Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing 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.
1-2 mL (6-12 mg/mL betamethasone acetate and betamethasone sodium phosphate) intramuscularly or intralesionally, repeat every 1-4 weeks as needed.
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).

Plasma terminal half-life: betamethasone phosphate ~3-5 hours; betamethasone acetate ~6-8 hours. Clinical duration extended due to ester hydrolysis and depot effect (up to 7-14 days for IM injection).
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% as metabolites and unchanged drug; biliary/fecal: ~20%; remainder via other pathways.
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.
