Fluconazole vs NIZORAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluconazole is a triazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane.
Inhibits fungal CYP51 (lanosterol 14α-demethylase), blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
200-400 mg orally or intravenously once daily. For candidemia and other invasive Candida infections, loading dose of 800 mg (12 mg/kg) on day 1, then 400 mg (6 mg/kg) daily.
Ketoconazole 200 mg orally once daily with food. For severe infections, increase to 400 mg once daily. Duration depends on indication.

Terminal elimination half-life ~30 hours (range 20-50 h) in patients with normal renal function; prolonged in renal impairment (up to 98 h in CrCl <20 mL/min). This long half-life supports once-daily dosing and allows loading dose administration.
Biphasic elimination: initial half-life ~2 hours, terminal half-life 6–10 hours in adults with normal hepatic function; prolonged in hepatic impairment.
Renal: approximately 80% as unchanged drug; biliary/fecal: ~11% as metabolites and unchanged drug.
Approximately 70% of the dose is excreted unchanged in feces via biliary elimination, and about 20–35% is excreted in urine, with less than 1% as unchanged drug in urine.
