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.
Selective serotonin reuptake inhibitor (SSRI); inhibits serotonin reuptake at the presynaptic neuron, potentiating serotonergic activity.

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.
10 mg orally once daily; may increase to 20 mg once daily after at least 1 week.
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.
27-32 hours (mean ~30 h); steady state reached in ~1 week; linear kinetics at therapeutic doses.
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.
Primarily hepatic via CYP3A4 and CYP2C19; active metabolite S-desmethylcitalopram.
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.
Primarily renal (approx. 80% as metabolites, 8% as unchanged drug); biliary/fecal elimination accounts for ~15%.
Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.
Approximately 56% bound to plasma proteins (mainly albumin and alpha-1-acid glycoprotein).
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.
12-26 L/kg (mean ~20 L/kg); extensive extravascular distribution consistent with high lipophilicity.
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.
Oral: approximately 80% (range 60-90%) after a single dose; food does not significantly affect absorption.
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.
No dosage adjustment for mild to moderate impairment. Not recommended for severe impairment (Cr Cl <20 m L/min).
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.
For Child-Pugh class A or B: 10 mg orally once daily. Use caution in severe impairment (Child-Pugh class C); limited data.
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.
Adolescents 12-17 years: 10 mg orally once daily. Children <12 years: not approved.
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.
Initial 5 mg orally once daily; maximum 10 mg once daily.
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.
Increased risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder and other psychiatric disorders.
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.
Suicidality risk in young adults,Serotonin syndrome,QT prolongation,Hyponatremia,Bleeding risk,Activation of mania/hypomania,Seizure risk,Abrupt discontinuation syndrome
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)
Concurrent use of MAOIs or within 14 days of discontinuing MAOI,Concomitant use of pimozide,Hypersensitivity to escitalopram or citalopram,QT prolongation or congenital long QT syndrome (for citalopram, caution for escitalopram)
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.
Grapefruit juice may increase escitalopram exposure; avoid concurrent use. Alcohol can potentiate central nervous system depression; limit or avoid alcohol consumption. No significant food interactions; may be taken with or without food.
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).
First trimester: Epidemiologic studies have shown a small increased risk of congenital cardiac defects (primarily ventricular septal defects) with exposure, with an absolute risk of approximately 1-2%. Second/third trimester: Late pregnancy exposure may increase risk for persistent pulmonary hypertension of the newborn (PPHN) and serotonin syndrome in the neonate. Third trimester use may lead to neonatal adaptation syndrome including irritability, respiratory distress, and feeding difficulties.
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.
Escitalopram is excreted into human breast milk with a milk-to-plasma ratio (M/P) of approximately 2.0. Infant serum levels are typically low, but some cases of adverse effects such as irritability, feeding problems, and sleep disturbance have been reported. The American Academy of Pediatrics considers escitalopram compatible with breastfeeding, but caution is advised, especially in premature or compromised infants.
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.
Pharmacokinetic changes during pregnancy (increased volume of distribution, increased clearance) may require dose adjustments. Escitalopram clearance increases by approximately 50% in the third trimester. Dose increases may be needed to maintain efficacy, with gradual reduction postpartum to pre-pregnancy dose over 2-4 weeks. Therapeutic drug monitoring of escitalopram and its metabolite S-DCT is recommended if available, targeting trough levels of 15-80 ng/m L.
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.
LEXAPRO (escitalopram) is the S-enantiomer of citalopram with less cytochrome P450 inhibition, minimizing drug interactions compared to racemic citalopram. QT prolongation risk is dose-dependent; maximum dose is 20 mg/day. Avoid co-administration with MAOIs and other serotonergic drugs due to serotonin syndrome risk. Abrupt discontinuation may cause withdrawal symptoms; taper over 1-2 weeks. Onset of therapeutic effect is 2-4 weeks. Use with caution in hepatic impairment (max dose 10 mg) and elderly patients.
