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.
Inhibits phosphodiesterase, increasing cAMP levels, leading to bronchodilation and reduced airway inflammation.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
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: 3.5-4.5 hours. This short half-life supports twice-daily dosing in asthma management, with trough levels remaining above therapeutic threshold.
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 elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
Renal: approximately 10% unchanged; hepatic metabolism accounts for ~90% of elimination; metabolites excreted in urine.
