The objective of this study was to compare the cost effectiveness of amoxicillin/clavulanic acid with other antibacterial regimens for prophylaxis of infection after elective abdominal or gynaecological surgery. Data from 21 previously published comparative clinical trials were used to calculate statistical confidence intervals for differences in postoperative wound infection rate. A simple mod...

Co-amoxiclav is a fixed combination of the sodium salt of amoxicillin (amoxiNa) and the potassium salt of clavulanic acid (clavK). Although clavulanic acid has weak antibacterial activity when used alone, its combination with certain penicillins results in a synergistic effect which expands the spectrum of activity of the penicillin against many strains of beta-lactamase producing bacteria. Pre...

The rise of multi- and even totally antibiotic resistant forms of Mycobacterium tuberculosis underlines the need for new antibiotics. The pathogen is resistant to β-lactam compounds due to its native serine β-lactamase, BlaC. This resistance can be circumvented by administration of a β-lactamase inhibitor. We studied the interaction between BlaC and the inhibitor clavulanic acid. Our data show ...

Strains of bacteria resistant to beta-lactam antibiotics have been increasing in number and are becoming troublesome in clinical medicine. The in vitro antibacterial activity of amoxicillin combined with clavulanic acid was determined on selected ampicillin-resistant clinical isolates. Synergistic effects were produced by amoxicillin with clavulanic acid against ampicillin-resistant strains of ...

metal ions are the main impurities of water and media ingredients used in fermentation processes. in this research, the effect of ca+2, co+2, cu+2, fe+2, mg+2, mn+2 and zn+2 as chloride and sulfate salts was studied on the clavulanic acid production and streptomyces clavuligerus growth. all chloride salts had negative effect on clavulanic acid production and no clavulanic acid was produced in t...

BACKGROUND When prescribing antibiotics for common indications, clinicians need information about both harms and benefits, information that is currently available only from observational studies. We quantified the common harms of the most frequently prescribed antibiotic, amoxicillin, from randomized placebo-controlled trials. METHODS For this systematic review, we searched MEDLINE, Embase an...

We present 10 cases (6 males and 4 females) of children aged 4 to 12 years, who were diagnosed with allergy to clavulanic acid (CL) and treated in the Paediatric Allergy Section of the University Hospital Dr. Peset in Valencia from 2000 to 2005. The children reported symptoms of urticaria and angio-oedema after receiving orally-administered amoxicillin/clavulanic acid (A-CL) for an infection. D...

The activities of ampicillin, ampicillin-sulbactam, amoxicillin, amoxicillin-clavulanic acid, ticarcillin, ticarcillin-clavulanic acid, piperacillin, piperacillin-tazobactam, aztreonam, and aztreonam-clavulanic against Stenotrophomonas maltophilia strains for which the MICs of penicillins and commercially available b-lactam– b-lactamase inhibitor combinations were higher than the breakpoints us...

Clavulanic acid, sulbactam, and tazobactam are inhibitors of a variety of plasmid-mediated beta-lactamases. However, inhibition data for these three inhibitors with a wide range of different plasmid-mediated beta-lactamases have not yet been compared under the same experimental conditions. A number of groups have inferred that clavulanic acid inhibits extended-spectrum TEM and SHV beta-lactamas...
