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.
Bronchodilator via beta-2 adrenergic receptor agonism; increases cAMP, relaxes bronchial smooth muscle.
2.5 mg (0.5 mL of 0.5% solution) via nebulization three to four times daily, as needed.
5 mg orally twice daily, increased to 10 mg twice daily after one week if tolerated; maximum dose 20 mg twice daily.

Terminal elimination half-life is 3–4 hours; prolonged in hepatic impairment (up to 8 hours).
Terminal elimination half-life is 7–9 hours in adults with normal hepatic function; prolonged to 20–30 hours in hepatic cirrhosis or heart failure. In neonates, half-life may exceed 30 hours due to immature CYP450 enzymes.
Primarily renal excretion as sulfate conjugates; unchanged drug accounts for <10% of excretion. Biliary/fecal excretion is minimal (<2%).
Primarily hepatic metabolism (CYP1A2, CYP3A4) with renal excretion of metabolites. Less than 10% excreted unchanged in urine; approximately 70% recovered in urine as metabolites, 30% in feces.
