Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colocort (hydrocortisone acetate) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, and suppression of immune responses.
Glucocorticoid receptor agonist; modulates gene expression to inhibit pro-inflammatory cytokines, phospholipase A2, and NF-κB; suppresses immune response and inflammation.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
5-60 mg orally once daily or divided every 12-24 hours; dose depends on condition and severity. For acute exacerbations, 200-400 mg intramuscularly once.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
Terminal elimination half-life: 2-4 hours (plasma); biological (tissue) half-life: 18-36 hours due to prolonged glucocorticoid receptor-mediated effects. Half-life prolonged in hepatic disease.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal (fraction excreted unchanged: <1%); primarily hepatic metabolism to inactive glucuronide and sulfate conjugates eliminated renally and fecally. After oral administration, 12-15% of dose recovered in bile/feces as metabolites.
