Mechanisms of action of 5-fluorocytosine.
5-Fluorouracil and 5-fluorodeoxyuridine monophosphate levels were estimated in 75 isolates of Candida albicans to determine whether 5-fluorocytosine susceptibility could be ideally correlated with the intrafungal formation of both 5-fluorodeoxyuridine monophosphate and 5-fluorouridine triphosphate or a reciprocal formation of the two metabolites to prove the mechanism of 5-fluorocytosine activi...
متن کاملOcular penetration of 5-fluorocytosine.
Ocular penetration of 5-fluorocytosine (5FC) was studied in uninfected rabbits after subconjunctival and oral administration. With oral administration, 5FC achieved therapeutic levels in both the vitreous and aqueous humors. The use of a pharmacokinetic model permitted objective comparison of kinetic events within the eye chambers and the serum. The rates of entry and elimination in the vitreou...
متن کامل5-fluorocytosine and urinary candidiasis.
Two patients with urinary candidiasis were treated with 5-fluorocytosine. Serum levels of the drug and a study of its excretion in urine are recorded together with a brief account of its activity in body fluids. Evidence of toxicity was not observed with dosages of from 2 to 5 g a day.
متن کاملPharmacological studies with 5-fluorocytosine.
A cylinder plate bioassay for 5-fluorocytosine (5-FC) is described which permits determination of 5-FC concentrations in biological fluids in the presence of amphotericin B. Using this assay, we determined serum concentrations in 12 patients after a single dose of drug and in 8 patients receiving daily 5-FC at 6-hr intervals (4 to 120 days). Drug was detectable in serum as early as 0.5 hr and c...
متن کاملThe antimycotic activity of 5-fluorocytosine.
5-Fluorocytosine (5 FC) showed marked in vitro activity against nearly all the clinical isolates of Candida and Cryptococcus examined; the required minimal inhibitory concentration was usually below 2 mug/ml and the minimal cidal concentration below 10 mug/ml. The drug had limited activity towards Aspergillus species and dermatophytes. Strains of Candida and other fungi with greatly enhanced re...
