DEXAIR vs DEXAMETHASONE INTENSOL
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 that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of prostaglandins and leukotrienes, and modulation of gene transcription.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
0.75-9 mg/day orally in divided doses every 6-12 hours; for anti-inflammatory/immunosuppressive effects, initial dose 0.75-9 mg/day; for cerebral edema, 10 mg IV then 4 mg IM/IV every 6 hours.

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: 36-54 hours (adults); clinically, biological half-life (duration of HPA axis suppression) is longer (24-72 hours).
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal (approximately 65-80% as metabolites, <10% as unchanged drug); biliary/fecal (minor).
