CORTIFOAM vs MEDROL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortifoam (hydrocortisone acetate) is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, antipruritic, and vasoconstrictive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses immune cell migration and cytokine release.
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines (e.g., IL-1, IL-2, TNF-alpha). It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis.
1 applicatorful (90 mg hydrocortisone acetate) rectally twice daily for 2-3 weeks, then every other day as needed.
4 to 48 mg orally once daily or every other day, depending on condition. Initial dose may be up to 48 mg/day.

Approximately 1.5-2 hours for hydrocortisone; clinically, effects persist longer due to local action.
Terminal half-life of methylprednisolone is 2.5-3.5 hours; for the active metabolite (prednisolone), half-life is 2.1-3.5 hours. Clinical context: Despite short half-life, pharmacodynamic effects persist beyond plasma presence due to receptor-mediated actions.
Primarily renal (about 70-90% as metabolites) and fecal (about 10-30% as metabolites).
Renal (approximately 80-90% as metabolites, <5% unchanged); biliary/fecal (minor, <5%)
