Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Theophylline is a xanthine derivative that acts as a bronchodilator by relaxing bronchial smooth muscle. Its mechanism may involve inhibition of phosphodiesterase, increasing cyclic AMP, and adenosine receptor antagonism.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
Treatment of symptoms and reversible airflow obstruction associated with chronic asthma and other chronic lung diseases, such as emphysema and chronic bronchitis.
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
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 elimination half-life: 3.5-4.5 hours. This short half-life supports twice-daily dosing in asthma management, with trough levels remaining above therapeutic threshold.
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.
Primarily metabolized in the liver by cytochrome P450 enzymes, including CYP1A2, CYP2E1, and CYP3A4. Metabolism is saturable at high concentrations.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
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%.
Approximately 70% bound to plasma proteins, primarily albumin.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
Volume of distribution: 0.3-0.5 L/kg. This moderate Vd indicates distribution into total body water and some tissue binding, but limited by protein 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 bioavailability: Approximately 50% due to first-pass metabolism. Inhalation bioavailability: Variable, with 10-20% reaching systemic circulation; remainder swallowed and undergoes first-pass metabolism.
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.
No adjustment required as drug is primarily hepatically metabolized.
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
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: not recommended.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use
Children 4-11 years: 1 inhalation (35 mcg) twice daily; children 12-17 years: same as adult.
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
No specific dose adjustment; initiate at lower end of dosing range due to potential comorbidities.
Initiate at 2.5 mg orally once or twice daily; titrate slowly; monitor for cardiovascular effects, insomnia, and weight loss
None.
Amphetamines have a high potential for abuse and dependence. Misuse may cause sudden death or serious cardiovascular events.
Concurrent illness (especially with fever), smoking cessation, drug interactions, and hepatic or cardiac impairment can significantly alter theophylline clearance. Serum levels must be monitored due to narrow therapeutic index. Use with caution in patients with peptic ulcer, seizure disorders, or hyperthyroidism.
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
Hypersensitivity to theophylline or any component of the formulation.
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
High-fat meals may delay absorption. Charcoal-broiled foods and high-protein diets can increase clearance. Avoid concurrent consumption of large amounts of caffeine.
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.
FDA Pregnancy Category C. First trimester: No human studies; animal studies show fetal loss, delayed ossification. Second/third trimester: Risk of neonatal hypoglycemia if used near term due to beta-agonist effects; avoid for tocolysis.
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 2.5. Use caution; may cause tremors or tachycardia in infant. Consider risk-benefit.
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.
Pregnancy may reduce plasma concentrations due to increased clearance; consider dose adjustment based on clinical response. Monitor for hypokalemia.
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.
AEROLATE JR (theophylline) is a bronchodilator used for asthma and COPD. Due to narrow therapeutic index, monitor serum levels (target 5-15 mcg/m L). Caffeine and smoking affect metabolism; smoking cessation may require dose reduction. Avoid in seizure disorders or peptic ulcer.
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.
