Antifungal Agents

Fungi are eukaryotes, and they share many of the structural and metabolic characteristics of human cells. As a result, designing agents that affect fungi without harming human cells has proved difficult. One major difference between the two cell types is the primary sterol building block used to form the plasma membrane. The fungal plasma membrane consists of ergosterols; the major sterol component of the human plasma membrane is cholesterol.

Antimicrobial therapy: general principles

A wide variety of antimicrobial agents is available to treat established infections caused by bacteria, fungi, viruses, or parasites. This section will cover the general principles of antimicrobial therapy and will also include illustrative clinical problems to emphasize proper decision-making in using antimicrobials.

Flucytosine (Ancobon 250, 500mg)

While flucytosine may be effective when used alone for the treatment of some fungal infections (e.g., candidal cystitis, chromomycosis), the drug should not be used alone in the treatment of severe, life-threatening infections. In the treatment of serious candidal or cryptococcal infections, flucytosine generally has been used as an adjunct to IV amphotericin B or an azole antifungal agent (e.g., fluconazole, itraconazole). There is some evidence that combined use of flucytosine and amphotericin B may be associated with an increased risk of serious adverse effects, especially in immunocompromised patients including those with human immunodeficiency virus (HIV) infection.
