Fluconazole vs TERAZOL 3
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.
Terconazole is an azole 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. This disrupts membrane integrity and leads to fungal cell death.
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.
One applicatorful (approximately 5 g of 0.8% terconazole vaginal cream) intravaginally once daily at bedtime for 3 consecutive days.

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.
The terminal elimination half-life after intravaginal application is approximately 4-6 hours, reflecting local retention and slow systemic absorption of the small absorbed fraction.
Renal: approximately 80% as unchanged drug; biliary/fecal: ~11% as metabolites and unchanged drug.
Following intravaginal administration, terconazole is minimally absorbed (<5%) into systemic circulation. Absorbed drug is primarily metabolized in the liver and excreted via feces (approximately 50-60% as metabolites) and urine (approximately 20-30% as metabolites). Unabsorbed drug is excreted in feces.
