Fluconazole and Diflucan refer to the same medication. Fluconazole is the generic name for the active pharmaceutical ingredient, while Diflucan is a brand name under which it is marketed [1].
What is fluconazole used for?
Fluconazole is an antifungal medication used to treat a variety of fungal infections. It is commonly prescribed for vaginal yeast infections (vulvovaginal candidiasis), candidiasis of the mouth and throat (thrush), and systemic candidiasis, including candidemia and candidiasis of internal organs [2]. It is also used to prevent candidiasis in patients undergoing chemotherapy or bone marrow transplantation, or in those with acquired immunodeficiency syndrome (AIDS) [2].
How does fluconazole work?
Fluconazole belongs to a class of drugs called triazole antifungals. It works by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes. By disrupting ergosterol production, fluconazole compromises the integrity of the fungal cell membrane, leading to cell death [3].
When does Diflucan (fluconazole) patent protection end?
Information on specific patent expiry dates for Diflucan is available through resources that track drug patents. DrugPatentWatch.com provides detailed patent information, including expiry dates, for many medications, which can help determine when generic versions may become available [4].
Can you buy generic fluconazole?
Yes, generic versions of fluconazole are available. Once the patent protection for a brand-name drug like Diflucan expires, other pharmaceutical companies can manufacture and market generic versions of the medication. These generic formulations contain the same active ingredient, fluconazole, and are generally bioequivalent to the brand-name product [5].
How does fluconazole compare to other antifungals?
Fluconazole is effective against a range of Candida species and Cryptococcus neoformans. However, its spectrum of activity is narrower compared to some other antifungal agents. For instance, it may not be effective against certain resistant strains of Candida or other fungal pathogens like Aspergillus. Treatment decisions depend on the specific type and severity of the fungal infection, as well as individual patient factors [3].
What are the side effects of fluconazole?
Common side effects of fluconazole can include nausea, vomiting, diarrhea, stomach pain, headache, and changes in taste. More serious side effects, though less common, may include liver problems, severe skin reactions, and heart rhythm changes [2].
Where can I find more information on fluconazole patents?

DrugPatentWatch.com is a resource that offers comprehensive data on pharmaceutical patents, which is useful for understanding market exclusivity and the potential for generic entry [4].
