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.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.
1.5 mg orally once 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 half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
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, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
