Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline competitively inhibits phosphodiesterase, increasing cAMP levels, and acts as an adenosine receptor antagonist, leading to bronchodilation and reduced airway inflammation.
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.
For asthma and COPD: 1-2 inhalations (90 mcg each) via metered-dose inhaler, 2 puffs twice daily, maximum 4 puffs twice daily. For acute exacerbations: 4-8 puffs every 20 minutes for up to 4 hours, then every 1-4 hours as needed.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.

Terminal elimination half-life 12 hours; clinical context: q12h dosing achieves steady-state in 2-3 days
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.
Renal (80% as unchanged drug), biliary/fecal (15% as metabolites), 5% other
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
