TO THE EDITOR: Piritramide (1-(3-cyano-3,3-diphenyl-propyl)-4-(1piperidyl)piperidine-4-carboxamide) is a commonly used opioid for postoperative pain treatment in Germany.1 Cephalosporins such as cefuroxime or cefazolin are commonly administered as prophylactic antibiotic therapy for surgical procedures.2 Thus, simultaneous use of piritramide and antibiotics might occur often in a perioperative ...
Blood levels of cefazolin and cephalothin were determined in two separate crossover studies in 20 healthy male adults, each after intravenous and intramuscular administration. Pharmacokinetic parameters were calculated from the intravenous data based upon a two-compartment open model. The rate constants controlling the distribution between the central and peripheral compartments, the overall el...
The in vitro susceptibility of 155 strains of anaerobic bacteria to five cephalosporin antibiotics was tested. Cefoxitin was the most active against 33 isolates of Bacteroides fragilis; 82% of the strains were sensitive at 16 mug/ml. At 64 mug/ml cefazolin and cephaloridine were also generally effective. Cephalothin and cephalexin were relatively inactive versus B. fragilis. Cefoxitin, cephalor...
Some proportion of type A blaZ gene-positive methicillin-susceptible Staphylococcus aureus strains exhibit the cefazolin inoculum effect (CIE). The type A blaZ gene was divided into two groups by single nucleotide polymorphisms (SNPs) at Ser226Pro and Cys229Tyr. The median cefazolin MICs at a high inoculum concentration were 5.69 μg/ml for the Ser-Cys group and 40.32 μg/ml for the Pro-Tyr group...
The rapid fixed-time assay for penicillinase was modified for measuring beta-lactamase activity with twelve substrates, i.e., benzylpenicillin, ampicillin, cloxacillin, methicillin, carbenicillin, cefazolin, cephalothin, cephaloglycin, cephalexin, cephalosporin C, 7-aminocephalosporanic acid, and cefoxitin. The method depends upon the reduction of iodine by the hydrolyzed substrate. Determined ...
The Autoturb System, a semiautomated system for photometric bioassay, was used to determine cefazolin content. Suitable conditions for the assay using Streptococcus faecalis ATCC 10541 as the indicator organism included a medium pH of 6.0 to 7.0 and an incubation time of 3 to 3.5 h at 36 C. Multiple independent assays of samples from a common batch showed the test to be highly reproducible. Acc...
