Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clotrimazole, an azole antifungal, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing membrane permeability.
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.
Clotrimazole 100 mg vaginal tablet inserted intravaginally once daily at bedtime for 7 days.
One applicatorful (approximately 5 g of 0.8% terconazole vaginal cream) intravaginally once daily at bedtime for 3 consecutive days.

The systemic half-life of clotrimazole following vaginal administration is approximately 0.5–1 hour due to rapid metabolism and elimination. This short half-life reflects minimal systemic absorption (3–10%).
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.
Primarily via feces as unchanged drug (approx. 50%) and metabolites. Renal excretion of unchanged drug is minimal (<1%) as the drug is poorly absorbed from the vagina. Biliary excretion contributes to fecal elimination.
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.
