The principal cause of bacterial resistance to penicillin and other b-lactam antibiotics is the acquisition of plasmid-encoded b-lactamases, enzymes that catalyze hydrolysis of the b-lactam bond and render these antibiotics inactive. Clavulanic acid is a potent inhibitor of b-lactamases and has proven clinically effective in combating resistant infections. Although clavulanic acid and penicilli...

The activity of Ro 15-8074/001 was compared with that of cefaclor, amoxicillin-clavulanic acid, trimethoprim-sulfamethoxazole, norfloxacin, and ceftriaxone against 225 clinical isolates. It was more active than cefaclor, amoxicillin-clavulanic acid, and trimethoprim-sulfamethoxazole against members of the family Enterobacteriaceae and Haemophilus influenzae and had activity similar to that of c...

Clavulanic acid is a ß-lactam antibiotic which has a potent ß-lactamase inhibiting activity. In order to optimize its production by the new isolate Streptomyces DAUFPE 3060, the influence of two independent variables, temperature and soybean flour concentration, on clavulanic acid and biomass concentrations was investigated in 250 mL-Erlenmeyers according to a 2(2) central composite design. To ...

The efficacy and safety of amoxicillin-clavulanic acid were compared with those of co-trimoxazole in the treatment of acute urinary tract infections. A total of 104 patients (mean age, 52 years) with clinical and laboratory evidence of acute urinary tract infection were enrolled in the study. Characteristics and infecting organisms were equivalent in both groups of patients. Escherichia coli wa...

Amoxicillin-clavulanic acid was compared with ampicillin-sulbactam in preventing the development of mixed infections produced in mice by subcutaneous inoculation of amoxicillin-resistant strains of Bacteroides fragilis and Escherichia coli. At doses designed to produce concentrations in mouse plasma similar to those obtained in humans, both amoxicillin-clavulanic acid and ampicillin-sulbactam w...

Amoxicillin-Clavulanic acid continues to be one of the most commonly used antibiotic combinations. Hepatic injury due to this antibiotic is rare. We report a case of amoxicillin-clavulanic acid induced hepatitis causing painless jaundice to bring to attention this rare side effect of this commonly used antibiotic. This is a case of a 62-year-old Caucasian female, who presented with acute onset ...

Thirty-eight patients undergoing elective abdominal surgery were given 3.0 g ticarcillin plus 0.2 g clavulanic acid as a single intravenous injection at varying times prior to the operation. Sterile assay discs were placed on the peritoneal surface in order to measure peritoneal fluid levels of each agent. Simultaneous serum levels were also measured. A total of 38 serum and peritoneal samples ...
