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 causes bronchodilation by inhibiting phosphodiesterase, increasing cAMP levels, and antagonizing adenosine receptors.
2.5 mg (0.5 mL of 0.5% solution) via nebulization three to four times daily, as needed.
Theophylline (THEOCLEAR L.A.-260) 260 mg orally every 12 hours. Adjust dose based on serum theophylline concentrations to achieve 5-15 mcg/mL.

Terminal elimination half-life is 3–4 hours; prolonged in hepatic impairment (up to 8 hours).
Terminal elimination half-life is approximately 6-12 hours in adults (range 3-12 hours, prolonged in congestive heart failure, liver disease, and with certain drugs). In neonates, half-life is prolonged (24-36 hours).
Primarily renal excretion as sulfate conjugates; unchanged drug accounts for <10% of excretion. Biliary/fecal excretion is minimal (<2%).
Renal elimination of unchanged drug (10%) and hepatic metabolism (90%). Metabolism is primarily via CYP1A2 and CYP3A4, with metabolites excreted in urine (about 80% of the dose) and feces (about 20%).
