Mechanism of Action

Ceftazidime is a semisynthetic, broad-spectrum, beta-lactam antibiotic for parenteral administration. Ceftazidime is bactericidal in action exerting its effect by inhibition of enzymes responsible for cell-wall synthesis. A wide range of gram-negative organisms is susceptible to ceftazidime in vitro, including strains resistant to gentamicin and other aminoglycosides. In addition, ceftazidime has been shown to be active against gram-positive organisms. It is highly stable to most clinically important beta-lactamases, plasmid or chromosomal, which are produced by both gram-negative and gram-positive organisms and, consequently, is active against many strains resistant to ampicillin and other cephalosporins.

Contraindications

Ceftazidime is contraindicated in patients who have shown hypersensitivity to Ceftazidime or the cephalosporin group of antibiotics.

Side Effects

The most common side-effects are local reactions following IV injection and allergic and gastrointestinal reactions. Hypersensitivity reactions are pruritus, rash, and fever. Angioedema and anaphylaxis have been reported very rarely. Gastrointestinal symptoms are diarrhea, nausea, vomiting, and abdominal pain. Central nervous system reactions included headache, dizziness, and paresthesia.

Pregnancy and Lactation

Pregnancy: No adequate and well-controlled studies in pregnant women have been conducted with Ceftazidime. Because animal reproduction studies are not always predictive of human response this drug should be used during pregnancy only if clearly needed.Lactation: Ceftazidime is excreted in human milk in low concentrations. Because many drugs are excreted in human milk and because the safety of the component of the injections in nursing infants has not been established, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Precautions and Warnings

The total daily dosage should be reduced when Cefazid is administered to patients with renal insufficiency. Cefazid should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis.

Use in Special Populations

Impaired Renal Function: Cefazid is excreted by the kidneys, almost exclusively by glomerular filtration. Therefore, in patients with impaired renal function (glomerular filtration rate <50 mL/min), it is recommended that the dosage of ceftazidime be reduced to compensate for its slower excretion. In patients with suspected renal insufficiency, an initial loading dose of 1 gram of Cefazid may be given. An estimate of GFR should be made to determine the appropriate maintenance dosage.Dosage in peritoneal dialysis: Cefazid may also be used in peritoneal dialysis and continuous ambulatory peritoneal dialysis (CAPD). As well as using Cefazid intravenously, it can be incorporated into the dialysis fluid (usually 125 to 250 mg for 2L of dialysis fluid).Impaired Hepatic Function: No adjustment in dosage is required for patients with hepatic dysfunction.

Overdose

Cefazid overdosage has occurred in patients with renal failure. Reactions have included seizure activity, encephalopathy, asterixis, neuromuscular excitability, and coma. Patients who receive an acute overdosage should be carefully observed and given supportive treatment.

Storage

Store below 25°C, protected from light and moisture. Reconstituted solutions are stable for up to 24 h if stored between 2°-8°C.
