Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Chelates copper, forming a stable complex that is excreted renally, reducing systemic copper accumulation.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
Wilson disease,Cystinuria,Rheumatoid arthritis (off-label)
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
250-500 mg orally 4 times daily, titrated to maintain urinary copper excretion >2 mg/day. Maximum: 2 g/day.
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 half-life: 4–6 hours. Clinical context: After discontinuation, urinary copper excretion declines within 2–3 hours but may persist for several days due to tissue redistribution.
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.
Metabolized by oxidation and reduction; primarily renal elimination.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Renal: ~80% as unchanged drug, biliary/fecal: <5%
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%.
~70% bound, primarily to serum albumin.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
Vd: 0.5–1.0 L/kg (approximately 70 L in adults). Indicates distribution into total body water with moderate tissue binding.
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: Approximately 40–70% (variable, reduced by food, especially high-protein meals; administration on empty stomach recommended).
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.
Contraindicated in severe renal impairment (GFR <30 m L/min). For GFR 30-60 m L/min: reduce dose by 25-50%. Monitor urinary copper and adjust accordingly.
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 specific adjustment for Child-Pugh class A or B; use with caution in severe hepatic impairment (Child-Pugh C) due to hepatotoxicity risk. Monitor liver function.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use
10-20 mg/kg/day orally divided into 2-4 doses; typical starting dose 15 mg/kg/day for Wilson disease (max 1 g/day). Titrate based on urinary copper.
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
Start at lower end of dosing range (250 mg twice daily) due to age-related renal decline; monitor renal function and copper levels.
Initiate at 2.5 mg orally once or twice daily; titrate slowly; monitor for cardiovascular effects, insomnia, and weight loss
WARNING: CUPRIMINE can cause severe bone marrow depression leading to aplastic anemia, leukopenia, thrombocytopenia, and agranulocytosis. Deaths have occurred. Monitor blood counts closely.
Amphetamines have a high potential for abuse and dependence. Misuse may cause sudden death or serious cardiovascular events.
Bone marrow suppression, renal toxicity (proteinuria, hematuria), lupus-like syndrome, myasthenia gravis-like syndrome, rash, and hypersensitivity reactions. Monitor renal function, blood counts, and urinalysis regularly.
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
History of penicillamine-related aplastic anemia or agranulocytosis; concurrent gold therapy, antimalarial drugs, or immunosuppressants; rheumatoid arthritis patients with renal insufficiency.
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
Take on an empty stomach. Avoid food, especially milk, and any mineral supplements (iron, zinc, calcium) for at least 1 hour before and 2 hours after dosing, as they reduce absorption. Alcohol should be avoided due to potential hepatotoxicity.
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.
First trimester: High risk of congenital anomalies including cutis laxa, micrognathia, limb deformities, and CNS defects. Second trimester: Continued risk of fetal harm, potential for growth restriction. Third trimester: Risk of fetal copper deficiency and associated neurological impairment. Pregnancy category D.
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.
Excreted in breast milk. M/P ratio not established. Contraindicated in breastfeeding due to potential for severe adverse effects (hypersensitivity, bone marrow suppression) in the infant.
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 standard dose adjustment recommended; use lowest effective dose. Monitor serum copper to maintain therapeutic levels due to altered pharmacokinetics in pregnancy (increased volume of distribution, renal clearance).
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.
Monitor for proteinuria and hematuria; perform urinalysis weekly initially, then monthly. Penicillamine can cause bone marrow suppression; obtain baseline CBC and differential, then monitor every 2 weeks for first 6 months, then monthly. Drug-induced lupus and myasthenia gravis are rare but serious autoimmune adverse effects. Avoid in patients with a history of penicillin allergy due to potential cross-sensitivity. Administer on an empty stomach at least 1 hour before or 2 hours after meals to enhance absorption. Dose adjustments needed in renal impairment. Pyridoxine (vitamin B6) supplementation (25-50 mg/day) is recommended to prevent deficiency caused by penicillamine. For Wilson disease, monitor 24-hour urinary copper excretion to guide therapy.
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.
