Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bronchodilator via beta-2 adrenergic receptor agonism, increasing intracellular cAMP, leading to smooth muscle relaxation in the airways.
Theophylline is a methylxanthine that inhibits phosphodiesterase, increasing intracellular cAMP levels, leading to bronchodilation. It also acts as an adenosine receptor antagonist and may enhance diaphragmatic contractility.
2.5 mg (0.5 mL of 0.5% solution) via nebulization three to four times daily, as needed.
Theophylline 200 mg orally every 6 hours (extended-release) or as directed by serum theophylline concentrations. Usual adult target: 400-600 mg/day.

Terminal elimination half-life is 3–4 hours; prolonged in hepatic impairment (up to 8 hours).
Terminal elimination half-life: ~8 hours (range 3–12 hours) in adults; prolonged in hepatic impairment, heart failure, COPD, and neonates. Significantly shorter in smokers (4–6 hours).
Primarily renal excretion as sulfate conjugates; unchanged drug accounts for <10% of excretion. Biliary/fecal excretion is minimal (<2%).
Renal: ~10% unchanged; Hepatic metabolism (CYP1A2, CYP3A4) accounts for ~90% of elimination; metabolites (caffeine, 3-methylxanthine, 1-methyluric acid) excreted renally. Fecal excretion negligible.
