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 10 contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote the release of dopamine and norepinephrine from presynaptic neurons, inhibit their reuptake, and inhibit monoamine oxidase activity, thereby increasing extracellular levels of these neurotransmitters in the central nervous system.
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.
10 mg orally once daily in the morning, with or without food; may increase by 5-10 mg weekly based on tolerability and response; usual effective dose 10-40 mg/day divided into 2-3 doses; maximum 60 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: dextroamphetamine 9-11 hours, levoamphetamine 11-14 hours (Adderall is a mixed salt). In adults, mean half-life ~10 hours; in children, slightly shorter (6-8 hours). Clinical context: steady-state reached in 2-3 days; dosing interval typically 4-6 hours for immediate-release.
Primarily metabolized in the liver by cytochrome P450 enzymes, including CYP1A2, CYP2E1, and CYP3A4. Metabolism is saturable at high concentrations.
Amphetamine is metabolized primarily in the liver via cytochrome P450 enzymes, including CYP2D6, and undergoes deamination and oxidation to form inactive metabolites including 4-hydroxyamphetamine and norephedrine.
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
Renal: 70-80% (30-40% as unchanged amphetamine; remainder as deaminated and hydroxylated metabolites). Fecal: minimal (<5%). Biliary: negligible. Urinary p H affects excretion: acidic urine increases elimination, alkaline urine decreases.
Approximately 70% bound to plasma proteins, primarily albumin.
Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.
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.
Apparent Vd: 3.0-4.0 L/kg (for total amphetamine). High Vd indicates extensive tissue distribution, including brain. Clinical meaning: loading dose may be needed for rapid effect; distribution half-life ~1 hour.
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: 100% (well-absorbed; first-pass metabolism minimal). Food delays absorption but does not affect extent. Extended-release: bioavailability similar to immediate-release with modified release profile.
No adjustment required as drug is primarily hepatically metabolized.
e GFR 15-29 m L/min: reduce dose by 50% and monitor for toxicity; e GFR <15 m L/min or dialysis: avoid use due to risk of accumulation; consider alternative therapy.
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 due to decreased clearance and increased risk of toxicity.
Children 4-11 years: 1 inhalation (35 mcg) twice daily; children 12-17 years: same as adult.
Children 3-5 years: 2.5 mg orally once daily; may increase by 2.5 mg weekly; usual range 2.5-20 mg/day divided 1-2 times. Children 6 years and older: initial 5 mg once daily; may increase by 5 mg weekly; usual range 5-40 mg/day divided 1-3 times; maximum 40 mg/day.
No specific dose adjustment; initiate at lower end of dosing range due to potential comorbidities.
Initiate at 2.5-5 mg orally once daily; titrate slowly in increments of 2.5-5 mg weekly; monitor for cardiovascular effects, insomnia, and weight loss; maximum 40 mg/day.
None.
Potential for abuse and dependence. Amphetamines have a high potential for abuse, which may lead to dependence and serious cardiovascular adverse events. Misuse may cause sudden death and 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.
Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities or other serious heart problems.,Blood pressure and heart rate increase; caution in hypertension and other cardiovascular conditions.,Psychiatric adverse events including exacerbation of psychosis, mania, and aggression.,Long-term suppression of growth in pediatric patients.,Peripheral vasculopathy including Raynaud's phenomenon.,Seizures: may lower seizure threshold.,Serotonin syndrome risk when co-administered with serotonergic drugs.
Hypersensitivity to theophylline or any component of the formulation.
Advanced arteriosclerosis,Symptomatic cardiovascular disease,Moderate to severe hypertension,Hyperthyroidism,Known hypersensitivity or idiosyncrasy to sympathomimetic amines,Glaucoma,Agitated states,History of drug abuse,During or within 14 days following the administration of monoamine oxidase inhibitors (hypertensive crises may occur)
High-fat meals may delay absorption. Charcoal-broiled foods and high-protein diets can increase clearance. Avoid concurrent consumption of large amounts of caffeine.
High-fat meals can delay absorption; avoid acidic foods (e.g., citrus, cola) within 1 hour of dosing as they decrease absorption. Avoid caffeine; may increase stimulant 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: potential increased risk of congenital malformations (e.g., gastroschisis, oral clefts) based on limited human data. Second and third trimesters: risk of fetal growth restriction, preterm delivery, and neonatal withdrawal symptoms (irritability, poor feeding).
Excreted in breast milk; M/P ratio 2.5. Use caution; may cause tremors or tachycardia in infant. Consider risk-benefit.
Excreted into breast milk; relative infant dose estimated at 2-4% of maternal weight-adjusted dose. M/P ratio not well established. Manufacturer recommends caution; potential for infant agitation, insomnia, and growth suppression.
Pregnancy may reduce plasma concentrations due to increased clearance; consider dose adjustment based on clinical response. Monitor for hypokalemia.
Increased plasma volume and enhanced hepatic metabolism may reduce amphetamine levels; dose adjustments should be individualized based on clinical response, but controlled studies lacking. Avoid abrupt discontinuation due to risk of withdrawal symptoms in mother and neonate.
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.
Adderall 10 mg contains immediate-release amphetamine salts. Onset of action is 30-60 minutes, duration 4-6 hours. Monitor for appetite suppression, insomnia, and cardiovascular effects. Avoid in patients with structural cardiac abnormalities or history of substance abuse. Use with caution in hypertension or hyperthyroidism. Drug holidays may reduce tolerance.
