Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colocort (hydrocortisone acetate) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, and suppression of immune responses.
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.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
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.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
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.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
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%.
