Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits phosphodiesterase, increasing cAMP levels, leading to bronchodilation and reduced airway inflammation.
Selective beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing intracellular cyclic AMP via activation of adenylyl cyclase.
Oral: 400-800 mg every 6-8 hours; extended-release formulation given every 12 hours. Target serum concentration 10-20 mcg/mL.
2 inhalations (90 mcg each) every 4-6 hours as needed via oral inhalation. Maximum 12 inhalations per 24 hours.

3–8 hours in adults (mean ~5 h); prolonged in heart failure, liver disease, and COPD; decreased in smokers (4–5 h) and children.
Terminal elimination half-life: 3-4 hours; clinical context: dosing every 4-6 hours for bronchodilation
Renal: approximately 10% unchanged; hepatic metabolism accounts for ~90% of elimination; metabolites excreted in urine.
Renal: 80-100% as unchanged drug and metabolites; fecal: minimal (<5%)
