Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Epinephrine, the active ingredient, is a direct-acting sympathomimetic amine that stimulates alpha- and beta-adrenergic receptors. Beta-2 receptor activation in bronchial smooth muscle causes bronchodilation. Alpha receptor activation causes vasoconstriction, reducing mucosal edema.
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.

No specific dose adjustment guidelines available. Use with caution in severe hepatic impairment (Child-Pugh class C) due to potential for increased systemic exposure.
Child-Pugh A: no adjustment. Child-Pugh B: reduce dose by 50%. Child-Pugh C: avoid use.
Not recommended for children under 12 years of age. For children 12 years and older, same as adult dosing: 2 inhalations every 4 hours as needed, max 12 inhalations per day.
Children 2-11 years: 1 inhalation (100 mcg) twice daily via metered-dose inhaler. Children 12 years and older: same as adult.
No specific dose adjustment required. Use with caution due to increased risk of tachycardia, hypertension, and CNS stimulation. Consider starting at lower doses if tolerated.
No specific dose adjustment but monitor for increased systemic effects; start at lowest effective dose.
None
No FDA black box warning.
Do not use if solution is brown or cloudy,Do not use if more than the number of inhalations prescribed per 24 hours are needed,May cause increased blood pressure, tachycardia, and other cardiovascular effects,May cause nervousness, tremor, or insomnia,Do not exceed recommended dosage
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.
Hypersensitivity to epinephrine or any component,Cardiac arrhythmias associated with tachycardia or myocardial insufficiency,Concurrent use with monoamine oxidase inhibitors (MAOIs) or within 2 weeks of discontinuing MAOIs,Narrow-angle glaucoma,Labor and delivery (may delay second stage),Hypertension, hyperthyroidism, or diabetes (relative contraindications)
Hypersensitivity to theophylline or any component; pre-existing cardiac arrhythmias (e.g., ventricular tachycardia); recent myocardial infarction; uncontrolled seizure disorders.
Avoid caffeine-containing foods and beverages (coffee, tea, cola, chocolate) as they may increase the risk of cardiovascular side effects such as palpitations and tachycardia. No other significant food interactions are known.
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.
FDA Pregnancy Category C. First trimester: Inadequate human data; animal studies show no teratogenicity at clinically relevant doses but fetal toxicity at high doses. Second/third trimesters: Risk of fetal tachycardia, hypoglycemia, and transient neonatal hyperexcitability due to beta-agonist effects. Avoid use near term due to potential for uterine relaxation and delayed labor.
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.
Epinephrine (active ingredient) is excreted in breast milk in minimal amounts. M/P ratio not established. Short-acting beta-agonist use is considered compatible with breastfeeding; however, monitor infant for irritability and tachycardia.
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.
No specific dose adjustments recommended; however, use lowest effective dose due to increased clearance and larger volume of distribution. Closely monitor for maternal and fetal effects; consider alternative agents if frequent dosing required.
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.
BRONKAID MIST contains epinephrine, a non-selective adrenergic agonist. Inhaled epinephrine is rapidly absorbed and can cause tachycardia, hypertension, and cardiac arrhythmias. It is contraindicated in patients with coronary artery disease, hypertension, or hyperthyroidism. Use with caution in patients with diabetes, as it may increase blood glucose. Note that BRONKAID MIST delivers a fixed dose; repeated use more than every 3-4 hours or exceeding 12 inhalations in 24 hours may indicate inadequate control and need for medical evaluation.
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.
Do not use if you have heart disease, high blood pressure, diabetes, or thyroid disease without consulting a doctor.,Seek emergency medical help if symptoms worsen or do not improve after 20 minutes.,Do not exceed 12 inhalations in 24 hours or use more often than every 4 hours.,If you miss a dose, take it as soon as you remember, but do not double up.,Keep away from children; accidental ingestion can be fatal.,Store at room temperature away from heat and open flame (pressurized container).,Do not puncture or incinerate the canister, even when empty.
Take this medication exactly as prescribed; do not crush or chew extended-release tablets.,Avoid consuming large amounts of caffeine (coffee, tea, chocolate) as it may increase side effects like jitteriness and insomnia.,Inform your doctor if you experience nausea, vomiting, rapid heartbeat, or seizures.,Do not stop taking this medication abruptly; taper under medical supervision.,Keep all appointments for blood tests to monitor theophylline levels.,Avoid smoking or using nicotine products, as they affect how the medication works.,Carry a list of all medications you take, as many can interact with theophylline.
