Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; modulates gene expression to suppress inflammation, immune response, and reduce capillary permeability.
Beta-2 adrenergic receptor agonist that stimulates adenylyl cyclase, increasing cAMP levels, leading to bronchodilation.
0.5-9 mg/day IV or IM in divided doses every 12-24 hours; acute conditions may require 4-8 mg IV initially.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.

Terminal elimination half-life: 5-6 hours (plasma); biological half-life (HPA axis suppression): 24-36 hours.
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).
Renal: 90-95% as inactive metabolites; biliary/fecal: <5%.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; the remainder undergoes hepatic metabolism.
