Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
BRIAN CARE is a nootropic agent that enhances cognitive function by modulating cholinergic and glutamatergic neurotransmission, increasing cerebral blood flow, and promoting neuroplasticity.
Adderall 12.5 is a combination of dextroamphetamine and amphetamine. It increases the levels of dopamine and norepinephrine in the central nervous system by inhibiting their reuptake and promoting their release from presynaptic neurons.
Improvement of cognitive function in patients with Alzheimer's disease,Treatment of mild cognitive impairment,Off-label: Attention deficit hyperactivity disorder,Off-label: Traumatic brain injury recovery
Attention deficit hyperactivity disorder (ADHD),Narcolepsy (off-label)
Administer 10 mg orally once daily.
5-60 mg orally once or twice daily; immediate-release: initial 5 mg once or twice daily, increase by 5 mg weekly; extended-release: initial 20 mg once daily in the morning, increase by 10 mg weekly.
Terminal elimination half-life is 12-15 hours in adults with normal renal function; prolonged to 24-30 hours in moderate renal impairment (Cr Cl 30-50 m L/min).
The terminal elimination half-life of d-amphetamine is approximately 10–13 hours in adults (range 9–14 h) and 6–8 hours in children. Clinical context: Typically allows twice-daily dosing; extended-release formulations provide 8–12 hours of effect.
Primarily metabolized by CYP3A4 and CYP2D6; undergoes glucuronidation and sulfation; renal excretion of metabolites.
Amphetamine and dextroamphetamine are extensively metabolized in the liver via CYP2D6 and other pathways. The primary metabolites are 4-hydroxyamphetamine and 4-hydroxynorephedrine.
Primarily renal excretion (70-80% as unchanged drug), with 15-20% fecal elimination via biliary excretion; less than 5% metabolized.
Approximately 30% of the dose is excreted unchanged in urine; the remainder is metabolized primarily via deamination and oxidation. Renal elimination of unchanged amphetamine is p H-dependent: acidic urine increases elimination, alkaline urine decreases it. Fecal excretion accounts for <5%.
Approximately 85% bound, primarily to albumin.
Approximately 15–20% bound to plasma proteins, primarily albumin.
0.6-0.8 L/kg, indicating moderate tissue distribution; Vd increases in obesity and decreases in dehydration.
Mean volume of distribution is 3.5–4.6 L/kg, indicating extensive tissue distribution. Clinical meaning: Large Vd reflects sequestration in tissues (including brain), contributing to prolonged presence.
Oral: 60-70% (due to first-pass metabolism); Intramuscular: 90-100%.
Oral bioavailability is highly variable, ranging from 75–100% for immediate-release tablets; food does not significantly affect overall absorption but may delay time to peak concentration. Extended-release capsules have bioavailability approximately 96% relative to immediate-release.
e GFR >=60 m L/min: no adjustment; e GFR 30-59: reduce to 5 mg once daily; e GFR <30: not recommended.
GFR 15-29 m L/min: reduce dose to 50% of usual; GFR <15 m L/min: use 50% of usual dose; hemodialysis: not removed, avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: reduce to 5 mg once daily; Child-Pugh C: avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: use 50% of usual dose; Child-Pugh C: avoid use.
Not approved for use in pediatric patients under 18 years.
Immediate-release: 3-5 years: initial 2.5 mg once daily, increase by 2.5 mg weekly up to 40 mg/day; 6+ years: initial 5 mg once or twice daily, increase by 5 mg weekly up to 40 mg/day. Extended-release: 6-12 years: initial 10 mg once daily, increase by 10 mg weekly up to 30 mg/day; 13-17 years: initial 10 mg once daily, increase by 10 mg weekly up to 40 mg/day.
Start at 5 mg once daily; titrate based on tolerance and renal function.
Start at lowest dose (5 mg immediate-release or 10 mg extended-release) and titrate slowly due to increased risk of adverse cardiovascular and CNS effects; monitor for hypertension, tachycardia, and agitation.
None
Adderall has a high potential for abuse and dependence. Prolonged use may lead to drug dependence. Misuse may cause sudden death or serious cardiovascular adverse events.
Risk of hepatotoxicity with prolonged use,May exacerbate anxiety or agitation in susceptible patients,Use caution in patients with renal impairment,Drug interactions with anticoagulants and anticholinergics
Risk of abuse and dependence,Serious cardiovascular events including sudden death, stroke, and myocardial infarction,Blood pressure and heart rate increases,Psychiatric adverse events including exacerbation of pre-existing psychosis, mania, or aggression,Seizures in patients with seizure disorders,Visual disturbances,Growth suppression in children,Peripheral vasculopathy including Raynaud's phenomenon,Serotonin syndrome risk when used with serotonergic drugs
Hypersensitivity to any component,Severe hepatic impairment,Pregnancy and lactation

No known food interactions for this fictional drug.
Avoid acidic foods and beverages (e.g., citrus fruits, soda) within 1 hour of administration as they may decrease absorption. High-fat meals may delay absorption of extended-release formulations. Avoid caffeine and other stimulants. Grapefruit juice may increase amphetamine levels.
First trimester: Not associated with major malformations based on limited data. Second and third trimesters: No known fetal toxicity. Animal studies have not shown teratogenic effects. However, due to lack of comprehensive human studies, caution is advised.
First trimester: Increased risk of congenital malformations, particularly cardiovascular defects (e.g., septal defects) and oral clefts based on amphetamine exposure. Second and third trimesters: risk of preterm delivery, low birth weight, and neonatal withdrawal syndrome (irritability, feeding difficulties, respiratory distress). Premature delivery and growth restriction have been reported.
Breastfeeding: Limited data suggest the drug may be excreted in human breast milk in small amounts. M/P ratio not established. Potential for adverse effects in nursing infants is low, but due to insufficient evidence, avoid use unless clearly needed.
Contraindicated due to potential for infant toxicity. M/P ratio not established; amphetamine is excreted into breast milk in small amounts but may accumulate in breastfeeding infants. Adverse effects include irritability, poor feeding, and decreased weight gain.
No pharmacokinetic data indicate significant changes during pregnancy. Dose adjustment not required based on current knowledge.
Pharmacokinetics altered: increased hepatic metabolism and renal clearance in pregnancy may reduce amphetamine exposure; however, safety data do not support dose adjustment. Use lowest effective dose only if necessary; consider alternative non-amphetamine therapies.
