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 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.
2.5 mg (0.5 mL of 0.5% solution) via nebulization three to four times daily, as needed.
Oral: 200-400 mg every 6 hours (maximum 1600 mg/day) as sustained-release tablets or liquid. Inhalation: Not applicable.

Terminal elimination half-life is 3–4 hours; prolonged in hepatic impairment (up to 8 hours).
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.
Primarily renal excretion as sulfate conjugates; unchanged drug accounts for <10% of excretion. Biliary/fecal excretion is minimal (<2%).
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.
