Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
Dexamethasone sodium phosphate is a glucocorticoid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
4-20 mg IV or IM every 4-6 hours; for cerebral edema: 10 mg IV followed by 4 mg IM/IV every 6 hours; for shock: 20 mg IV initially then 2-6 mg/kg IV bolus or 40 mg IV every 2-6 hours as needed.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
Terminal elimination half-life is 3-4 hours in adults; however, the duration of action extends beyond the plasma half-life due to intracellular receptor-mediated effects.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Renal excretion of unchanged drug and metabolites accounts for approximately 60-70% of elimination; biliary/fecal excretion accounts for 30-40%.
