Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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 acetonide is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and stabilizing lysosomal membranes. It also decreases vascular permeability and inhibits cytokine release.
0.75 mg orally once daily, typically as part of a tapering regimen for anti-inflammatory or immunosuppressive effects.
The recommended dose is 0.1 mL (containing 0.16 mg triamcinolone acetonide injectable suspension) administered by suprachoroidal injection to the affected eye(s) once every 3 months (every 12 weeks).

Terminal elimination half-life: 36-54 hours in adults with normal renal function; prolonged to 72-168 hours in severe renal impairment.
The terminal elimination half-life of triamcinolone acetonide following suprachoroidal administration is approximately 18 hours. This short half-life allows for sustained local effect with minimal systemic accumulation.
Renal: ~65-80% as unchanged drug; Fecal: ~10-15% as metabolites; Minor biliary excretion.
XIPERE (triamcinolone acetonide injectable suspension) is primarily eliminated via hepatic metabolism and subsequent renal excretion of metabolites. Approximately 40% of the dose is excreted renally as metabolites, with less than 5% as unchanged drug. Biliary/fecal excretion accounts for about 60% of the dose, mainly as metabolites.
