How Fluconazole Tablet Works

Fluconazole, a synthetic triazole antifungal, has an influence on fungal cell membranes. It works by inhibiting the enzyme lanosterol 14-α-demethylase, which is crucial for ergosterol production. Ergosterol is an integral part of fungal cell membranes. By blocking this enzyme, fluconazole stops the conversion of lanosterol to ergosterol, leading to increased membrane permeability and cell leakage. This process ultimately results in the arrest of fungal growth. Fluconazole's action is fungistatic, meaning it stops fungi from growing rather than killing them directly. This mechanism makes fluconazole effective against various fungal infections, including those caused by Candida species.

Can I Take Fluconazole with Other Medicines?

Fluconazole can interact with various medications, so you must inform your doctor about all ongoing medicines. Some drugs should not be used with fluconazole, while others may require dose adjustments or close monitoring, such as:

• Antidepressants
• Carbamazepine
• Chlorpromazine
• Cyclosporine
• Donepezil
• Fentanyl
• Lomitapide
• Macrolide antibiotics like erythromycin
• Medications that may affect heart rhythm, such as pimozole, amiodarone, or quinidine
• Phenytoin
• Tacrolimus
• Theophylline
• Voriconazole
• Warfarin
• Zidovudine

Dosing Information

Fluconazole dosage varies based on the type and severity of infection. For cryptococcal meningitis, the adult dose is 400 mg on the first day of treatment, then 200 mg daily for 10-12 weeks. Children's doses are weight-based.

For oesophagal candidiasis, adults usually take 200 mg on day one, then 100 mg a day for at least three weeks.

Oropharyngeal candidiasis treatment in adults involves 200 mg on the first day, followed by 100 mg daily for at least two weeks.

For vaginal candidiasis, doctors generally prescribe a single fluconazole 150 mg tablet.

Conclusion

Fluconazole has proven to be a versatile and effective medication in the fight against various fungal infections. Its wide range of uses, from common yeast infections to more severe systemic infections, underscores its importance in modern medicine. The drug's mechanism of action, which targets the fungal cell membrane, influences its ability to combat different types of fungi effectively.

As with any medication, it's crucial to use fluconazole under the guidance of a doctor. Understanding the precautions and potential interactions with other medicines is essential to ensure safe and effective treatment.
