DEXAIR vs HYDELTRASOL
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 with anti-inflammatory and immunosuppressive properties; suppresses multiple inflammatory cytokines and induces lipocortin synthesis.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
Intravenous: Initial dose 100-250 mg, then repeat every 10-30 minutes as needed. Intramuscular: 100-250 mg every 10-30 minutes. Intra-articular: 10-40 mg per joint every 1-2 weeks.

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; clinically, adrenal suppression may persist >24h.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Renally eliminated: ~80% as metabolites, <10% unchanged. Biliary/fecal: minor.
