How is cefazolin metabolized?
Not metabolized. Cefazolin is present in very low concentrations in the milk of nursing mothers. Cefazolin is excreted unchanged in the urine. In the first six hours approximately 60% of the drug is excreted in the urine and this increases to 70%-80% within 24 hours.
What is cefazolin made from?
Cefazolin is a first-generation cephalosporin compound having [(5-methyl-1,3,4-thiadiazol-2-yl)sulfanyl]methyl and (1H-tetrazol-1-ylacetyl)amino side-groups at positions 3 and 7 respectively.
How do you make cefazolin?
Dilute the reconstituted 500 mg, 1 g or 2g of Cefazolin-AFT in a minimum of 10 mL of Sterile Water for Injection. Inject solution slowly over a period of 3 to 5 minutes. Do not inject in less than 3 minutes.
What is the mechanism of action of cefazolin?
Mechanism of action Cefazolin inhibits cell wall biosynthesis by binding penicillin-binding proteins which stops peptidoglycan synthesis. Penicillin-binding proteins are bacterial proteins that help to catalyze the last stages of peptidoglycan synthesis, which is needed to maintain the cell wall.
Is cefazolin nephrotoxic?
Cefazolin, which is nephrotoxic in animals, has not been reported to produce nephrotoxicity in humans. Two studies have documented nephrotoxicity due to ceftazidime, especially in patients with preexisting renal impairment.
Who makes cefazolin?
Cefazolin – Brand names and Manufacturer. Brand names/Manufacturer: ANCEF (SmithKline Beecham – USA, CANADA, ) AREUZOLIN (Areu – SPAIN)
What is the half life of cefazolin?
The mean half-life of cefazolin in the serum was 2 h, whereas that of cephaloridine was 1.4 h.
Is cefazolin bactericidal or bacteriostatic?
The in vitro bactericidal activity of cefazolin was found to be similar to that of cephaloridine and cephalothin but slightly greater than that of cephalexin against a majority of 233 strains of gram-positive and gram-negative organisms.
Is cephalexin and cefazolin the same?
Keflex (cephalexin) Ancef (cefazolin) is only available as an injectable, so it is usually only used in the hospital. It’s good for treating many bacterial infections. Treats bacterial infections. Keflex (cephalexin) is good for treating many bacterial infections, and is available as a generic.
What generation cephalosporin is cefazolin?
First generation cephalosporins include cephalexin and cefazolin. They have good activity against a wide spectrum of Gram-positive bacteria including penicillinase-producing staphylococci.
Which is the most nephrotoxic cephalosporin?
Cephaloridine had the highest nephrotoxic poten- tial while cefazolin showed almost no effect. In the group of second-generation cephalosporins, cefoxitin induced a time-dependent decrease in TEA accumulation and a con- centration-dependent decrease in glucose synthesis by re- nal cortical slices.
Is cefazolin a brand?
Cefazolin is available under the following different brand names: Kefzol and Ancef.
What is the final volume of the 100mg mL cefazolin solution?
For cefazolin 2g, if smaller doses are needed, it is recommended to use half of the reconstituted solution (about 4 mL with 1 g cefazolin; i.e. half of the vial content) and to add a compatible diluent to a final volume of 100 mL (resulting concentration about 10 mg / mL).
What is the half-life of cefazolin?
Why is probenecid with cefazolin?
The once-daily regimen of cefazolin-probenecid is a cheap, practical, and effective treatment option for moderate-to-severe cellulitis, and it avoids the need to use third-generation cephalosporins in most patients.
Can cefazolin cause ATN?
The findings were consistent with AIN caused by cefazolin as the time course of the acute kidney injury coincided with the use of the antibiotic….Table 1.
| Interpretation of ascites fluid | Serum ascites albumin gradient | |
|---|---|---|
| < 1.1 g/dL | ≥ 1.1 g/dL | |
| ≥ 2.5 | Cancer, tuberculosis | Heart failure |
Who manufactures cefazolin?

Is cefazolin compatible with lactated Ringer’s?
Interactions between your drugs No interactions were found between cefazolin and Lactated Ringers Injection.
What is the cefazolin study?
This is a Phase 1, open-label, single-dose, multiple-center, study to determine the pharmacokinetics of a single 3 g dose of cefazolin administered as a 30 minute IV infusion prior to surgery in adult subjects weighing >/= 120 kg. Adult subjects will be enrolled in order to ensure at least 12 subjects complete the study.
What is the target plasma concentration for cefazolin?
In France, the recommended target plasma concentration for cefazolin (given as a continuous infusion or by intermittent administration) is 100% fT>4×MIC for documented infections and 40 to 80 mg/liter (total fraction) for undocumented infections ( 9 ).
How long does it take to administer cefazolin?
Note: In study 0906, cefazolin was administered as a 0.25‐hour infusion, whereas in studies 1202 and 1601 infusion was over 0.5 hours. aSubjects randomized to 2 g intravenous cefazolin via the DUPLEX delivery system only. Model‐Based Simulations
What is the minimum weight needed to safely administer cefazolin to children?
Monte Carlo simulations indicate that a minimal weight cutoff of 50 kg for the administration of a 2‐g cefazolin dose will provide drug exposures in pediatric surgery patients aged 10 to 17 years approximately equivalent to those observed in healthy adults. Conflicts of Interest
