Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses multiple inflammatory cytokines and induces lipocortin synthesis.
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.
Intravenous: Initial dose 100-250 mg, then repeat every 10-30 minutes as needed. Intramuscular: 100-250 mg every 10-30 minutes. Intra-articular: 10-40 mg per joint every 1-2 weeks.
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 half-life ~2-3 hours; clinically, adrenal suppression may persist >24h.
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.
Renally eliminated: ~80% as metabolites, <10% unchanged. Biliary/fecal: minor.
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.
