DEXAIR vs HYDROCORTISONE SODIUM SUCCINATE
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.
Hydrocortisone sodium succinate is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to produce anti-inflammatory, immunosuppressive, and anti-stress responses. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
100–500 mg IV or IM every 2–6 hours, as needed; typical initial dose 100–250 mg IV bolus followed by 100–250 mg IV every 4–6 hours for acute conditions.

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).
1.5-2 hours (plasma terminal); biological half-life 8-12 hours (due to intracellular effects), requiring q6-8h dosing in adrenal insufficiency
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal (90-95% as metabolites, <5% unchanged); biliary/fecal <5%
