DEXAIR vs PREDNISONE
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, leading to altered gene transcription that results in anti-inflammatory and immunosuppressive effects, including suppression of cytokines, prostaglandins, and leukotrienes.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
5-60 mg orally once daily or divided twice daily; for acute indications, initial dose 5-60 mg/day; for chronic conditions, lowest effective dose; route: oral, intravenous, intramuscular.

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 half-life: 2-3 hours (plasma); clinical effects persist for 12-36 hours due to intracellular actions and active metabolite prednisolone (half-life 3-4 hours).
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal: <10% as unchanged drug; hepatic metabolism to inactive glucuronide and sulfate conjugates; fecal: ~20-30% via biliary elimination.
