcemia: due to calcium displacement; monitor serum calcium. Cardiac effects: risk of arrhythmias, especially with rapid IV administration.
Advanced arteriosclerosis,Symptomatic cardiovascular disease,Moderate to severe hypertension,Hyperthyroidism,Known hypersensitivity or idiosyncrasy to sympathomimetic amines,Glaucoma,Agitated states,History of drug abuse,During or within 14 days following the administration of monoamine oxidase inhibitors (hypertensive crises may occur)
Absolute: anuria or severe renal failure (creatinine clearance <20 m L/min). Relative: hypersensitivity to edetate salts, pre-existing renal disease, concurrent use with other nephrotoxic drugs.
High-fat meals can delay absorption; avoid acidic foods (e.g., citrus, cola) within 1 hour of dosing as they decrease absorption. Avoid caffeine; may increase stimulant effects.
Avoid excessive intake of calcium and vitamin D supplements during therapy (may reduce chelation efficacy). Maintain adequate hydration with water. No specific food restrictions, but a balanced diet is recommended to prevent deficiencies of essential minerals (zinc, copper) that may be chelated.
Pregnancy Category C. First trimester: potential increased risk of congenital malformations (e.g., gastroschisis, oral clefts) based on limited human data. Second and third trimesters: risk of fetal growth restriction, preterm delivery, and neonatal withdrawal symptoms (irritability, poor feeding).
Limited human data. Animal studies show fetal toxicity at high doses. First trimester: theoretical risk of chelation of essential minerals. Second and third trimesters: risk of fetal zinc/corper deficiency if prolonged use. Avoid unless maternal benefit outweighs risk.
Excreted into breast milk; relative infant dose estimated at 2-4% of maternal weight-adjusted dose. M/P ratio not well established. Manufacturer recommends caution; potential for infant agitation, insomnia, and growth suppression.
Excreted into breast milk in low amounts; M/P ratio unknown. Caution due to potential for infant mineral chelation. Use only if clearly needed.
Increased plasma volume and enhanced hepatic metabolism may reduce amphetamine levels; dose adjustments should be individualized based on clinical response, but controlled studies lacking. Avoid abrupt discontinuation due to risk of withdrawal symptoms in mother and neonate.
No specific dose adjustment required; however, monitor for hypocalcemia and mineral depletion. Increased risk of renal toxicity in pregnancy; ensure adequate hydration.
Adderall 10 mg contains immediate-release amphetamine salts. Onset of action is 30-60 minutes, duration 4-6 hours. Monitor for appetite suppression, insomnia, and cardiovascular effects. Avoid in patients with structural cardiac abnormalities or history of substance abuse. Use with caution in hypertension or hyperthyroidism. Drug holidays may reduce tolerance.
Administer deep IM or slow IV infusion (over 2-4 hours) to avoid thrombophlebitis. Monitor urine output and renal function; nephrotoxicity is dose-dependent. Discontinue if oliguria or rising creatinine occurs. For lead encephalopathy, give concurrently with BAL (dimercaprol) to redistribute lead from CNS to blood. Use with caution in patients with pre-existing renal disease, hepatitis, or history of allergic reactions. EDTA can chelate essential metals (zinc, copper) leading to deficiencies during prolonged therapy.
Take exactly as prescribed; do not crush or chew tablets.,Take early in the day to prevent insomnia.,May cause weight loss; monitor growth in children.,Avoid alcohol and decongestants (risk of hypertensive crisis).,Report chest pain, palpitations, or shortness of breath immediately.,Do not drive if you feel dizzy or impaired.
