Information
| name: | CeftazidimeAndBetaLactamaseInhibitor |
| ATC code: | J01DD52 | route: | intravenous |
| n-compartments | 2 |
Ceftazidime is a third-generation cephalosporin antibiotic combined with a beta-lactamase inhibitor (such as avibactam) to increase effectiveness against resistant Gram-negative bacteria. It is mainly used for the treatment of serious bacterial infections including complicated urinary tract and intra-abdominal infections, and is currently approved for clinical use in many countries.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult volunteers after intravenous administration of ceftazidime/avibactam (2 g/0.5 g).
