CORTIFOAM vs KENALOG-10
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.
Triamcinolone acetonide is a synthetic corticosteroid with anti-inflammatory, immunosuppressive, and antiproliferative actions. It binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production (e.g., IL-1, IL-2, TNF-alpha). It also stabilizes lysosomal membranes and inhibits fibroblast proliferation.
1 applicatorful (90 mg hydrocortisone acetate) rectally twice daily for 2-3 weeks, then every other day as needed.
Intra-articular, intrabursal, or soft tissue injection: 10-40 mg (0.25-1 mL of 10 mg/mL) for large joints; 10 mg (0.25 mL) for small joints; repeat every 3-4 weeks if needed. Intralesional: 10-40 mg (0.25-1 mL) per lesion; maximum 1 mL per injection site; repeat every 1-2 weeks.

Approximately 1.5-2 hours for hydrocortisone; clinically, effects persist longer due to local action.
Terminal elimination half-life is approximately 2–5 hours for triamcinolone acetonide. However, the duration of action is prolonged due to the crystalline suspension's slow dissolution from the injection site, resulting in a prolonged residence time and effects lasting weeks. The plasma half-life primarily reflects systemic clearance after absorption.
Primarily renal (about 70-90% as metabolites) and fecal (about 10-30% as metabolites).
Primarily hepatic metabolism (~80%) followed by renal excretion of inactive metabolites (glucuronide and sulfate conjugates). Unchanged triamcinolone acetonide accounts for <5% of urinary recovery. Biliary/fecal excretion is minor.
