COLOCORT vs PREDNISOLONE
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.
Prednisolone is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, inhibition of phospholipase A2, and reduction of prostaglandin and leukotriene synthesis.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
Initial adult dose: 5-60 mg orally, intramuscularly, or intravenously daily, divided into 2-4 doses; maintenance: 2.5-15 mg daily.

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: 2.1-3.5 hours in adults; prolonged in hepatic impairment (up to 12 hours) or with concurrent estrogen use.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal (primarily as glucuronide and sulfate conjugates; <20% as unchanged prednisolone); biliary/fecal (minor, <5%).
