OBJECTIVE Assessing the stability of cefazolin sodium in preservative-free and preservative-containing eye drops. METHOD Extemporaneous formulations of eye drops were prepared from a commercially-available parenteral product of cefazolin sodium: eye drops 'A' contained 50mg/ml of cefazolin sodium in 0.45% w/v sodium chloride solution, and eye drops 'B' contained 50 mg/ml, 0.005% w/v thiomersa...

BACKGROUND A prospective, single center, open-label study was conducted to determine if the standard practice for surgical prophylaxis, which includes standardized dosing of cefazolin, at the University of Maryland Medical Center (UMMC) is adequate for patients placed on bypass during cardiac surgery. METHODS All patients were given the same standard dosing regimen regardless of weight: two g...

The biliary tract excretion of cefamandole, cefazolin, and cephalothin was measured in eight patients with T-tubes inserted into their common ducts after ductal exploration for biliary tract stones. Each patient received 1.0 g intravenously of each cephalosporin on 3 separate days; T-tube bile and serum were collected at selected time intervals thereafter. In seven patients, bile and urine were...

The nephrotoxicity of ceftazidime compared with that of cefazolin or cephaloridine and the capacity of ceftazidime to enhance the nephrotoxicity of tobramycin were evaluated in rats. Only cephaloridine and tobramycin given alone altered creatinine clearance or caused significant histological injury. Our data suggest that ceftazidime is no more nephrotoxic than cefazolin and does not enhance the...

Cefazolin is commonly administered before surgery as a prophylactic antibiotic. Hypersensitivity to cefazolin is not uncommon, and the symptoms mostly include urticaria, skin reaction, diarrhea, vomiting, and transient neutropenia, which are rarely life threatening. We present a rare case of fatal cefazolin hypersensitivity in a female who was diagnosed with multiple meningiomas and scheduled f...

PURPOSE To compare the efficacy of topical cefazolin-gentamicin versus vancomycinceftazidime for treatment of bacterial corneal ulcers. METHODS This randomized double-masked clinical trial was performed on consecutive patients with bacterial corneal ulcers referred to Feiz Hospital, Isfahan, Iran from 2004 to 2005. Patients were randomly assigned to cefazolin-gentamicin or vancomycin-ceftazid...

Antibiotic prophylaxis with norfloxacin, intravenous ciprofloxacin, or ceftriaxone has been recommended for cirrhotic patients with gastrointestinal hemorrhage but little is known about intravenous cefazolin. This study aimed to compare the outcome of intravenous cefazolin and ceftriaxone as prophylactic antibiotics among cirrhotic patients at different clinical stages, and to identify the asso...

OBJECTIVE The aim of this study was to investigate the stability of fortified cefazolin sodium ophthalmic solutions (50 mg mL⁻¹) extemporaneously prepared in commercial artificial tears containing 2 different types of preservatives, namely the surfactants and oxidants. METHODS Fortified cefazolin sodium solutions were prepared by reconstituting cefazolin for injection with sterile water and f...

Several studies have previously reported synergistic effects between vancomycin and a given b-lactam or a given aminoglycoside against methicillin-resistant Staphylococcus aureus (MRSA) strains. The aim of our study was to exhaustively compare the effects of different combinations of a b-lactam, vancomycin, and/or an aminoglycoside against 32 clinical MRSA strains with different aminoglycoside ...

OBJECTIVES Cefazolin is frequently administered for antimicrobial prophylaxis and treatment of infections. In neonates, pharmacokinetic observations are limited and dosing regimens variable. The aim of this study was to describe the pharmacokinetics of cefazolin in neonates based on total and unbound concentrations to optimize cefazolin dosing. METHODS Thirty-six neonates [median birth body w...
