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 relaxes bronchial smooth muscle by inhibiting phosphodiesterase, increasing intracellular cAMP, and blocking adenosine receptors.
2.5 mg (0.5 mL of 0.5% solution) via nebulization three to four times daily, as needed.
Oral: 300-600 mg every 12 hours; extended-release tablets. Titrate to serum theophylline concentration of 5-15 mcg/mL.

Terminal elimination half-life is 3–4 hours; prolonged in hepatic impairment (up to 8 hours).
Terminal elimination half-life: 3–12 hours in healthy adults; prolonged in hepatic impairment (up to 30 hours), congestive heart failure, and in neonates; also prolonged in elderly and patients with fever or viral illness. Half-life is shorter in smokers (4–5 hours).
Primarily renal excretion as sulfate conjugates; unchanged drug accounts for <10% of excretion. Biliary/fecal excretion is minimal (<2%).
Renal excretion of unchanged drug: approximately 10%; hepatic metabolism accounts for >90% of elimination; metabolites are excreted renally. Less than 5% eliminated in feces.
