Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested. Pharmacokinetics (Adult data unless noted) Distribution: Widely throughout the body including bone, bile, skin, CSF (higher concentrations achieved when meninges are inflamed), endometrium, heart, pleural and lymphatic fluids Protein binding: 17% Half-life elimination: 1-2 hours, prolonged with renal impairment; Neonates <23 days: 2.2-4.7 hours Time to peak, serum: I.M.: ~1 hour Excretion: Urine (80% to 90% as unchanged drug) Indications & Usage Use Treatment of documented susceptible Pseudomonas aeruginosa infection and infections due to other susceptible aerobic gram-negative organisms; empiric therapy of a febrile, granulocytopenic patient Use: Unlabeled/Investigational Bacterial endophthalmitis Contraindications Hypersensitivity to ceftazidime, any component of the formulation, or other cephalosporins Warnings/Precautions Concerns related to adverse effects: • Elevated INR: May be associated with increased INR, especially in nutritionally-deficient patients, prolonged treatment, hepatic or renal disease. • Penicillin allergy: Use with caution in patients with a history of penicillin allergy, especially IgE-mediated reactions (eg, anaphylaxis, angioedema, urticaria). • Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment. Disease-related concerns: • Renal impairment: Use with caution in patients with renal impairment; modify dosage in severe impairment. • Seizure disorders: Use with caution in patients with a history of seizure disorder; high levels, particularly in the presence of renal impairment, may increase risk of seizures. Pregnancy & Lactation Pregnancy Risk Factor B Pregnancy Implications Teratogenic effects were not observed in animal reproduction studies. Ceftazidime crosses the placenta and reaches the cord serum and amniotic fluid. An increase in most types of birth defects was not found following first trimester exposure to cephalosporins. Maternal peak serum concentration is unchanged in the first trimester. After the first trimester, serum concentrations decrease by approximately 50% of those in nonpregnant patients. Renal clearance is increased during pregnancy. Lactation Enters breast milk/use caution (AAP rates “compatible”; AAP 2001 update pending) Adverse Reactions 1% to 10%: Gastrointestinal: Diarrhea (1%) Local: Pain at injection site (1%) Miscellaneous: Hypersensitivity reactions (2%) <1%: Anaphylaxis, angioedema, asterixis, BUN increased, candidiasis, creatinine increased, dizziness, encephalopathy, eosinophilia, erythema multiforme, fever, headache, hemolytic anemia, hyperbilirubinemia, jaundice, leukopenia, myoclonus, nausea, neuromuscular excitability, paresthesia, phlebitis, pruritus, pseudomembranous colitis, rash, Stevens-Johnson syndrome, thrombocytosis, toxic epidermal necrolysis, transaminases increased, vaginitis, vomiting Reactions reported with other cephalosporins: Seizure, urticaria, serum-sickness reactions, renal dysfunction, interstitial nephritis, toxic nephropathy, elevated BUN, elevated creatinine, cholestasis, aplastic anemia, hemolytic anemia, pancytopenia, agranulocytosis, colitis, prolonged PT, hemorrhage, superinfection Interactions Drug Interactions: Metabolism/Transport Effects None known. Drug Interactions Aminoglycosides: Cephalosporins (3rd Generation) may enhance the nephrotoxic effect of Aminoglycosides. Risk C: Monitor therapy BCG: Antibiotics may diminish the therapeutic effect of BCG. Risk X: Avoid combination Probenecid: May increase the serum concentration of Cephalosporins. Risk C: Monitor therapy Sodium Picosulfate: Antibiotics may diminish the therapeutic effect of Sodium Picosulfate. Management: Consider using an alternative product for bowel cleansing prior to a colonoscopy in patients who have recently used or are concurrently using an antibiotic. Risk D: Consider therapy modification Typhoid Vaccine: Antibiotics may diminish the therapeutic effect of Typhoid Vaccine. Only the live attenuated Ty21a strain is affected. Management: Vaccination with live attenuated typhoid vaccine (Ty21a) should be avoided in patients being treated with systemic antibacterial agents. Use of this vaccine should be postponed until at least 24 hours after cessation of antibacterial agents. Risk D: Consider therapy modification Vitamin K Antagonists (eg, warfarin): Cephalosporins may enhance the anticoagulant effect of Vitamin K Antagonists. Risk C: Monitor therapy Lab Test Interactions Positive direct Coombs', false-positive urinary glucose test using cupric sulfate (Benedict's solution, Clinitest®, Fehling's solution), falsepositive serum or urine creatinine with Jaffé reaction Dosing Dosing: Adults Bacterial arthritis (gram negative bacilli): I.V.: 1-2 g every 8 hours Bone and joint infections: I.V.: 2 g every 12 hours Cystic fibrosis, lung infection caused by Pseudomonasspp: I.V.: 30-50 mg/kg/dose every 8 hours (maximum: 6 g daily) Endophthalmitis, bacterial (unlabeled use): Intravitreal: 2.25 mg/0.1 mL NS in combination with vancomycin Intra-abdominal infection, severe (in combination with metronidazole): I.V.: 2 g every 8 hours for 4-7 days (provided source controlled). Not recommended for hospital-acquired intra-abdominal infections (IAI) associated with multidrug-resistant gram negative organisms or in mild-to-moderate community-acquired IAIs due to risk of toxicity and the development of resistant organisms (Solomkin, 2010). Melioidosis: I.V.: 40 mg/kg/dose every 8 hours for 10 days, followed by oral therapy with doxycycline or TMP/SMX Otitis externa: I.V.: 2 g every 8 hours Peritonitis (CAPD): Anuric, intermittent: 1-1.5 g daily Anuric, continuous (per liter exchange): Loading dose: 250 mg; maintenance dose: 125 mg Pneumonia: I.V.: Uncomplicated: 500 mg to 1 g every 8 hours Complicated or severe: 2 g every 8 hours Prosthetic joint infection,Pseudomonas aeruginosa(alternative to cefepime or meropenem): I.V.: 2 g every 8 hours for 4-6 weeks (consider addition of an aminoglycoside) (Osmon, 2013) Skin and soft tissue infections: I.V., I.M.: 500 mg to 1 g every 8 hours Severe infections, including meningitis, complicated pneumonia, endophthalmitis, CNS infection, osteomyelitis, gynecological, skin and soft tissue: I.V.: 2 g every 8 hours Urinary tract infections: I.V., I.M.: Uncomplicated: 250 mg every 12 hours Complicated: 500 mg every 8-12 hours Dosing: Elderly I.M., I.V.: Dosage should be based on renal function with a dosing interval not more frequent then every 12 hours. Dosing: Pediatric Susceptible infections: I.V.: Children 1 month to 12 years: 30-50 mg/kg/dose every 8 hours; maximum dose: 6 g/day (higher doses reserved for immunocompromised patients, cystic fibrosis, or meningitis) Children ≥12 years: Refer to adult dosing. Dosing: Renal Impairment Clcr 30-50 mL/minute: Administer every 12 hours Clcr 10-30 mL/minute: Administer every 24 hours Clcr <10 mL/minute: Administer every 48-72 hours Intermittent hemodialysis (IHD) (administer after hemodialysis on dialysis days): Dialyzable (50% to 100%): 500 mg to 1 g every 24 hours or 1-2 g every 48-72 hours (Heintz, 2009). Note: Dosing dependent on the assumption of 3 times per week, complete IHD sessions. Peritoneal dialysis (PD): Loading dose of 1 g, followed by 500 mg every 24 hours Continuous renal replacement therapy (CRRT) (Heintz, 2009; Trotman, 2005): Drug clearance is highly dependent on the method of renal replacement, filter type, and flow rate. Appropriate dosing requires close monitoring of pharmacologic response, signs of adverse reactions due to drug accumulation, as well as drug concentrations in relation to target trough (if appropriate). The following are general recommendations only (based on dialysate flow/ultrafiltration rates of 1-2 L/hour and minimal residual renal function) and should not supersede clinical judgment: CVVH: Loading dose of 2 g followed by 1-2 g every 12 hours CVVHD/CVVHDF: Loading dose of 2 g followed by either 1 g every 8 hours or 2 g every 12 hours. Note: Dosage of 1 g every 8 hours results in similar steady-state concentrations as 2 g every 12 hours and is more cost effective. Dosage of 2 g every 8 hours may be needed for gram-negative rods with MIC ≥4 mg/L (Heintz, 2009). Note: For patients receiving CVVHDF, some recommend giving a loading dose of 2 g followed by 3 g over 24 hours as a continuous I.V. infusion to maintain concentrations ≥4 times the MIC for susceptible pathogens (Heintz, 2009). Dosing: Hepatic Impairment No dosage adjustment necessary. Available Products Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Observe for signs and symptoms of anaphylaxis during first dose. Breast-Feeding Considerations Very small amounts of ceftazidime are excreted in breast milk. The manufacturer recommends that caution be exercised when administering ceftazidime to nursing women. Ceftazidime in not absorbed when given orally; therefore, any medication that is distributed to human milk should not result in systemic concentrations in the nursing infant. Nondose-related effects could include modification of bowel flora. Patient Education Discuss specific use of drug and side effects with patient as it relates to treatment. Patient may experience nausea, diarrhea, or vaginal yeast infection. Have patient report immediately to prescriber ecchymosis or rash. Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions. Dietary Implications Some products may contain sodium.
