| pubmed-article:3693588 | pubmed:abstractText | The tolerance to and pharmacokinetics of cefixime, a new oral cephalosporin, were evaluated in healthy volunteers given the drug in single doses of 50, 100 and 200 mg and repeated doses of 200 mg bid for 14 days. In the repeated-dose study, there were mild and transient subjective symptoms such as soft stools, diarrhea, and anorexia, which disappeared without additional treatment during the dosing period. Slight increases in eosinophil and serum amylase levels were also observed. The serum concentrations of cefixime peaked at 0.71, 1.17, and 2.08 micrograms/mL on average, four to five hours after dosing with 50, 100, and 200 mg, respectively, and the half-lives were 2.54, 2.38, and 2.29 hours. Serum concentrations and urinary recoveries after dosing with 100 mg were little affected by food ingestion. There was no evidence of cefixime accumulation in the body by repeated dosing since mean serum concentrations and urinary recoveries were almost the same on the first, third, seventh, and 14th days of dosing. | lld:pubmed |
