The medical need for new antibiotics active against multiply drug-resistant Gram-negative pathogens has been clearly established (5). Organisms of concern include Pseudomonas aeruginosa, as well as extended-spectrum β-lactamase-producing Enterobacteriaceae (5, 10, 13). Unfortunately, the current pipeline for such agents is unimpressive (1, 4, 16, 17).. CXA-101 (previously FR264205) is a broad-spectrum cephalosporin with excellent in vitro and in vivo activity against P. aeruginosa, including drug-resistant isolates (3, 12). In general, the anti-Gram-positive and -Gram-negative profile of CXA-101 is similar to that of third-generation cephalosporins, such as ceftazidime, but its antipseudomonal activity is the most potent among all currently available β-lactams, including the cephalosporins and carbapenems (3). Indeed, the minimum concentration of CXA-101 that inhibits 90% of the microbial strains (MIC90) for P. aeruginosa (≤2 μg/ml) is the lowest among all systemically administered ...
Cefquinome Sulfate (CS) is a fourth-generation cephalosporin, which has been developed solely for veterinary use. It shows potent antibacterial activity against a broad spectrum of bacterial species. However, Cefquinome is susceptible to hydrolysis, which limiting its clinical employment efficacies to some extent. So, in this study, to increase Cefquinome Sulfate biological half-life, a novel Cefquinome Sulfate proliposome was prepared by solid dispersion and effervescent techniques and characterized for morphology, particle size, entrapment efficiency and in vitro release. A Reversed Phase-High Performance Liquid Chromatography (RP-HPLC) method was first chosen and established to determine the drug concentration in plasma after intra muscular (IM) administrating Cefquinome Sulfate solution and liposome at a single dosage of 18 mg/kg in rabbit. Then their pharmacokinetics in vivo was compared. Results showed that the received liposome was milky white suspension, spherical or ellipsoidal in shape. The
High affinity for PBP 2′ is crucial for the antibacterial activity of β-lactams against MRS. Unfortunately, none of the available β-lactam antibiotics sufficiently fulfils this requirement. This fact increasingly limits the therapeutic potential against staphylococcal infections of these otherwise very useful drugs.. However, the intensive search for new antistaphylococcal drugs has shown recently (1, 7, 11, 12, 14) that it is possible to achieve strong inhibition of PBP 2′ with selected β-lactam structures. Ro 63-9141 is a member of the class of pyrrolidinone-3-ylidenemethyl cephems, which show high potency against PBP 2′ of S. aureus but higher IC50s against normal, sensitive PBPs than other β-lactam antibiotics, e.g., methicillin and imipenem. This appears to be a common property of the pyrrolidinone-3-ylidenemethyl cephems, as it has been observed before for other members of this structural class (7). Ro 63-9141 shares features of cephalosporins with 7-aminothiazolylhydroxyimino ...

RESULTS: Among 122 Serratia isolates, 117 (95.9%) were Serratia marcescens and 110 (90.2%) were of nosocomial origin. During the study period, the 122 isolates showed a high rate of resistance to third‐generation cephalosporins (45.9%) and extended‐spectrum penicillins (56.6%). The resistance rate to ciprofloxacin was 32.0%. The resistance rate to third‐generation cephalosporins increased from 31.7% for 1991 to 1995 to 54.9% for 1996 to 1998 and 50.0% for 1999 to 2001. In the multivariate analysis, prior use of a second‐generation cephalosporin (adjusted odds ratio [OR], 5.90; 95% confidence interval [CI95], 1.41 to 24.6; P = .015) or a third‐generation cephalosporin (OR, 3.26; CI95, 1.20 to 8.87; P = .020) was a strong independent risk factor for resistance to third‐generation cephalosporins. The overall case‐fatality rate was 25.4% (Serratia bacteremia-related case‐fatality rate, 13.1 ...
A 10% cross-reactivity rate is commonly cited between penicillins and cephalosporins. However, this figure originated from studies in the 1960s and 1970s which included first-generation cephalosporins with similar side-chains to penicillins. Cephalosporins were frequently contaminated by trace amount of penicillins at that time. The side-chain hypothesis for beta-lactam hypersensitivity is supported by abundant scientific evidence. Newer generations of cephalosporins possess side-chains that are dissimilar to those of penicillins, leading to low cross-reactivity. In the assessment of cross-reactivity between penicillins and cephalosporins, one has to take into account the background beta-lactam hypersensitivity, which occurs in up to 10% of patients. Cross-reactivity based on skin testing or in-vitro test occurs in up to 50% and 69% of cases, respectively. Clinical reactivity and drug challenge test suggest an average cross-reactivity rate of only 4.3%. For third- and fourth-generation ...

Bacterial infections are common in the neonates and are a major cause of morbidity and mortality. Sixty percent of preterm infants admitted to neonatal intensive care units received at least one antibiotic during the first week of life. Penicillins, aminoglycosides and cephalosporins comprised 53, 43 and 16%, respectively. Kinetic parameters such as the half-life (t1/2), clearance (Cl), and volume of distribution (Vd) change with development, so the kinetics of penicillins, cephalosporins and aminoglycosides need to be studied in order to optimise therapy with these drugs. The aim of this study is to review the pharmacokinetics of penicillins, cephalosporins and aminoglycosides in the neonate in a single article in order to provide a critical analysis of the literature and thus provide a useful tool in the hands of physicians. The bibliographic search was performed electronically using PubMed, as the search engine, until February 2nd, 2010. Medline search terms were as follows: pharmacokinetics AND
Cefuroxime Axetil is the name of the medication. It comes in the form of a tablet, and should be taken by mouth. It belongs to a class of medications called Cephalosporin Antibiotic.
CEPHALOSPORINS. The first-generation cephalosporins represented by the oral drugs cephalexin and cefadroxil, and the injectable drug cefazolin have a spectrum of activity that includes staphylococci, streptococci, and many of the enteric gram-negative bacilli. However, resistance among gram-negative bacteria develops easily, primarily from synthesis of ß-lactamase enzymes that can hydrolyze these drugs. Extended-spectrum cephalosporins include those from the 2nd, 3rd, and 4th generation have been used in resistant infections caused by Escherichia coli, Klebsiella pneumoniae, Enterobacter species, Proteus species (especially indole-positive), and Pseudomonas aeruginosa. Of the 2nd-generation cephalosporins, the ones used most often in veterinary medicine are cefoxitin and cefotetan. Their use has been valuable for treating organisms resistant to the 1st generation cephalosporins or in cases in which there are anaerobic bacteria present. Anaerobic bacteria such as those of the Bacteroides ...
Second-order rate constants for the alkaline hydrolysis of 3-thiol substituted cephalosporins are independent of the pKa of the thiol over a pKa range of 9. If there is a leaving group at C-3 it is expelled after the -lactam ring is opened and the expulsion of the leaving group does not enhance the rate of -lactam C-N bond fission. The zinc enzyme -lactamase II is about a 100-fold better catalyst than the serine enzyme -lactamase I for the hydrolysis of the same cephalosporin. The second-order rate constant kcat/Km for both -lactamase enzymes shows no dependence on the nature of the substituent at C-3 which is not explicable by the different chemical reactivity of the cephalosporins. There is no evidence for a significant recognition site in either enzyme for the C-3 substituent. The kinetic parameters kcat and Km for the -lactamase I-catalysed hydrolysis may be complicated by the formation of intermediates.. ...
Antimicrobial resistance is an increasing problem in Neisseria gonorrhoeae (NG) treatment. Presently, third-generation parenteral cephalosporins, like ceftriaxone and cefotaxime, are the first option. Resistance to oral, but not to parenteral, third-generation cephalosporins has been reported previously. We analysed the microbial susceptibility (as minimum inhibitory concentration - MIC) of NG cultures obtained from high-risk visitors of the largest Dutch outpatient clinic for sexually transmitted infections (STI) in Amsterdam, the Netherlands. Among 1,596 visitors, we identified 102 patients with at least one NG isolate with reduced susceptibility to cefotaxime (0.125 μg/ml < MIC ≤ 0.5 μg/ml). The percentage of NG isolates with reduced susceptibility to cefotaxime rose from 4.8% in 2006 to 12.1% in 2008 (chi2 17.5, p<0.001). With multivariate logistic regression, being a man who has sex with men (MSM) was significantly associated with reduced susceptibility to cefotaxime (p<0.001).
Conditions have been established for identification and quantification of cefuroxime axetil and cefuroxime by thin-layer chromatography and densitometry. Good separation of these compounds was achieved on silica gel by use of chloroform-ethyl acetate-glacial acetic acid-water, 4:4:4:1 (v/v), as mobile phase. UV densitometry was used to detect spots on chromatograms. Under these conditions the limits of detection for cefuroxime axetil and cefuroxime were 40 ng and 30 ng, respectively. Recoveries of cefuroxime axetil and cefuroxime were 99.93% and 97.94%, respectively. ...

Antimicrobial therapy for Neiserria gonorrhoeae is a major public health concern with high rates of resistance to penicillin, tetracycline and fluoroquinolones detected in England and Wales in the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP) (GRASP 2008 Report: Trends in Antimicrobial Resistant Gonorrhoea. Health Protection agency. http://www.hpa.org.uk/Publications/InfectiousDiseases/HIVAndSTIs/0906GRASP2008/ last accessed 26 July 2010). Currently, third-generation oral cephalosporins, such as cefixime or injectable ceftriaxone, are recommended as first-line therapy. However, low-level increases in minimum inhibitory concentrations (MIC) for cephalosporins are now widely reported,1 and reports of azithromycin resistance2 further highlight reduced therapeutic options. Recommendations to limit spread of cephalosporin resistance may well include combination and even prolonged therapy, but these undermine clinical desirability for a single observable dose.. However, there ...
Objective: To evaluate the in vitro activity of the fourth-generation cephalosporin cefpirome in comparison to that of ceftazidime, ceftriaxone, cefotaxime and imipenem in a multicenter study involving nine hospitals from six cities (four states). Material and methods: A total of 804 isolates from patients hospitalized in either intensive care units or Oncology/Hematology units was evaluated. The isolates were collected between June and November of 1995, i.e. before cefpirome became commercially available in Brazil, and susceptibility tested by broth microdilution following the NCCLS procedures. All isolates resistant to cefpirome were retested by B-test. Results: Against Enterobacteriaceae (n = 344), cefpirome demonstrated an activity 2 to 32-fold higher than that of the third-generation cephalosporins (TGCs) and similar to that of imipenem. The percentages of Enterobacteriaceae susceptible were: 88%, 69% and 96% for cefpirome, TGCs and imipenem, respectively, The cefpirome spectrum were ...

Second-generation cephalosporin for oral and injection or parenteral administration. Like most cephalosporins for which data are available, excretion occurs in breast milk in very small amount and it is clinically insignificant (Voropaeva 1982, Amiraslanova 1985, Nakamura 1987). No adverse effects reported in breasted infants (Benyamini 2005). Intravenously administered Cefuroxime salt is not orally absorbed. Cephalosporins are widely used in the Pediatric practice with a good tolerance, even in the neonatal period, so it is very unlikely that in small amounts through milk would be a cause of problems in the infant. Be aware of the possibility of false negative results of cultures in febrile infants whose mothers are taking antibiotics as well as the possibility of gastroenteritis (Ito 1993) by altering the intestinal flora.
