Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses inflammatory cytokines and immune cell activity.
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.
IV or IM: 10-40 mg methylprednisolone (as sodium succinate) every 4-6 hours; high-dose pulse therapy: 30 mg/kg IV over 30-60 minutes every 4-6 hours for 48-72 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: 2.5–3.5 hours. In clinical context, the biologic half-life (suppression of HPA axis) is longer (24–36 hours) due to tissue retention of active metabolites.
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: approximately 80% as metabolites (glucuronide and sulfate conjugates) and unchanged drug; biliary/fecal: less than 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.
