KENALOG vs STIE-CORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide is a synthetic corticosteroid with potent glucocorticoid and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins and leukotrienes. It also suppresses cytokine production and immune cell migration.
Glucocorticoid receptor agonist; modulates gene expression leading to anti-inflammatory and immunosuppressive effects.
Kenalog (triamcinolone acetonide) 40-80 mg intramuscularly (deep gluteal) every 4 weeks; or 0.5-1 mg/kg intravenously every 24 hours (for acute conditions).
Topical: Apply a thin film to affected area twice daily. Maximum 2-week continuous use. In severe cases, apply up to 4 times daily. Do not exceed 50 g/week.

Terminal half-life ~2-5 hours (triamcinolone acetonide); clinical duration prolonged due to crystalline depot formulation
Terminal elimination half-life is 1.5-2 hours (intravenous) and 2-3 hours (oral), reflecting rapid clearance; clinical context: supports twice-daily dosing for systemic effects.
Renal (primarily as metabolites), ~30% unchanged; biliary/fecal minor (≤10%)
Renal: 60-70% as metabolites; biliary/fecal: 20-30% as metabolites; unchanged drug: <5%.
