Comparative pharmacokinetics of cephalexin, cefaclor, cefadroxil, and CGP 9000.
In a randomized crossover study, the pharmacokinetics of three new cephalosporin antibiotics, cefaclor, cefadroxil, and CGP 9000, in comparison to cephalexin, were determined after oral administration, by capsules, of 1,000 mg on an empty stomach in 12 normal subjects. Serum concentrations were measured during a period of 8 h, and urine recovery was measured during 24 h. The significant paramet...
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...
متن کاملPharmacokinetics of cefaclor and cephalexin: dosage nomograms for impaired renal function.
The pharmacokinetics of cefaclor and cephalexin were characterized in patients with creatinine clearances ranging from 0 to 147 ml/min. Each of 24 fasted subjects received a single 500-mg oral dose of cefaclor, and 13 of these subjects later received 500 mg of cephalexin. Serum and urine levels of the antibiotics were measured by bioassay. The serum half-lives were highly correlated with correc...
متن کاملCefroxadine (CGP-9000), an orally active cephalosporin.
Cefroxadine (GCP-9000; CXD), 7 beta[D-2-amino-2-(1,4-cyclohexadienyl)-acetamido]-3-methoxy-ceph-3-em-carboxylic acid, is a new orally active cephalosporin derivative. The spectrum of antibacterial activity of CXD is identical with that of cephalexin (CEX), but CXD was twofold more effective than CEX against Escherichia coli and Klebsiella pneumoniae, CXD was as stable to penicillinase as CEX, b...
