CORTENEMA vs KENALOG-H
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
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.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
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.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
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.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
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%.
