DEXAIR vs STIE-CORT
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.
Glucocorticoid receptor agonist; modulates gene expression leading to anti-inflammatory and immunosuppressive effects.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
Topical: Apply a thin film to affected area twice daily. Maximum 2-week continuous use. In severe cases, apply up to 4 times daily. Do not exceed 50 g/week.

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 1.5-2 hours (intravenous) and 2-3 hours (oral), reflecting rapid clearance; clinical context: supports twice-daily dosing for systemic effects.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal: 60-70% as metabolites; biliary/fecal: 20-30% as metabolites; unchanged drug: <5%.
