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 relaxes bronchial smooth muscle by inhibiting phosphodiesterase, increasing intracellular cAMP, and antagonizing adenosine receptors.
2 inhalations (200 mcg per inhalation) every 4 hours as needed for bronchospasm. Maximum 12 inhalations in 24 hours.
100 mg orally every 6 hours; adjust based on serum theophylline concentrations and clinical response (target 5-15 mcg/mL).

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 approximately 8-12 hours in healthy adults. In smokers, half-life is reduced by 50%; in patients with hepatic cirrhosis or heart failure, half-life is prolonged to 24-36 hours.
Renal: 40-70% unchanged; fecal: minor (biliary) <5%
Renal excretion accounts for approximately 10% of the administered dose as unchanged drug. The remainder is hepatically metabolized, with metabolites excreted renally. Biliary/fecal elimination is negligible (<5%).
