DEXONE 4 vs TRIESENCE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
Corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating cytokine production.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
1 to 4 mg (0.025 to 0.1 mL of 40 mg/mL suspension) intravitreal injection once.

Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
Approximately 3.3 hours for triamcinolone acetonide; with intravitreal administration, detectable levels persist for weeks to months.
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
Primarily hepatic metabolism; renal excretion of metabolites (<5% unchanged). Biliary/fecal elimination accounts for minimal clearance.
