Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing cyclic AMP
Selective long-acting beta2-adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing cyclic AMP.
Inhalation: 2 inhalations (90 mcg each) every 4-6 hours as needed; oral: 2-4 mg three to four times daily; extended-release: 4-8 mg every 12 hours.
50 mcg (2 inhalations) twice daily via inhalation; maximum 100 mcg/day.

Terminal elimination half-life: 3.8–6 hours (inhalation), 3.7–7.1 hours (oral); clinical context: supports dosing every 4–6 hours as needed.
Terminal elimination half-life of 5.5 hours (range 3–7 hours). No dose adjustment in renal or hepatic impairment; accumulation can occur in severe hepatic disease, monitor.
Renal: ~90% (mostly as sulfate conjugates after oral administration, unchanged drug after inhalation); biliary/fecal: <10%.
Primarily hepatic metabolism via CYP3A4; ~60% excreted in feces as parent drug and metabolites; ~25% in urine as metabolites; negligible (0.5%) unchanged drug in urine.
