Contra Indications

Known serious hypersensitivity to avibactam, ceftazidime, or other cephalosporins

Precautions

Serious and occasionally fatal anaphylactic reactions and serious skin reactions have been reported with beta-lactam antibacterials; caution in patients with history of allergy to cephalosporins, penicillins, or carbapenems Clostridium difficile associated diarrhea (CDAD) has been associated with nearly all systemic antibacterials; severity may range from mild diarrhea to fatal colitis; may occur >2 months following antibacterial use; if CDAD suspected, manage fluid and electrolytes levels and monitor antibacterial treatment for CDAD Seizures, nonconvulsive status epilepticus, encephalopathy, coma, asterixis, neuromuscular excitability, and myoclonia have been reported with ceftazidime, especially in the setting of renal impairment; adjust dose according to CrCl (see Dosage Modifications) Lactation Ceftazidime is excreted in human milk in low concentrations Unknown whether avibactam is excreted into human milk, although avibactam was shown to be excreted in the milk of rats No information is available on the effects of ceftazidime and avibactam on the breastfed child or on milk production

Pregnancy-Lactation

Pregnancy There are no adequate and well-controlled studies of ceftazidime/avibactam, ceftazidime, or avibactam in pregnant women Neither ceftazidime nor avibactam were teratogenic in rats at doses 40 and 9 times the recommended human clinical dose; in the rabbit, at twice the exposure as seen at the human clinical dose, there were no effects on embryofetal development with avibactam Because animal reproduction studies are not always predictive of human response, this drug should be used in pregnancy only if clearly needed Lactation Ceftazidime is excreted in human milk in low concentrations Unknown whether avibactam is excreted into human milk, although avibactam was shown to be excreted in the milk of rats No information is available on the effects of ceftazidime and avibactam on the breastfed child or on milk production

Interactions

Side Effects

Side effects of Ceftazidime + Avibactam : 1-10% (in cIAI plus metronidazole) Diarrhea (8%) Nausea (7%) Vomiting (5%) Headache (3%) Dizziness (2%) Abdominal pain (1%) 1-10% (in cUTI) Diarrhea (3%) Nausea (3%) Constipation (2%) Upper abdominal pain (1%) 1-10% (in HABP/VABP) Nausea (3%) Pruritus (2%) Frequency Not Reported Blood and lymphatic disorders: Thrombocytopenia, thrombocytosis, leukopenia General disorders and administration site conditions: Injection site phlebitis Infections and infestations: Candidiasis Investigations:Increased aspartate aminotransferase, increased alanine aminotransferase, increased gamma-glutamyltransferase Metabolism and nutrition disorders: Hypokalemia Nervous system disorders: Dysgeusia Renal and urinary disorders: Acute kidney injury, renal impairment, nephrolithiasis Skin and subcutaneous tissue disorders: Rash, rash maculopapular, urticaria Psychiatric disorders: Anxiety

Mode of Action

Ceftazidime: Third-generation cephalosporin with broad-spectrum gram-negative activity, including Pseudomonas; arrests bacterial growth by binding to 1 or more penicillin-binding proteins, and thereby inhibiting final transpeptidation step of peptidoglycan synthesis in bacterial cell-wall synthesis and inhibiting cell-wall biosynthesis Avibactam: Diazabicyclooctanone, non-beta-lactam, beta-lactamase inhibitor; alone has no antibacterial activity at clinically relevant doses; when combined with ceftazidime, avibactam protects ceftazidime from degradation by beta-lactamase enzymes and effectively extends the antibiotic spectrum of ceftazidime to include many gram-negative bacteria normally not susceptible to ceftazidime
