DEXAIR vs SYNALAR-HP
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, altering gene expression to inhibit inflammatory mediators (e.g., prostaglandins, leukotrienes) and suppress immune cell activity.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
Apply a thin film to the affected area once or twice daily for up to 2 weeks, using the lowest effective dose. Not for use under occlusive dressings or on large areas.

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 half-life: 2-3 hours (topical) due to rapid clearance; systemic half-life: 1-2 hours
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renal: 90% as metabolites; biliary/fecal: minimal (<5%)
