ARISTOSPAN vs LIQUID PRED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
Triamcinolone hexacetonide (Aristospan) is administered intra-articularly or intralesionally. For intra-articular use in adults, typical dose is 2–20 mg (0.5–1 mL of 20 mg/mL suspension) depending on joint size. For intralesional use, 2–3 mg per injection site, with total dose not exceeding 0.5 mg/kg per day.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

Triamcinolone hexacetonide: terminal half-life approximately 2-3 weeks (88-144 hours) due to slow release from depot site; clinical effects persist for weeks to months.
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Primarily hepatic metabolism; renal excretion of inactive metabolites (<5% unchanged); minimal biliary/fecal excretion.
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
