Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline relaxes bronchial smooth muscle by inhibiting phosphodiesterase, increasing intracellular cAMP, and antagonizing adenosine receptors.
Inhibits phosphodiesterase, increasing cAMP levels, leading to bronchodilation and reduced airway inflammation.
100 mg orally every 6 hours; adjust based on serum theophylline concentrations and clinical response (target 5-15 mcg/mL).
Oral: 400-800 mg every 6-8 hours; extended-release formulation given every 12 hours. Target serum concentration 10-20 mcg/mL.

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.
3–8 hours in adults (mean ~5 h); prolonged in heart failure, liver disease, and COPD; decreased in smokers (4–5 h) and children.
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%).
Renal: approximately 10% unchanged; hepatic metabolism accounts for ~90% of elimination; metabolites excreted in urine.
