Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta-2 adrenergic receptor agonist that stimulates adenylyl cyclase, increasing cAMP levels, leading to bronchodilation.
Corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, decreased prostaglandin and leukotriene synthesis, and suppression of inflammatory cytokines.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.
Intramuscular: 40-80 mg every 4 weeks. Intra-articular: 5-40 mg depending on joint size. Topical: Apply thin film to affected area 2-4 times daily.

Terminal elimination half-life is 3-5 hours in patients with normal renal function; prolonged to 10-20 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life approximately 2-5 hours; but suppression of adrenal function (HPA axis) can persist for 7-30 days depending on dose and duration.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; the remainder undergoes hepatic metabolism.
Renal (primarily as metabolites, <5% unchanged); biliary/fecal (minor).
