5-fluorocytosine and amphotericin B in bronchial secretions.
The penetration into and clearance from bronchial secretions of 5-fluorocytosine and amphotericin B were studied in a dog model. After a single intravenous dose of 35 mg/kg, 5-fluorocytosine intrabronchial concentrations were greater than the minimal inhibitory concentration for 80 to 90% of Candida species. These inhibitory concentrations persisted up to 3 h. In contrast, amphotericin B in int...
متن کاملIn Vivo Susceptibility of Cryptococcus neoformans to Hamycin, Amphotericin B, and 5-Fluorocytosine.
Previous investigations have shown that hamycin is 5 to 10 times more active in vitro than amphotericin B against Cryptococcus neoformans, whereas 5-fluorocytosine is approximately 15 times less active. Present studies are concerned with a comparison of these drugs in vivo. Three strains of C. neoformans which varied in both their virulence for mice and their susceptibilities to the antifungal ...
متن کاملIn vitro studies with combinations of 5-fluorocytosine and amphotericin B.
Synergistic antifungal activity of 5-fluorocytosine (5-FC) and amphotericin B was studied using an abbreviated checkerboard titration scheme. 5-FC was titrated in twofold increments (100 to 0.05 mug/ml) in the absence and presence of graded increments of amphotericin B (1.0. 0.5, 0.1, 0.05, and 0.01 mug/ml) in buffered yeast nitrogen base. A limited number of experiments were performed using ex...
متن کاملChemotherapeutic activity of 5-fluorocytosine and amphotericin B against Candida albicans in mice.
The effect of treatment with combinations of the two antifungal agents, 5-fluorocytosine (5-FC) and amphotericin B (AB), against systemic Candida albicans infections in mice was investigated. Graded doses of the single substances and of combinations of the drugs were administered daily for 21 days. The 50% curative dose (CD(50)) values were calculated on the basis of the presence or absence of ...
متن کاملAmphotericin B and 5-fluorocytosine: in vitro effects on lymphocyte function.
The effects of amphotericin B, 5-fluorocytosine, and the combination of both drugs on lymphocyte function in vitro were investigated. Amphotericin B, alone or in combination with 5-fluorocytosine, significantly suppressed both spontaneous lymphocyte transformation and the response of lymphocytes to stimulation with streptokinase-streptodornase. 5-Fluorocytosine had no effect on spontaneous or a...
