Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, reduced prostaglandin and leukotriene synthesis, and suppression of inflammatory mediators.
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.
2-40 mg (0.1-1 mL) intra-articular, intralesional, or soft tissue injection; intra-articular dose depends on joint size (large joint: 10-40 mg, medium joint: 5-25 mg, small joint: 2-10 mg); repeat every 2-3 weeks as needed.
0.5-1 mg orally three times daily; maximum dose 4 mg/day.

The terminal elimination half-life is approximately 2-3 hours for triamcinolone acetonide. In the context of intra-articular or intralesional administration, the half-life at the site of action is prolonged due to slow release from the injection depot, providing sustained local effects.
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 excretion of metabolites (primarily conjugated and unconjugated) accounts for approximately 80-90% of an administered dose, with less than 5% excreted unchanged in urine. Biliary/fecal elimination accounts for the remainder, about 10-20%.
Renal, unchanged drug: <1% of dose; metabolites: approximately 20% in urine, remainder in feces via biliary elimination.
