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.
Methylprednisolone acetate is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene expression to suppress inflammation, immune response, and adrenal function. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and decreases cytokine production.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
40-80 mg intramuscular (IM) or intra-articular (IA) injection; for IM use, dose may be repeated every 1-4 weeks as needed. Maximum single IM dose: 120 mg.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
Terminal half-life: 3-3.5 hours; correlates with duration of anti-inflammatory effect due to receptor-mediated action.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal: <10% unchanged; extensive hepatic metabolism to inactive metabolites primarily excreted renally as glucuronides and sulfates.
