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.
Beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle via increased intracellular cAMP.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
2 inhalations (340 mcg) via oral inhalation every 4-6 hours as needed for bronchospasm; not to exceed 12 inhalations per day.

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.
3.5–4.0 hours; clinically, this supports dosing every 4–6 hours as needed.
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
Renal excretion of unchanged drug accounts for approximately 90% of elimination; fecal excretion is minimal (<5%).
