DEXAIR vs HI-COR
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.
Corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive actions. Suppresses cytokine production, inhibits phospholipase A2, and reduces prostaglandin and leukotriene synthesis.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
0.1-0.2 mg/kg intravenously once.

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 2-4 hours. Clinical context: Short half-life requires frequent dosing for sustained effect; accumulation possible in renal 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 unchanged drug and metabolites accounts for approximately 70-80% of elimination, with biliary/fecal excretion contributing 20-30%.
