Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta2-adrenergic receptor agonist; stimulates adenylate cyclase, increasing cAMP, leading to relaxation of bronchial smooth muscle.
Selective beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing intracellular cyclic AMP.
90 mcg (2 inhalations) by oral inhalation every 4 to 6 hours as needed for bronchospasm. For prevention of exercise-induced bronchospasm, 2 inhalations 15 to 30 minutes before exercise.
Inhalation via Rotahaler: 200-400 mcg (1-2 capsules) every 4-6 hours as needed for bronchospasm; maximum 4 times daily.

3-4 hours for systemically absorbed albuterol; terminal half-life is approximately 3.8 hours. No accumulation with repeated dosing.
Terminal elimination half-life: 3-6 hours in adults; prolonged in patients with renal impairment or hepatic dysfunction (up to 12 hours). Clinical context: Dosing interval typically every 4-6 hours.
Renal (60-70% as unchanged drug and metabolites, primarily as sulfate conjugate; biliary/fecal: minor, <10%).
