DEXACORT vs TRIACET
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.
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.
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.
0.5-1 mg orally three times daily; maximum dose 4 mg/day.

Plasma 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
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 (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal, unchanged drug: <1% of dose; metabolites: approximately 20% in urine, remainder in feces via biliary elimination.
