Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
AEROLATE III (theophylline) is a bronchodilator that inhibits phosphodiesterase, increasing intracellular c AMP levels, leading to relaxation of bronchial smooth muscle and suppression of airway inflammation.
Adderall 15 is a combination of amphetamine and dextroamphetamine, which increase synaptic concentrations of norepinephrine and dopamine by inhibiting their reuptake and promoting their release from presynaptic terminals.
Treatment and prophylaxis of bronchospasm associated with asthma, chronic bronchitis, and emphysema,Off-label: Apnea of prematurity (oral/IV theophylline)
Attention deficit hyperactivity disorder (ADHD),Narcolepsy
Inhalation: 2 inhalations (200 mcg) twice daily, max 4 inhalations (400 mcg) per day. Oral: 4 mg twice daily, max 8 mg per day.
10-20 mg orally once daily in the morning; may increase by 5-10 mg weekly; maximum 40 mg/day.
Terminal half-life 12-15 hours; clinically allows twice-daily dosing
Mean terminal half-life: d-amphetamine 10 h, l-amphetamine 13 h (range 9-14 h); for ADDERALL 15 (3:1 mix), effective half-life ~11 h; clinical context: dosing interval typically QD-BID.
Primarily hepatic via cytochrome P450 1A2 (CYP1A2); also CYP2E1 and CYP3A4; exhibits nonlinear pharmacokinetics.
Amphetamine is metabolized primarily by hepatic CYP2D6 and to a lesser extent by CYP2C19 and CYP2C9, with some minor pathways involving dopamine beta-hydroxylase.
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other
Primarily renal (90% as unchanged drug and metabolites; ~30% unchanged, 40% as 4-hydroxyamphetamine and conjugates, 20% as other metabolites); minimal biliary/fecal elimination (<3%).
92-96%, primarily to albumin and alpha-1-acid glycoprotein
~16-20%; primarily binds to albumin, with minor binding to alpha-1-acid glycoprotein.
Vd 1.5-2.0 L/kg, indicating extensive tissue distribution
Vd: 3.0-4.5 L/kg (range 2.6-5.6); indicates extensive tissue distribution, including brain, with accumulation in kidneys and liver.
Oral: 40-50%; Inhalation: 20-30%
Oral: ~76% (range 64-95%) for mixed amphetamine salts; bioavailability reduced by acidic gastric p H and increased with food (Tmax delayed but AUC unchanged).
No adjustment needed for GFR >30 m L/min. For GFR 10-30 m L/min: use 50% of usual dose. For GFR <10 m L/min: avoid use.
GFR 15-29 m L/min: reduce dose by 50%; GFR <15 m L/min: contraindicated.
Child-Pugh A: no adjustment. Child-Pugh B: reduce dose by 50%. Child-Pugh C: avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated.
Children 2-11 years: 1 inhalation (100 mcg) twice daily via metered-dose inhaler. Children 12 years and older: same as adult.
Weight-based: <50 kg: 2.5-5 mg once daily; 50-100 kg: 5-10 mg once daily; >100 kg: adult dosing.
No specific dose adjustment but monitor for increased systemic effects; start at lowest effective dose.
Start at 2.5-5 mg once daily; increase slowly due to increased sensitivity and cardiovascular risk.
No FDA black box warning.
WARNING: ABUSE AND DEPENDENCE. CNS stimulants, including Adderall, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence throughout therapy.
Monitor serum theophylline concentrations due to narrow therapeutic index; risk of toxicity at levels >20 mcg/m L; use caution in patients with cardiac disease, hepatic impairment, or seizures; may exacerbate arrhythmias; drug interactions with cimetidine, fluoroquinolones, macrolides, allopurinol, oral contraceptives, smoking, and others.
Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities or other serious heart problems,Blood pressure and heart rate increases,Psychiatric adverse events (exacerbation of pre-existing psychosis, manic episodes, aggressive behavior),Seizures (may lower seizure threshold),Peripheral vasculopathy including Raynaud's phenomenon,Serotonin syndrome risk, especially with concomitant serotonergic drugs,Long-term growth suppression in children
Hypersensitivity to theophylline or any component; pre-existing cardiac arrhythmias (e.g., ventricular tachycardia); recent myocardial infarction; uncontrolled seizure disorders.
Hypersensitivity to amphetamine or other components,Concurrent use or within 14 days of MAOIs (risk of hypertensive crisis),Glaucoma,Hyperthyroidism,Agitated states,History of drug abuse,Cardiovascular disease (symptomatic, moderate to severe hypertension, advanced arteriosclerosis, structural cardiac abnormalities)
Avoid significant intake of caffeine-containing foods/beverages (coffee, tea, cola, chocolate) as they may increase CNS stimulation and risk of toxicity. Charcoal-broiled foods and a high-protein diet may increase clearance. Maintain consistent dietary patterns; avoid extremes of protein/carbohydrate intake.
Avoid high-fat meals close to dosing as they may delay absorption. Acidic foods (e.g., citrus, cola, vitamin C) can decrease absorption; take with non-acidic fluids. Avoid alcohol and caffeine-containing products.
AEROLATE III (theophylline) is FDA Pregnancy Category C. First trimester: No well-controlled studies; potential risk cannot be ruled out. Second/third trimesters: Increased fetal heart rate, jitteriness, and risk of neonatal apnea with high maternal serum concentrations (>15 mcg/m L). Avoid near term due to prolonged neonatal half-life.
First trimester: Possible increased risk of congenital malformations (cardiac, oral clefts) based on limited human data; animal studies show dose-dependent teratogenicity. Second/third trimesters: Risk of fetal growth restriction, preterm delivery, neonatal withdrawal (irritability, feeding problems), and persistent pulmonary hypertension.
Theophylline is excreted into breast milk with an M/P ratio of approximately 0.7. Infant serum levels can reach 50% of maternal levels; risk of irritability and sleep disturbances in nursing infants. Use with caution and monitor infant for signs of toxicity.
Present in breast milk; M/P ratio approximately 2.5-7.5. Potential for infant stimulation, insomnia, reduced weight gain. Caution recommended; consider delaying breastfeeding until 1-2 hours after dose.
Pregnancy may increase theophylline clearance due to enhanced hepatic metabolism and increased renal blood flow. Dose adjustments are often required: monitor serum levels regularly and adjust dose to maintain therapeutic levels. Typically, dose may need to be increased by 20-50% in second and third trimesters.
Pregnancy reduces amphetamine plasma concentrations by 15-50% during second/third trimesters due to increased clearance. Dose may need upward titration to maintain clinical effect, with careful monitoring for adverse effects.
AEROLATE III (theophylline) is a bronchodilator with a narrow therapeutic index; monitor serum levels (target 10-20 mcg/m L). Caffeine and smoking increase clearance; hepatic impairment, heart failure, and certain drugs (e.g., cimetidine, fluoroquinolones) decrease clearance. Avoid use in patients with active peptic ulcer or seizure disorders. Titrate dose slowly to minimize nausea, vomiting, and arrhythmias.
Adderall 15 mg (amphetamine/dextroamphetamine) is an immediate-release formulation; onset 30-60 min, duration 4-6 hours. Avoid afternoon doses to prevent insomnia. Monitor for hypertension, tachycardia, and growth suppression in children. Consider drug holidays to assess need and reduce tolerance. Do not use with MAOIs or within 14 days of MAOI therapy. Risk of abuse and dependence; screen for substance use history. Use with caution in patients with pre-existing cardiovascular disease or psychiatric disorders.
