What is Fentizol VT 600 mg?
Fentizol VT 600 mg is a vaginal tablet containing the active ingredient fenticonazole nitrate, a broad-spectrum antifungal agent from the imidazole class. This medication is specifically formulated for intravaginal administration to treat various infections within the genital area. Fenticonazole is effective not only against fungi and yeasts but also against certain gram-positive bacteria and the protozoan Trichomonas vaginalis, making it a versatile option for mixed vaginal infections.
The formulation as a vaginal tablet (VT) ensures the medication is delivered directly to the site of infection, providing targeted action with minimal systemic absorption. This approach helps to concentrate the therapeutic effect where it is needed most, leading to effective eradication of the causative pathogens and a reduction in associated symptoms like itching, burning, and discharge.
Primary Uses and Indications
Fentizol VT 600 mg is prescribed for several specific types of vaginal infections:
- Genital Candidiasis: This is a common yeast infection of the vulva and vagina, often caused by the Candida albicans species. Symptoms typically include severe itching, burning, and a thick, white vaginal discharge.
- Trichomoniasis: This is a sexually transmitted infection caused by the protozoan parasite Trichomonas vaginalis. It can cause itching, burning, redness, and a strong-smelling discharge.
- Mixed Vaginal Infections: Fentizol is also indicated for infections where both Trichomonas vaginalis and Candida albicans are present simultaneously. Its broad-spectrum activity makes it an effective choice for treating these complex infections.
Mechanism of Action: How Fenticonazole Works
The efficacy of fenticonazole nitrate lies in its multi-pronged attack on infectious agents. It employs several mechanisms to disrupt the life cycle and structure of fungi, bacteria, and protozoa, including:
- Inhibition of Ergosterol Biosynthesis: Fenticonazole inhibits the fungal cytochrome P450 enzyme lanosterol 14α-demethylase. This prevents the conversion of lanosterol into ergosterol, a vital component of the fungal cell membrane. Without a properly formed cell membrane, the fungal cell becomes unstable and eventually dies.
- Damage to Fungal Cell Membrane: The disruption of ergosterol synthesis increases the permeability of the fungal cell membrane, leading to the leakage of cellular contents. This effectively kills the fungal cell and is a key fungicidal action.
- Inhibition of Aspartic Protease Secretion: Fenticonazole also prevents the secretion of acid protease enzymes by Candida species. This reduces the ability of the fungi to adhere to vaginal mucosa and penetrate tissue, thereby limiting the infection's spread and preventing recurrence.
- Effect on Oxidative and Peroxidative Enzymes: The medication also causes changes in the activity of certain oxidative and peroxidative enzymes within the fungal cell, leading to the buildup of toxic hydrogen peroxide and necrosis.

Proper Administration and Precautions
For Fentizol VT 600 mg to be most effective, proper use is essential. The vaginal tablet should be inserted deep into the vagina using the provided applicator. Completing the full prescribed course is crucial, even if symptoms improve quickly, to ensure the infection is completely cleared. Patients should also avoid sexual intercourse during treatment, as the medication can weaken latex products like condoms and diaphragms. Concurrent treatment for the sexual partner with a similar azole cream is often recommended to prevent re-infection.
Contraindications include hypersensitivity to fenticonazole or other imidazole derivatives. Use during pregnancy and lactation is not recommended unless specifically advised by a doctor, due to insufficient data on safety. Common side effects are generally mild and localized, such as a transient burning sensation or irritation at the application site. If more persistent irritation occurs, treatment should be suspended, and a doctor consulted.
Conclusion
In conclusion, Fentizol VT 600 mg is a highly effective, broad-spectrum antifungal medication indicated for the treatment of various vaginal infections, including candidiasis, trichomoniasis, and mixed infections. Its active ingredient, fenticonazole, works through multiple mechanisms to inhibit fungal growth and eradicate pathogens. While generally well-tolerated, it is vital to follow a healthcare provider's instructions carefully for proper administration and to minimize potential side effects. Its broad-spectrum action makes it a suitable single-agent therapy for mixed infections.
