Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Theophylline is a xanthine derivative that acts as a competitive nonselective phosphodiesterase inhibitor, increasing intracellular cyclic AMP levels, and as an antagonist at adenosine receptors (A1 and A2 subtypes), leading to bronchodilation, anti-inflammatory effects, and stimulation of respiratory drive.
2 inhalations (200 mcg per inhalation) every 4 hours as needed for bronchospasm. Maximum 12 inhalations in 24 hours.
Oral: 200-400 mg every 6 hours (maximum 1600 mg/day) as sustained-release tablets or liquid. Inhalation: Not applicable.

Terminal elimination half-life: 3-6 hours; clinical context: shorter half-life in children, prolonged in hepatic impairment; requires frequent dosing
Terminal elimination half-life is 3–5 hours in adults (nonsmokers), but prolonged to 6–8 hours in neonates, elderly, and patients with hepatic cirrhosis or heart failure. Smoking (tobacco or marijuana) reduces half-life to 1–2 hours due to enzyme induction.
Renal: 40-70% unchanged; fecal: minor (biliary) <5%
Renal excretion of unchanged drug accounts for approximately 10% of elimination; the remainder is hepatically metabolized, with 80% excreted in urine as metabolites (1-methyluric acid and 3-methylxanthine) and less than 10% in feces.
