Ceftazidime is a semisynthetic, broad-spectrum, beta-lactam antibiotic, used especially for Pseudomonas and other gram-negative infections in debilitated patients. Ceftazidime is used to treat lower respiratory tract, skin, urinary tract, blood-stream, joint, and abdominal infections, and meningitis. The drug is given intravenously (IV) or intramuscularly (IM) every 8–12 hours (two or three times a day), with dose and frequency varying by the type of infection, severity, and/or renal function of the patient. Injectable formulations of ceftazidime are currently nebulized "off-label" to manage Cystic Fibrosis, non-Cystic Fibrosis bronchiectasis, drug-resistant nontuberculous mycobacterial infections, ventilator-associated pneumonia, and post-transplant airway infections. Ceftazidime is generally well-tolerated. When side effects do occur, they are most commonly local effects from the intravenous line site, allergic reactions, and gastrointestinal symptoms. According to one manufacturer, in clinical trials, allergic reactions including itching, rash, and fever, happened in fewer than 2% of patients. Rare but more serious allergic reactions, such as toxic epidermal necrolysis, Stevens-Johnson syndrome, and erythema multiforme, have been reported with this class of antibiotics, including ceftazidime. Gastrointestinal symptoms, including diarrhea, nausea, vomiting, and abdominal pain, were reported in fewer than 2% of patients.

Central Nervous System Infections, including meningitis, caused by Haemophilus influenzae and Neisseria meningitidis. Ceftazidime for injection, USP has also been used successfully in a limited number of cases of meningitis due to Pseudomonas aeruginosa and Streptococcus pneumoniae. Ceftazidime for injection, USP may be used alone in cases of confirmed or suspected sepsis. Ceftazidime for injection, USP has been used successfully in clinical trials as empiric therapy in cases where various concomitant therapies with other antibiotics have been used. Ceftazidime for injection, USP may also be used concomitantly with other antibiotics, such as aminoglycosides, vancomycin, and clindamycin; in severe and life-threatening infections; and in the immunocompromised patient. When such concomitant treatment is appropriate, prescribing information in the labeling for the other antibiotics should be followed. The dose depends on the severity of the infection and the patient's condition. To reduce the development of drug-resistant bacteria and maintain the effectiveness of ceftazidime for injection, USP and other antibacterial drugs, ceftazidime for injection, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Launch Date 4.90579198E11

Sample Use Guides

In Vivo Use Guide

The usual adult dosage is 1 gram administered intravenously or intramuscularly every 8 to 12 hours. The dosage and route should be determined by the susceptibility of the causative organisms, the severity of infection, and the condition and renal function of the patient.

In Vitro Use Guide

Ceftazidime–avibactam and comparator antibacterial agents were tested by reference broth microdilution against 417non-repetitive Gram-negative bacilli (387 unselected, plus 30selected blaKPC-positive, meropenem – nonsusceptible, Kleb-siella pneumoniae) collected prospectively from medical centersat Hospital das Clínicas da Faculdade de Medicina da Uni-versidade de São Paulo, Brazil, in 2014 and 2015. Minimum inhibitory concentrations (MICs), one per isolate, were determined by reference Clinical and Laboratory Standards Institute (CLSI) broth microdilution methods using frozen microtiter plates pre-loaded with antibiotic-containing growth medium. MICs ofceftazidime–avibactam were measured by varying the concen-tration of ceftazidime in twofold increments with avibactamat a fixed concentration of 4 mg/L. Addition of avibactam at 4 mg/L decreased MICs of cef-tazidime against unselected Enterobacteriaceae, especially K.pneumoniae, Citrobacter freundii, and Enterobacter cloacae, among which MIC90values decreased from 128 to >128 mg/L to0.5–4 mg/L. Among the unselected isolates of these three species 37–73% were susceptible to ceftazidime, whereas 100%were susceptible to ceftazidime–avibactam.
