Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
Triacetin is a triester of glycerol and acetic acid. Its exact mechanism of action is not fully understood, but it exhibits antifungal activity by disrupting fungal cell membrane integrity and inhibiting fungal growth.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life is approximately 3.5–4 hours in adults with normal renal function; may be prolonged (up to 6–8 hours) in patients with hepatic impairment.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Renal, unchanged drug: <1% of dose; metabolites: approximately 20% in urine, remainder in feces via biliary elimination.
