A-HYDROCORT vs DEXAIR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a corticosteroid hormone that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, inhibit immune response, and regulate metabolism.
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.
Adrenal insufficiency: oral 20-30 mg/day in divided doses; inflammatory conditions: 5-60 mg/day oral; IV/IM: hydrocortisone sodium succinate 50-100 mg every 4-6 hours.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.

Terminal half-life: 1.5-2 hours (cortisol); clinical effect persists 8-12 hours due to glucocorticoid receptor binding
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).
Renal (primarily as metabolites, <1% unchanged); biliary/fecal (<5%)
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
