Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic corticosteroid with potent glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress 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.
100 mg intravenously every 8 hours for 24 hours, then 50 mg intravenously every 8 hours for 48 hours, followed by 25 mg intravenously every 8 hours for 72 hours.
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 is 2.5–3.5 hours; clinically, this short half-life requires multiple daily dosing for sustained effects.
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.
Primarily renal (80% as metabolites, 20% unchanged); minor biliary/fecal (<5%).
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.
