Terconazole

Introduction: What is Terconazole?

Terconazole is an antifungal medication primarily used to treat fungal infections, particularly those caused by Candida species. It belongs to a class of drugs known as azole antifungals, which work by inhibiting the growth of fungi. Terconazole is prescribed for vulvovaginal candidiasis (vaginal yeast infections) and is available in vaginal cream (0.4%, 0.8%) and suppository (80 mg) formulations.

Uses of Terconazole

Terconazole is primarily indicated for the treatment of:

• Vaginal Candidiasis: This is the most common use, where Terconazole effectively treats yeast infections in the vaginal area.

How Does It Work?

Terconazole works by disrupting the synthesis of ergosterol, a vital component of fungal cell membranes. By inhibiting the enzyme lanosterol demethylase, Terconazole prevents the formation of ergosterol, leading to increased membrane permeability and ultimately causing cell death in fungi. In simpler terms, it stops the fungi from growing and spreading, helping to clear the infection.

Dosage and Administration

The standard dosage of Terconazole varies based on the formulation:

• Vaginal Cream: 0.8% cream (5 g applicator) intravaginally at bedtime for 3 consecutive days; or 0.4% cream (5 g applicator) as a single dose.
• Vaginal Suppository: 80 mg suppository intravaginally at bedtime for 3 consecutive days.

Terconazole is not indicated for prepubertal pediatric patients.
