KENALOG-80 vs PARACORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide is a synthetic corticosteroid with potent anti-inflammatory, immunosuppressive, and anti-proliferative effects. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of phospholipase A2, which reduces prostaglandin and leukotriene synthesis. It also suppresses cytokine production and immune cell migration.
Paracort is a corticosteroid that acts by binding to glucocorticoid receptors, leading to modulation of gene expression and suppression of inflammatory mediators such as cytokines and prostaglandins.
60 mg (1.5 mL) intramuscularly (deep IM) as a single dose for allergic/ inflammatory conditions; intra-articular or soft tissue injection: 10-40 mg for large joints, 5-25 mg for medium joints, 2.5-10 mg for small joints; intralesional: up to 1 mg per injection site, repeated as needed.
Prednisone 5-60 mg orally once daily; initial dose 5-15 mg daily; for acute conditions, up to 60 mg daily tapered over 2-3 weeks.

Terminal elimination half-life: 2–4 hours for triamcinolone acetonide; prolonged in hepatic impairment (up to 6–8 hours).
Terminal elimination half-life is 3.5 hours (range 2.5–4.5 hours) in adults with normal renal function; prolonged to up to 10–15 hours in severe renal impairment (CrCl <30 mL/min).
Primarily hepatic metabolism followed by renal excretion of inactive metabolites; less than 5% excreted unchanged in urine, with minor biliary/fecal elimination (<2%).
Renal elimination of unchanged drug accounts for approximately 70% of the dose; biliary/fecal excretion accounts for 20%; the remainder is metabolized and excreted as inactive metabolites.
