ceftazidime for injection, USP
Ceftazidime is a semisynthetic, broad-spectrum, beta-lactam antibiotic for parenteral administration. It is the pentahydrate of pyridinium, 1-[[7-[[(2-amino-4-thiazolyl)[(1-carboxy-1-methyl-ethoxy) imino]acetyl]amino]-2-carboxy-8-oxo-5-thia-1-azabicyclo (4.2. 0.)oct-2-en-3-yl] methyl]-,hydroxide, inner salt, [6R-[6α,7β(Z)]].
Tazicef (ceftazidime for injection, USP) is indicated for the treatment of patients with infections caused by susceptible strains of the designated organisms in the following diseases:
Lower Respiratory Tract Infections, including pneumonia, caused by Pseudomonas aeruginosa and other Pseudomonas spp.; Haemophilus influenzae, including ampicillin-resistant strains; Klebsiella spp.; Enterobacter spp.; Proteus mirabilis; Escherichia coli; Serratia spp.; Citrobacter spp.; Streptococcus pneumoniae; and Staphylococcus aureus (methicillin-susceptible strains).
Skin and Skin-Structure Infections caused by Pseudomonas aeruginosa; Klebsiella spp.; Escherichia coli; Proteus spp.; including Proteus mirabilis and indole-positive Proteus ; Enterobacter spp.; Serratia spp.; Staphylococcus aureus (methicillin-susceptible strains); and Streptococcus pyogenes (group A beta-hemolytic streptococci).
Urinary Tract Infections, both complicated and uncomplicated, caused by Pseudomonas aeruginosa ; Enterobacter spp.; Proteus spp., including Proteus mirabilis and indole-positive Proteus; Klebsiella spp.; and Escherichia coli.
Bacterial Septicemia caused by Pseudomonas aeruginosa, Klebsiella spp., Haemophilus influenzae, Escherichia coli, Serratia spp., Streptococcus pneumoniae, and Staphylococcus aureus (methicillin-susceptible strains).
Bone and Joint Infections caused by Pseudomonas aeruginosa; Klebsiella spp.; Enterobacter spp., and Staphylococcus aureus (methicillin-susceptible strains).
Gynecologic Infections, including endometritis, pelvic cellulitis, and other infections of the female genital tract caused by Escherichia coli.
Intra-abdominal Infections, including peritonitis caused by Escherichia coli, Klebsiella spp., and Staphylococcus aureus (methicillin-susceptible strains) and polymicrobial infections caused by aerobic and anaerobic organisms and Bacteroides spp. (many strains of Bacteroides fragilis are resistant).
Central Nervous System Infections, including meningitis, caused by Haemophilus influenzae and Neisseria meningitidis. Ceftazidime has also been used successfully in a limited number of cases of meningitis due to Pseudomonas aeruginosa and Streptococcus pneumoniae.
Specimens for bacterial cultures should be obtained before therapy in order to isolate and identify causative organisms and to determine their susceptibility to ceftazidime. Therapy may be instituted before results of susceptibility studies are known; however, once these results become available, the antibiotic treatment should be adjusted accordingly.
Tazicef (ceftazidime for injection, USP) may be used alone in cases of confirmed or suspected sepsis. Ceftazidime has been used successfully in clinical trials as empiric therapy in cases where various concomitant therapies with other antibiotics have been used.
Tazicef 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 Tazicef (ceftazidime) and other antibacterial drugs, Tazicef (ceftazidime) 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.
Published Studies Related to Tazicef (Ceftazidime)
Nebulized ceftazidime and amikacin in ventilator-associated pneumonia caused by Pseudomonas aeruginosa. [2011.07.01]
RATIONALE: In experimental pneumonia, nebulization of antibiotics provides high lung tissue concentrations and rapid bacterial killing. OBJECTIVES: To assess the efficacy and safety of nebulized ceftazidime and amikacin in ventilator-associated pneumonia caused by Pseudomonas aeruginosa... CONCLUSIONS: Nebulization and intravenous infusion of ceftazidime and amikacin provide similar efficiency for treating ventilator-associated pneumonia caused by Pseudomonas aeruginosa. Nebulization is efficient against intermediate strains and may prevent per-treatment acquisition of antibiotic resistance.
Continuous vs thrice-daily ceftazidime for elective intravenous antipseudomonal therapy in cystic fibrosis. [2009.10]
BACKGROUND/AIM: We hypothesized that a continuous 24-h infusion of 100 mg/kg per day ceftazidime (treatment C) would result in equivalent or even superior anti-infectious efficacy in chronic Pseudomonus aeruginosa (PA) infection in patients with cystic fibrosis (CF) in comparison to the usual application of 200 mg/kg per day ceftazidime in three doses (treatment T)... CONCLUSION: We conclude that continuous or thrice-daily dosing of intravenous ceftazidime, both combined with once-daily tobramycin, are equally effective application regimens for elective antipseudomonal therapy in clinically stable patients with CF.
Piperacillin/tazobactam plus ceftazidime versus sulbactam/ampicillin plus aztreonam as empirical therapy for fever in severely neutropenic pediatric patients. [2009.04]
CONCLUSIONS: PIPC/TAZ+CAZ and SBT/ABPC+AZT are effective and safe for initial empirical treatment of febrile episodes in neutropenic pediatric patients. The clinical efficacy of SBT/ABPC+AZT is equivalent or superior to that of PIPC/TAZ+CAZ, the effect of which is already proven against febrile neutropenia. Therefore, SBT/ABPC+AZT may be a treatment of choice for febrile neutropenia in pediatric cancer patients.
A randomized, double-blind trial comparing ceftobiprole medocaril with vancomycin plus ceftazidime for the treatment of patients with complicated skin and skin-structure infections. [2008.03.01]
BACKGROUND: A randomized, double-blind, multicenter trial involving patients with a broad range of complicated skin and skin-structure infections due to either gram-positive or gram-negative bacteria was conducted to compare ceftobiprole monotherapy with treatment with vancomycin plus ceftazidime... CONCLUSIONS: Ceftobiprole monotherapy is as effective as vancomycin plus ceftazidime for treating patients with a broad range of complicated skin and skin-structure infections and infections due to gram-positive and gram-negative bacteria.
Piperacillin/tazobactam vs ceftazidime in the treatment of neutropenic fever in patients with acute leukemia or following autologous peripheral blood stem cell transplantation: a prospective randomized trial. [2006.02]
Piperacillin/tazobactam was compared with ceftazidime for the empirical treatment of febrile neutropenia in patients with acute leukemia or following autologous peripheral blood stem cell transplantation. Owing to inclusion criteria, it was possible for the same patient to be randomized several times.

A Study to Assess the Levels of Two Antibiotics in the Blood When Given Together and Separately [Completed]
This is a randomised study divided into 2 parts. Part A investigates the effect of
prolonged dosing (ten days) with Avibactam and Ceftazidime when given together and how this
will effect how much Avibactam and Ceftazidime enters the blood. Part B investigates how
much Avibactam (NXL104) and Ceftazidime enter the blood when Avibactam and Ceftazidine are
given separately or together intravenously.
