Comparison of in vitro activity of cephalexin, cephradine, and cefaclor.
Inhibitory activity of cephalexin, cephradine, and cefaclor was compared by the WHO-ICS agar dilution technique. Cefaclor was substantially more active against staphylococci, streptococci, gonococci, meningococci, Haemophilus, Escherichia coli, Klebsiella pneumoniae, Citrobacter diversus, Proteus mirabilis, salmonellae, and shigellae than was cephalexin, which in turn was more active than cephr...
متن کاملThe Fluorometric Determination of Riboflavin in Urine and Other Biological Fluids
The increasing frequency with which riboflavin deficiency is being discovered in man has given an impetus to the study of this substance in biological fluids wi’ith a view to providing a quick and accurate diagnost,ic method. For this purpose chemical methods of determination are distinctly to be preferred to the more laborious and time-consuming biological and microbiological methods. Several ...
متن کاملThe determination of cephradine and cephalexin by reverse phase high-performance liquid chromatography.
The application of reverse phase high-performance liquid chromatography to the separation and analysis of cephradine and cephalexin is demonstrated. The procedure has been applied to chemicals, pharmaceutical formulations and reaction solutions. The preparation of samples is simple and rapid. Chromatographic conditions are described for both pellicular and small particle columns. The feasibilit...
متن کاملComparative human oral clinical pharmacology of cefadroxil, cephalexin, and cephradine.
At equivalent oral doses, cefadroxil has a longer serum half-life, slower urinary excretion rate, greater area under the serum level versus time curve than cephalexin or cephradine, and peak serum concentrations that are 75 to 80% those of cephalexin. The calculated, apparent in vivo volume of distribution of cefadroxil is greater than that of cephalexin. These properties infer greater persiste...
متن کاملLiquid-chromatographic determination of five orally active cephalosporins--cefixime, cefaclor, cefadroxil, cephalexin, and cephradine--in human serum.
We report an isocratic "high-performance" liquid-chromatographic (HPLC) procedure for measurement of five orally administered cephalosporins (cefixime, cefaclor, cefadroxil, cephalexin, and cephradine) in 0.1 mL of human serum. Serum protein is precipitated with acetonitrile, the sample is centrifuged, and the supernate is evaporated under nitrogen. The residue is reconstituted in 0.1 mL of mob...
