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.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
0.5 mg orally once daily, with gradual taper to lowest effective dose

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
