Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Arestocaine hydrochloride is a local anesthetic of the amide type. It stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthesia.
Adderall 15 is a combination of amphetamine and dextroamphetamine, which increase synaptic concentrations of norepinephrine and dopamine by inhibiting their reuptake and promoting their release from presynaptic terminals.

2-5 mg/kg intramuscularly every 60-90 minutes, not to exceed 500 mg total dose in a 12-hour period.
10-20 mg orally once daily in the morning; may increase by 5-10 mg weekly; maximum 40 mg/day.
Terminal elimination half-life is approximately 1.5–2 hours in adults with normal hepatic and renal function; prolonged in hepatic impairment or congestive heart failure.
Mean terminal half-life: d-amphetamine 10 h, l-amphetamine 13 h (range 9-14 h); for ADDERALL 15 (3:1 mix), effective half-life ~11 h; clinical context: dosing interval typically QD-BID.
Primarily metabolized by the liver via hydrolysis by esterases (though it is an amide, it may be partially hydrolyzed) and conjugation. The major metabolic pathways involve CYP1A2 and CYP3A4.
Amphetamine is metabolized primarily by hepatic CYP2D6 and to a lesser extent by CYP2C19 and CYP2C9, with some minor pathways involving dopamine beta-hydroxylase.
Renal excretion of unchanged drug and metabolites; approximately 90% excreted in urine as parent compound and metabolites (60% as unchanged drug, 30% as metabolites), with less than 10% fecal elimination.
Primarily renal (90% as unchanged drug and metabolites; ~30% unchanged, 40% as 4-hydroxyamphetamine and conjugates, 20% as other metabolites); minimal biliary/fecal elimination (<3%).
Approximately 70% bound primarily to alpha-1-acid glycoprotein (AAG) and to a lesser extent albumin.
~16-20%; primarily binds to albumin, with minor binding to alpha-1-acid glycoprotein.
Volume of distribution is 0.8–1.5 L/kg, reflecting extensive tissue distribution; higher in neonates and infants.
Vd: 3.0-4.5 L/kg (range 2.6-5.6); indicates extensive tissue distribution, including brain, with accumulation in kidneys and liver.
Topical: variable, approximately 30–50% absorbed through intact skin; Oral: negligible due to extensive first-pass metabolism (bioavailability <10%); Intravenous: 100%.
Oral: ~76% (range 64-95%) for mixed amphetamine salts; bioavailability reduced by acidic gastric p H and increased with food (Tmax delayed but AUC unchanged).
GFR 30-50 m L/min: reduce dose by 25%; GFR 15-29 m L/min: reduce dose by 50%; GFR <15 m L/min: avoid use.
GFR 15-29 m L/min: reduce dose by 50%; GFR <15 m L/min: contraindicated.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated.
1-3 mg/kg intramuscularly every 60-90 minutes, max 200 mg per dose; maximum cumulative dose 400 mg/12 hours.
Weight-based: <50 kg: 2.5-5 mg once daily; 50-100 kg: 5-10 mg once daily; >100 kg: adult dosing.
Initiate at lowest effective dose (2 mg/kg) due to increased sensitivity and potential for prolonged duration; monitor for adverse effects.
Start at 2.5-5 mg once daily; increase slowly due to increased sensitivity and cardiovascular risk.
There is no FDA black box warning for Arestocaine hydrochloride.
WARNING: ABUSE AND DEPENDENCE. CNS stimulants, including Adderall, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence throughout therapy.
Risk of systemic toxicity if injected intravascularly,Use with caution in patients with hepatic impairment,Use with caution in patients with cardiovascular disease,Risk of methemoglobinemia in patients with glucose-6-phosphate dehydrogenase deficiency
Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities or other serious heart problems,Blood pressure and heart rate increases,Psychiatric adverse events (exacerbation of pre-existing psychosis, manic episodes, aggressive behavior),Seizures (may lower seizure threshold),Peripheral vasculopathy including Raynaud's phenomenon,Serotonin syndrome risk, especially with concomitant serotonergic drugs,Long-term growth suppression in children
Hypersensitivity to amide-type local anesthetics,Severe hypotension,Myasthenia gravis (relative contraindication),Bradycardia
Hypersensitivity to amphetamine or other components,Concurrent use or within 14 days of MAOIs (risk of hypertensive crisis),Glaucoma,Hyperthyroidism,Agitated states,History of drug abuse,Cardiovascular disease (symptomatic, moderate to severe hypertension, advanced arteriosclerosis, structural cardiac abnormalities)
No specific food interactions; avoid hot foods until numbness resolves to prevent burns.
Avoid high-fat meals close to dosing as they may delay absorption. Acidic foods (e.g., citrus, cola, vitamin C) can decrease absorption; take with non-acidic fluids. Avoid alcohol and caffeine-containing products.
Pregnancy Category C. Animal reproduction studies have not been conducted. In first trimester, limited data; potential for adverse effects on fetal development cannot be excluded. In second and third trimesters, risk of placental transfer and fetal bradycardia; use only if clearly needed.
First trimester: Possible increased risk of congenital malformations (cardiac, oral clefts) based on limited human data; animal studies show dose-dependent teratogenicity. Second/third trimesters: Risk of fetal growth restriction, preterm delivery, neonatal withdrawal (irritability, feeding problems), and persistent pulmonary hypertension.
No data on excretion in human milk. M/P ratio unknown. Caution advised; discontinue breastfeeding or drug based on importance of drug to mother.
Present in breast milk; M/P ratio approximately 2.5-7.5. Potential for infant stimulation, insomnia, reduced weight gain. Caution recommended; consider delaying breastfeeding until 1-2 hours after dose.
Increased plasma volume and decreased plasma protein binding may require dose adjustments. However, no established guidelines; use lowest effective dose and shortest duration.
Pregnancy reduces amphetamine plasma concentrations by 15-50% during second/third trimesters due to increased clearance. Dose may need upward titration to maintain clinical effect, with careful monitoring for adverse effects.
ARESTOCAINE HYDROCHLORIDE (presumed anesthetic) is not a recognized drug; likely a misspelling of articaine or similar. If referring to articaine, clinical pearls: 1) Onset within 1-3 minutes, duration 1-3 hours; 2) Metabolized by plasma esterases, caution in pseudocholinesterase deficiency; 3) Maximum dose 7 mg/kg (adults) to avoid CNS/cardiac toxicity; 4) Contains sulfites, avoid in allergic patients.
Adderall 15 mg (amphetamine/dextroamphetamine) is an immediate-release formulation; onset 30-60 min, duration 4-6 hours. Avoid afternoon doses to prevent insomnia. Monitor for hypertension, tachycardia, and growth suppression in children. Consider drug holidays to assess need and reduce tolerance. Do not use with MAOIs or within 14 days of MAOI therapy. Risk of abuse and dependence; screen for substance use history. Use with caution in patients with pre-existing cardiovascular disease or psychiatric disorders.
Avoid chewing or biting lips/cheeks while numb to prevent injury.,Report any signs of allergic reaction (rash, swelling, difficulty breathing) immediately.,Do not consume hot foods or beverages until sensation returns.,Inform dentist of all medications, especially MAOIs or anticoagulants.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Take the first dose in the morning; if prescribed a second dose, take it by early afternoon to avoid sleep problems.,Swallow tablet whole; do not crush or chew.,Avoid alcohol and caffeine; may increase side effects like nervousness and rapid heartbeat.,Report chest pain, palpitations, shortness of breath, or fainting immediately.,Inform your doctor of all medications, including over-the-counter and herbal products, especially antidepressants.,May cause weight loss; monitor growth in children.,Can impair ability to drive or operate machinery until you know how it affects you.,Store at room temperature away from moisture and heat.,Do not abruptly stop; taper under medical supervision to avoid withdrawal.
