Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone sodium phosphate is a corticosteroid with potent anti-inflammatory and immunosuppressant properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, inhibition of phospholipase A2, and reduction of inflammatory mediators like prostaglandins and leukotrienes.
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.
0.5-24 mg/day IV or IM in divided doses every 6-12 hours; acute conditions: 4-20 mg IV initially, then 2-4 mg every 4-6 hours.
0.5-1 mg orally three times daily; maximum dose 4 mg/day.

Terminal elimination half-life is 3-4 hours in adults; clinical context: biological effects persist >24 hours due to prolonged receptor binding.
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.
Primarily renal (approximately 65-80% as free steroid and glucuronide conjugates); minor biliary/fecal elimination (10-15%).
Renal, unchanged drug: <1% of dose; metabolites: approximately 20% in urine, remainder in feces via biliary elimination.
