ADDERALL 30 vs AEROLATE SR
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
AEROLATE SR is a sustained-release formulation of theophylline, a methylxanthine bronchodilator. It acts by inhibiting phosphodiesterase (PDE) isoenzymes, leading to increased intracellular cyclic AMP (c AMP) levels. This results in relaxation of bronchial smooth muscle and suppression of the response of airways to stimuli. Theophylline also has anti-inflammatory effects, including inhibition of late-phase allergen-induced responses and reduction of eosinophil infiltration.
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
Treatment of symptoms and reversible airway obstruction associated with chronic asthma,Chronic obstructive pulmonary disease (COPD),Apnea of prematurity (off-label)
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
400-800 mcg inhaled twice daily. For acute bronchospasm, 200-400 mcg as needed.
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.
Terminal elimination half-life 12 hours (range 10–15 h) in adults; prolonged in hepatic impairment (up to 24 h) and elderly.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Primarily hepatic via cytochrome P450 enzymes (CYP1A2, CYP2E1, and CYP3A4). Theophylline is metabolized to 1,3-dimethyluric acid, 1-methyluric acid, and 3-methylxanthine.
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%.
Renal: 60% as unchanged drug; biliary/fecal: 30% as metabolites; 10% as unchanged in feces.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
55–65% bound to plasma proteins, primarily albumin.
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.
0.4–0.6 L/kg, indicating distribution into total body water.
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.
Oral: 90–100% for sustained-release formulation; food decreases rate but not extent (AUC unchanged).
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 dose adjustment required for renal impairment.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use
Use with caution in severe hepatic impairment (Child-Pugh class C); consider dose reduction by 50%.
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
Children 6-12 years: 200-400 mcg inhaled twice daily. Children over 12 years: same as adult dose.
Initiate at 2.5 mg orally once or twice daily; titrate slowly; monitor for cardiovascular effects, insomnia, and weight loss
Start at lower end of dosing range (400 mcg twice daily) and titrate to response; monitor for systemic effects.
Amphetamines have a high potential for abuse and dependence. Misuse may cause sudden death or serious cardiovascular events.
No FDA black box warning exists for this drug.
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
Theophylline has a narrow therapeutic index; serum levels must be monitored to avoid toxicity. Toxicity can include seizures, cardiac arrhythmias, and death. Caution in patients with heart failure, hepatic impairment, or those over 55 years. Risk of toxicity increased by concurrent medications such as cimetidine, fluoroquinolones, and macrolides.
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
Hypersensitivity to theophylline or any component of the formulation; active seizure disorder; untreated cardiac arrhythmias; severe hypertension; hyperthyroidism; peptic ulcer disease; caution with concurrent use of ephedrine or other sympathomimetics.
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.
High-fat meals may delay absorption. Avoid charcoal-grilled foods and large amounts of caffeine. Grapefruit juice may increase theophylline levels; limit intake.
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.
Pregnancy Category C. In first trimester: insufficient human data; animal studies show adverse effects at high doses. Second and third trimesters: may cause fetal tachycardia, hypoglycemia, and reduced uterine contractility; avoid use near term due to potential for neonatal bradycardia and hypoglycemia.
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.
Salbutamol is excreted into breast milk in minimal amounts; estimated infant dose <2% of maternal weight-adjusted dose. No known adverse effects in nursing infants. M/P ratio not established. Use with caution.
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.
No dose adjustment required for inhaled salbutamol. Increased clearance in late pregnancy may necessitate higher doses for systemic effects; monitor clinical response and adjust accordingly.
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.
AEROLATE SR contains theophylline; narrow therapeutic index (10-20 mcg/m L). Monitor serum levels, especially with CYP1A2 inhibitors (e.g., ciprofloxacin, fluvoxamine) or inducers (e.g., carbamazepine, phenytoin). SR formulation avoids peak-trough fluctuations; do not crush or chew. Caution in heart failure, hepatic impairment, and elderly.
