Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
Triamcinolone hexacetonide (Aristospan) is administered intra-articularly or intralesionally. For intra-articular use in adults, typical dose is 2–20 mg (0.5–1 mL of 20 mg/mL suspension) depending on joint size. For intralesional use, 2–3 mg per injection site, with total dose not exceeding 0.5 mg/kg per day.
1.5 mg orally once daily

Triamcinolone hexacetonide: terminal half-life approximately 2-3 weeks (88-144 hours) due to slow release from depot site; clinical effects persist for weeks to months.
Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
Primarily hepatic metabolism; renal excretion of inactive metabolites (<5% unchanged); minimal biliary/fecal excretion.
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
