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 potent glucocorticoid that binds to glucocorticoid receptors, modulating gene expression to inhibit pro-inflammatory cytokines (e.g., IL-1, IL-6, TNF-α) and reduce inflammation, immune response, and adrenal function.
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.
0.75 mg orally once daily, typically as part of a tapering regimen for anti-inflammatory or immunosuppressive effects.

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 elimination half-life: 36-54 hours in adults with normal renal function; prolonged to 72-168 hours in severe renal impairment.
Primarily hepatic metabolism; renal excretion of inactive metabolites (<5% unchanged); minimal biliary/fecal excretion.
Renal: ~65-80% as unchanged drug; Fecal: ~10-15% as metabolites; Minor biliary excretion.
