COLOCORT vs HYDROCORTISONE SODIUM PHOSPHATE
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.
Hydrocortisone sodium phosphate is a corticosteroid that binds to the glucocorticoid receptor, leading to regulation of gene transcription. It inhibits phospholipase A2, reducing pro-inflammatory mediators such as prostaglandins and leukotrienes. It also suppresses immune cell migration and cytokine production.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
100-500 mg intravenously or intramuscularly every 2-6 hours as needed for acute conditions; typical dose 100 mg IV/IM every 8 hours.

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 approximately 1.5–2 hours; in adrenal insufficiency, dose interval is 8 hours due to HPA axis suppression considerations.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal: primarily as inactive metabolites, <1% unchanged; hepatic metabolism to tetrahydrocortisone and glucuronide conjugates; biliary/fecal excretion negligible.
