Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortril (hydrocortisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators and suppression of immune response.
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.
Hydrocortisone (Cortril) for adrenal insufficiency: 20-30 mg orally daily divided into two or three doses. For acute conditions, IV or IM hydrocortisone sodium succinate 100 mg every 8 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: 1.5–2.5 hours. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
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 (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<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.
