Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bronchodilator via beta-2 adrenergic receptor agonism, increasing intracellular cAMP, leading to smooth muscle relaxation in the airways.
Formoterol is a long-acting beta2-adrenergic receptor agonist that stimulates intracellular adenyl cyclase, increasing cyclic AMP production and causing bronchodilation.
2.5 mg (0.5 mL of 0.5% solution) via nebulization three to four times daily, as needed.
One inhalation (12 mcg) twice daily via oral inhalation.

Terminal elimination half-life is 3–4 hours; prolonged in hepatic impairment (up to 8 hours).
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.
Primarily renal excretion as sulfate conjugates; unchanged drug accounts for <10% of excretion. Biliary/fecal excretion is minimal (<2%).
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.
