How Does Fluconazole 100 Mg Work? Fast Relief Answers

Fluconazole 100 mg is an antifungal medication that belongs to the triazole class. It works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes. Ergosterol is essential for maintaining the integrity and function of the cell membrane, and its depletion leads to cell lysis and death.

Mechanism of Action

The mechanism of action of fluconazole involves the inhibition of the enzyme lanosterol 14α-demethylase, which is responsible for converting lanosterol to ergosterol. This enzyme is a part of the cytochrome P450 system and is essential for the synthesis of ergosterol. By inhibiting this enzyme, fluconazole depletes the fungal cells of ergosterol, leading to a disruption in cell membrane function and ultimately causing cell death.

Spectrum of Activity

Fluconazole has a broad spectrum of activity against various fungal pathogens, including:

• Candida albicans: a common cause of vaginal yeast infections, oral thrush, and cutaneous candidiasis
• Cryptococcus neoformans: a cause of cryptococcal meningitis, particularly in immunocompromised individuals
• Coccidioides immitis: a cause of coccidioidomycosis, a fungal infection that affects the lungs

Pharmacokinetics

Fluconazole is available in oral and intravenous formulations. After oral administration, fluconazole is rapidly absorbed, with peak plasma concentrations achieved within 1-2 hours. It has a long half-life of approximately 30 hours, which allows for once-daily dosing. Fluconazole is widely distributed throughout the body, including the central nervous system, and is excreted primarily in the urine.

Indications and Dosage

Fluconazole 100 mg is indicated for the treatment of various fungal infections, including:

• Vaginal yeast infections: a single dose of 150 mg
• Oropharyngeal candidiasis: 100 mg once daily for 7-14 days
• Esophageal candidiasis: 100 mg once daily for 14-21 days
• Cryptococcal meningitis: 400 mg once daily for 6-12 months

Side Effects and Interactions

Fluconazole is generally well-tolerated, but common side effects include:

• Nausea and vomiting
• Diarrhea
• Abdominal pain
• Headache

Fluconazole can interact with various medications, including:

• Warfarin: increased risk of bleeding
• Phenytoin: increased risk of phenytoin toxicity
• Cyclosporine: increased risk of cyclosporine toxicity

Conclusion

In conclusion, fluconazole 100 mg is an effective antifungal medication that works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes. Its broad spectrum of activity, favorable pharmacokinetics, and relatively low toxicity make it a popular choice for the treatment of various fungal infections.
