DEXACORT vs TRIAMCINOLONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Synthetic glucocorticoid with anti-inflammatory, immunosuppressive, and anti-allergic effects. Binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.
Intramuscular: 40-80 mg as a single dose; Intra-articular: 5-40 mg depending on joint size; Topical: Apply thin layer 2-4 times daily; Oral: 4-48 mg/day in divided doses.

Clinical Note
moderatePlasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
The terminal elimination half-life of triamcinolone is approximately 2-5 hours (mean 3 hours) following intravenous administration. Clinically, this short half-life supports multiple daily dosing for systemic effects, but duration of action is longer due to receptor occupancy.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Triamcinolone is primarily metabolized hepatically; unchanged drug and metabolites are excreted renally. Approximately 25-30% of a dose is excreted in urine as unchanged triamcinolone, with the remainder as metabolites. Fecal excretion accounts for less than 10%.
