Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline is a xanthine derivative that acts as a bronchodilator by relaxing bronchial smooth muscle. Its mechanism may involve inhibition of phosphodiesterase, increasing cyclic AMP, and adenosine receptor antagonism.
Theophylline relaxes bronchial smooth muscle by inhibiting phosphodiesterase, increasing intracellular cAMP, and antagonizing adenosine receptors.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
100 mg orally every 6 hours; adjust based on serum theophylline concentrations and clinical response (target 5-15 mcg/mL).

Terminal elimination half-life: 3.5-4.5 hours. This short half-life supports twice-daily dosing in asthma management, with trough levels remaining above therapeutic threshold.
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.
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
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%).
