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

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