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 by increasing cyclic AMP.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
Isoetharine mesylate 0.5% solution: 2-4 inhalations every 4 hours as needed via hand-held nebulizer or IPPB.

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: 2-3 hours; clinically, bronchodilation persists but dosing interval is 3-4 hours due to rapid onset and offset.
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
Renal: 10-15% unchanged; 70-80% as sulfate conjugates; biliary/fecal: <5%.
