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.
Selective beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing intracellular cyclic AMP via activation of adenylyl cyclase.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
2 inhalations (90 mcg each) every 4-6 hours as needed via oral inhalation. Maximum 12 inhalations per 24 hours.

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: 3-4 hours; clinical context: dosing every 4-6 hours for bronchodilation
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
Renal: 80-100% as unchanged drug and metabolites; fecal: minimal (<5%)
