MATERIAL AND
METHOD: The present study was performed in 24 Thai healthy male volunteers who were intramuscularly injected a single dose of 1.5 g cefoperazone and sulbactam. A single dose, two periods, two sequences, double blind randomized crossover with a one-week washout period was used. Blood samples were collected before and at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, and 12 hours after intramuscular injection and determined for cefoperazone and sulbactam plasma concentration by validated HPLC-UV methods. The pharmacokinetic parameters were analyzed by noncompartmental analysis and the ANOVA was carried out.
RESULTS: Tax of both cefoperazone and sulbactam for volunteers who were injected with either Cefper or Sulperazon injection were not significantly different (p > 0.05). The 90% confidence intervals of the log of ratio of either C(max) or AUC(last) or AUC(inf) of both cefoperazone and sulbactam between 1.5 g Cefper and Sulperazon injections were within the bioequivalence range of 0.80-1.25.
CONCLUSION: The 1.5 g cefoperazone and sulbactam injection of Cefper and Sulperazone used in the present study are bioequivalent. | | Language | eng | | Pub Type(s) | Journal Article
