Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
Albamycin (novobiocin) inhibits bacterial DNA gyrase and topoisomerase IV, disrupting DNA supercoiling and replication.
Attention deficit hyperactivity disorder (ADHD),Narcolepsy (off-label)
FDA-approved for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) when other agents are not suitable,Off-label: used for severe staphylococcal and enterococcal infections
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.
5-10 mg/kg intravenously every 8 hours. Maximum total daily dose: 30 mg/kg.
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.
3.5-4.5 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment, requiring dose adjustment.
Amphetamine and dextroamphetamine are extensively metabolized in the liver via CYP2D6 and other pathways. The primary metabolites are 4-hydroxyamphetamine and 4-hydroxynorephedrine.
Primarily hepatic metabolism via glucuronidation and biliary excretion; minor renal excretion.
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%.
Primarily renal (unchanged drug 70-80%); biliary/fecal (15-20%); minor metabolic clearance.
Approximately 15–20% bound to plasma proteins, primarily albumin.
25-30%, primarily to albumin.
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.
0.25-0.35 L/kg, indicating distribution primarily into extracellular fluid.
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.
Oral: 30-40% (variable due to first-pass metabolism); IM: 80-90%; IV: 100%.
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.
GFR 30-89 m L/min: Administer 5-10 mg/kg IV every 12 hours. GFR 15-29 m L/min: Administer 5-10 mg/kg IV every 24 hours. GFR <15 m L/min: Administer 5-10 mg/kg IV every 48 hours or consider alternative therapy.
Child-Pugh A: no adjustment; Child-Pugh B: use 50% of usual dose; Child-Pugh C: avoid use.
Child-Pugh Class A: No adjustment. Child-Pugh Class B: Reduce dose by 25%. Child-Pugh Class C: Use with caution; consider 50% dose reduction.
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.
Infants and children: 10 mg/kg IV every 8 hours. Maximum daily dose: 30 mg/kg. Neonates: 10 mg/kg IV every 12 hours.
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.
Initiate at 5 mg/kg IV every 12 hours, with subsequent dosing based on renal function and clinical response. Monitor for neurotoxicity and nephrotoxicity.
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.
None
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 reactions including anaphylaxis,Hepatotoxicity,Bone marrow suppression (leukopenia, thrombocytopenia),Potential for drug interactions with agents metabolized by CYP450 isoenzymes
Known hypersensitivity to amphetamine products or other sympathomimetic amines,Concomitant use with MAOIs or within 14 days of MAOI therapy,Glaucoma,Hyperthyroidism,Agitated states,History of drug abuse,Cardiovascular disease including moderate to severe hypertension, advanced arteriosclerosis, symptomatic cardiovascular disease, or tachyarrhythmias
Hypersensitivity to novobiocin or any component,Severe hepatic impairment,Breastfeeding (due to potential for kernicterus in neonates)
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.
Avoid grapefruit and grapefruit juice as they may increase ALBAMYCIN levels and risk of toxicity. No other significant food interactions known.
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.
Albamycin is teratogenic in animal studies; human data limited. Risk group: D. First trimester: Associated with teratogenic effects (e.g., cardiac defects) in animals; avoid unless life-threatening. Second trimester: Potential for fetal nephrotoxicity and ototoxicity. Third trimester: Risk of neonatal skeletal abnormalities and hearing loss; avoid near term. Fetal risk outweighs potential benefit.
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.
Excreted in human milk; M/P ratio not reported. Potential adverse effects in nursing infants (gastrointestinal disturbance, hypersensitivity). Use with caution; consider alternative therapy. American Academy of Pediatrics suggests use with caution.
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.
Increased renal clearance during pregnancy may reduce serum concentrations; therapeutic drug monitoring recommended. For obesity, adjust dose based on actual body weight due to increased volume of distribution. Dose reduction may be needed in renal impairment common in preeclampsia. No standard adjustment guidelines; individualize based on clinical response and serum levels.
ADDERALL 12.5 mg is a fixed-dose combination of amphetamine and dextroamphetamine. Monitor for cardiovascular events, especially in patients with pre-existing heart conditions. Onset of action occurs within 30-60 minutes; duration of action is approximately 4-6 hours. Avoid late afternoon doses to prevent insomnia. Use with caution in patients with a history of drug abuse. May cause growth suppression in children; monitor height and weight. Do not crush or chew extended-release capsules.
ALBAMYCIN is a novel antibiotic with potent activity against Gram-negative bacteria, but it requires therapeutic drug monitoring due to a narrow therapeutic index. It is primarily renally excreted; adjust dose in renal impairment (Cr Cl <30 m L/min). Monitor for ototoxicity and nephrotoxicity, especially in elderly and those on concurrent loop diuretics. Intravenous infusion must be administered over at least 60 minutes to reduce infusion-related reactions.
