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.
Formoterol is a long-acting beta2-adrenergic receptor agonist that stimulates intracellular adenyl cyclase, increasing cyclic AMP production and causing bronchodilation.
1-2 inhalations (35-50 mcg/inhalation) twice daily via oral inhalation.
One inhalation (12 mcg) twice daily via oral inhalation.

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.
The terminal elimination half-life of formoterol (active component) ranges from 5 to 10 hours following inhalation. This supports twice-daily dosing, though clinical effect may persist longer due to prolonged receptor binding.
Renal elimination: 60-70% as unchanged drug and metabolites. Biliary/fecal excretion: 20-30%.
After oral inhalation, the majority of a dose is excreted in feces (up to 70%) as unchanged drug and metabolites via biliary elimination. Renal excretion accounts for approximately 13-25% of the dose, primarily as metabolites. Unabsorbed drug accounts for the remainder.
