CANDEX vs NIZORAL ANTI-DANDRUFF
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.
Ketoconazole, an imidazole antifungal agent, inhibits fungal cytochrome P450 14α-demethylase (CYP51), preventing the conversion of lanosterol to ergosterol, an essential component of fungal cell membranes. This disrupts membrane integrity and function.
Adults: 150 mg orally once daily
Apply to wet hair, lather, and leave on for 3-5 minutes before rinsing. Use twice weekly for 4 weeks, then as needed to control dandruff.

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 is biphasic: initial 2 hours, terminal 8 hours (range 6-10 hours). After topical application, systemic absorption is minimal, resulting in an effective half-life of 72-96 hours in skin.
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.
Primarily fecal (57%) via biliary excretion as unchanged drug and metabolites; renal excretion accounts for approximately 13% (2-4% unchanged).
