DEXAIR vs STERI-STAT
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.
Binds to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis by blocking peptide bond formation and translocation.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
Adults: 1 gram intravenously every 8 hours infused over 60 minutes.

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).
Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 18-24 hours in moderate renal impairment (CrCl 30-50 mL/min).
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal excretion of unchanged drug accounts for approximately 95% of elimination; biliary/fecal elimination is minimal (<5%).
