Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta2-adrenergic receptor agonist that relaxes bronchial smooth muscle by increasing cyclic AMP production via adenylate cyclase activation.
Selective beta-2 adrenergic receptor agonist that relaxes bronchial smooth muscle by increasing intracellular cyclic AMP levels.
AEROLONE is not a recognized drug; no standard dosing available.
Nebulized solution: 0.63 mg or 1.25 mg 3 times daily every 6-8 hours; metered-dose inhaler: 2 inhalations (90 mcg per inhalation) 3 times daily every 6-8 hours.

Terminal elimination half-life is approximately 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life: 3.3-4.0 hours in adults. Clinically, twice-daily dosing is not recommended due to shorter half-life; every 4-6 hour dosing is standard for acute bronchodilation.
Primarily renal excretion of unchanged drug (approximately 65%) and hepatic metabolism (35%), with metabolites excreted in urine and feces. Biliary/fecal elimination accounts for <10%.
Renal: 80-100% as unchanged drug and metabolites (approximately 60% as unchanged levalbuterol, 20% as inactive sulfate conjugate). Fecal: <5%.
