DEXAIR vs EMFLAZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DEXAIR (dexamethasone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., cytokines, prostaglandins). It also inhibits leukocyte infiltration and reduces capillary permeability.
Agonist at glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
0.6 mg/kg orally once daily (maximum 60 mg/day); titrate to lowest effective dose based on clinical response.

Terminal elimination half-life: 3.0-4.5 hours in adults with normal renal function; prolonged to 8-12 hours in severe renal impairment (CrCl <30 mL/min).
6.2 hours (range 4.5–8.1 h) in healthy adults; prolonged in hepatic impairment.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal excretion of inactive metabolites; less than 5% excreted as unchanged drug in urine. Biliary/fecal elimination accounts for <1%.
