CANDEX vs RAYOS
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.
Synthetic glucocorticoid with anti-inflammatory, immunosuppressive, and metabolic effects; binds to glucocorticoid receptor, modulating gene expression and inhibiting phospholipase A2, cytokine production, and immune cell activity.
Adults: 150 mg orally once daily
Initial adult dose 5-60 mg orally once daily, adjusted based on disease severity and response. Typically administered as a single dose in the morning with food.

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.
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
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: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
