Application

Flucytosine EP Reference standard, intended for use in laboratory tests only as specifically prescribed in the European Pharmacopoeia.

Biochem/physiol Actions

Nucleoside analog that has antifungal activities. 5-FC is deaminated by cytosine deaminase to product 5-fluorouracil, resulting in RNA miscoding. 5-Fluorocytosine inhibits DNA and RNA synthesis and interferes with ribosomal protein synthesis.

Flucytosine is a systemic antifungal drug that is readily absorbed from the gastrointestinal tract. The most clearly documented therapeutic effect has been in cryptococcosis, candidiasis, and chromomycosis. An important limitation of the use of flucytosine in all three diseases has

Flucytosine (5-FC) is a synthetic antimycotic compound, first synthesized in 1957. It has no intrinsic antifungal capacity, but after it has been taken up by susceptible fungal cells, it is converted into 5-fluorouracil (5-FU), which is further converted to metabolites
W L Whelan
Critical reviews in microbiology, 15(1), 45-56 (1987-01-01)
In terms of genetically determined susceptibility to the clinical antifungal agent 5-fluorocytosine (5-FC), Candida albicans may be homozygous sensitive (FCY/FCY), homozygous resistant (fcy/fcy), or heterozygous (fcy/FCY). Although heterozygotes are only slightly resistant, they occur at significant frequency among clinical strains
