DEXAIR vs TRIAMCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DEXAIR (dexamethasone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., cytokines, prostaglandins). It also inhibits leukocyte infiltration and reduces capillary permeability.
Corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, decreased prostaglandin and leukotriene synthesis, and suppression of inflammatory cytokines.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
Intramuscular: 40-80 mg every 4 weeks. Intra-articular: 5-40 mg depending on joint size. Topical: Apply thin film to affected area 2-4 times daily.

Terminal elimination half-life: 3.0-4.5 hours in adults with normal renal function; prolonged to 8-12 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life approximately 2-5 hours; but suppression of adrenal function (HPA axis) can persist for 7-30 days depending on dose and duration.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal (primarily as metabolites, <5% unchanged); biliary/fecal (minor).
