CANDEX vs DEXAIR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Candesartan is an angiotensin II receptor blocker (ARB) that selectively binds to the AT1 receptor, inhibiting the vasoconstrictor and aldosterone-secreting effects of angiotensin II, leading to vasodilation and reduced blood pressure.
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.
Adults: 150 mg orally once daily
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.

Terminal elimination half-life is 20-30 hours (mean 24 hours) in adults; prolonged in hepatic impairment (up to 50 hours) and requires dose adjustment.
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).
Primarily hepatic metabolism via CYP2C9, with <1% excreted unchanged in urine. Approximately 70-80% eliminated in feces as metabolites, 20-30% in urine as metabolites.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
