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 imidazole antifungal agent that inhibits the synthesis of ergosterol, a key component of fungal cell membranes, by inhibiting the enzyme lanosterol 14α-demethylase. This disruption increases membrane permeability and leads to fungal cell death.
Clotrimazole 100 mg vaginal tablet inserted intravaginally once daily at bedtime for 7 days.
Intravaginal: One full applicator (approximately 5 g of cream containing 40 mg of terconazole) inserted vaginally once daily at bedtime for 7 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%).
Terminal elimination half-life is approximately 7-10 hours; clinically, it allows for once-daily vaginal application, but systemic accumulation is minimal with vaginal dosing.
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.
Primarily fecal (approximately 60%) as unchanged drug and metabolites; renal excretion accounts for about 20% (mostly metabolites).
