The pharmacokinetic properties of amoxicillin and clavulanic acid when used alone or in combination may be different and show interaction between these two agents that might decrease the absolute bioavailability of clavulanic acid. In an open, randomized, replicated Latin square under fasting condition, pharmacokinetics of new formulations of amoxicillin/clavulanic acid were compared with...

Nowadays Microbial biotechnology is considered as one of the most important and profitable branches of industry. In this approach, by using the generator microorganisms, We are able to produce biotechnological products, with higher efficiency. Clavulanic acid is being used in combination with commonly used beta-lactam antibiotics in order to fight against bacterial infections that are resistant...

An approximately 12.5-kbp region of DNA sequence from beyond the end of the previously described clavulanic acid gene cluster was analyzed and found to encode nine possible open reading frames (ORFs). Involvement of these ORFs in clavulanic acid biosynthesis was assessed by creating mutants with defects in each of the ORFs. orf12 and orf14 had been previously reported to be involved in clavulan...

Clavulanic acid is a potent inhibitor of B-lactamase that is increasingly prescribed in association with amoxicillin. We report 2 cases of patients who experienced pruritus, wheals, and angioedema after oral intake of amoxicillin/clavulanic acid. Routine skin tests for B-lactam antibiotics and specific immunoglobulin (Ig) E were negative in both patients. Analysis of CD63 expression by the baso...

The pharmacokinetics and bacteriological efficacy of ticarcillin and clavulanic acid administered individually or in combination were assessed in rabbits with experimental Escherichia coli K-1 and Haemophilus influenzae type b meningitis. The mean penetrations into the cerebrospinal fluid (CSF) of infected animals after a single dose of ticarcillin-clavulanic acid were approximately 11 and 28% ...

The β-lactamase inhibitor, clavulanic acid is frequently used in combination with β-lactam antibiotics to treat a wide spectrum of infectious diseases. Clavulanic acid prevents drug resistance by pathogens against these β-lactam antibiotics by preventing the degradation of the β-lactam ring, thus ensuring eradication of these harmful microorganisms from the host. This systematic review provides...

Clavulanic acid is produced industrially by fermentation of Streptomyces clavuligerus and researches have increased its production by strain improvement, recombinant DNA technology, and media composition and growth condition optimization. The main objective of this study was to increase the level of clavulanic acid production from Streptomyces clavuligerus (DSM 738), using UV irradiation. After...

OBJECTIVES To analyse an Italian database of spontaneous reporting of suspected adverse drug reactions in order to compare the safety profile of amoxicillin and amoxicillin/clavulanic acid. METHODS Data were retrieved from the spontaneous reports collected by six Italian regions (the GIF database) from January 1988 to June 2005. Drug utilization data were also available for the two drugs. The...

Urinary tract infection caused by beta-lactamase-producing bacteria were treated with 500 mg of amoxicillin three times daily plus either 250 or 125 mg of clavulanic acid three times daily. The overall cure rate was 63.6%, 77.7% with the high dose of clavulanic acid and 53.8% with the low dose. Gastrointestinal intolerance was common in the high-dose clavulanic acid regimen.

Augmentin is a new antibacterial formulation comprised of amoxicillin and the beta-lactamase inhibitor clavulanic acid. In the present paper, the use of high-performance liquid chromatography (HPLC) to provide a rapid assay of the components of Augmentin in body fluids is described. Clavulanic acid was assayed by reacting the sample with imidazole, which readily produces a derivative absorbing ...
