KENALOG-40 vs ORALONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory, immunosuppressive, and antiproliferative properties; suppresses cytokine production, inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and stabilizes lysosomal membranes.
ORALONE is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of pro-inflammatory cytokines.
Intra-articular injection: 10-40 mg for large joints, 5-15 mg for medium joints, 2.5-5 mg for small joints. Intralesional injection: 2.5-5 mg per lesion. Intramuscular injection: 40-80 mg once monthly. Not for IV or subcutaneous use.
0.3-0.6 mg/kg IV/IM every 4-6 hours as needed; maximum single dose 30 mg.

Terminal elimination half-life is approximately 2 to 3 hours after IV administration, but due to the triamcinolone acetonide suspension formulation, the effective half-life following intramuscular or intra-articular administration is prolonged to 2-3 weeks due to slow dissolution from the injection site.
1.5–3 hours (mean 2.5 hours) in adults; prolonged to 3–6 hours in hepatic impairment and up to 4 hours in elderly patients.
Primarily hepatic metabolism followed by renal excretion of inactive metabolites. Less than 5% excreted unchanged in urine. Biliary/fecal elimination accounts for approximately 15-20% of total clearance.
Renal: >90% as glucuronide conjugates and unchanged drug (approximately 60% as metabolites, 30% unchanged). Biliary/fecal: <5%.
