Description

Cefazolin is a semisynthetic cephalosporin analog with broad-spectrum antibiotic action due to inhibition of bacterial cell wall synthesis. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, cefazolin inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins. Cefazolin is used to treat bacterial infections of the skin, moderately severe bacterial infections involving the lung, bone, joint, stomach, blood, and urinary tract. It is clinically effective against infections caused by staphylococci and streptococci species of Gram positive bacteria. This drug also can be used for perioperative prophylaxis.

Sample Use Guides

In Vivo Use Guide
Moderate to severe infections: 500 mg to 1 gram, every 6 to 8 hours; mild infections caused by susceptible gram-positive cocci: 250 mg to 500 mg, every 8 hours; acute, uncomplicated urinary tract infections: 1 gram, every 12 hours; Pneumococcal pneumonia: 500 mg, every 12 hours; Severe, life threatening infections (e.g., endocarditis, septicemia): 1 gram to 1.5 grams, every 6 hours
Route of Administration: Other
In Vitro Use Guide
Susceptibilities of 259 isolates of pathogenic bacteria to cefazolin were measured by broth and agar dilution procedures. Beta-hemolytic streptococci were inhibited by 0.25 mug/ml, whereas Staphylococcus aureus and alphahemolytic streptococci were inhibited by 2.0 mug/ml. Enterococci were resistant to less than 32 mug/ml. Wide variation was seen with gram-negative species. Most isolates of Klebsiella species and Proteus mirabilis were inhibited by 4.0 or 8.0 mug/ml. Escherichia coli were less susceptible, and most isolates of Pseudomonas aeruginosa, Serratia species, and Enterobacter species were resistant to 128 mug/ml.
