A study of amoxicillin pharmacokinetics was conducted in healthy goats and goats with chronic lead intoxication. The intoxicated goats had increased serum concentrations of liver enzymes (alanine aminotransferase and γ-glutamyl transferase), blood urea nitrogen, and reactivated δ-aminolevulinic acid dehydratase compared to the controls. Following intravenous amoxicillin (10 mg/kg bw) in control...

The effect of homogeneous fibrin (Fb), collagen (Coll) and composite fibrin-heparin (Fb-Hp), fibrin-collagen (Fb-Coll) membranes on in vitro release of platelet-derived growth factor (PDGF-BB) was evaluated in the presence or absence of amoxicillin using of the ELISA immunoassay test. Amoxicillin concentration was determined spectrophotometrically at 272 nm. The process of the PDGF-BB growth fa...

Previous studies showed that sub-MIC levels of β-lactam antibiotics stimulate biofilm formation in most methicillin-resistant Staphylococcus aureus (MRSA) strains. Here, we investigated this process by measuring the effects of sub-MIC amoxicillin on biofilm formation by the epidemic community-associated MRSA strain USA300. We found that sub-MIC amoxicillin increased the ability of USA300 cells ...

The amoxicillin-clavulanate combination (Augmentin) frequently induces gastric complaints and diarrhea by an unknown mechanism. The aim of this study was to assess the effects of two orally therapeutic regimens of amoxicillin-clavulanate on small bowel motility in human beings. Duodeno-jejunal manometric recordings were performed in six healthy subjects treated in a cross-over double-blind stud...

The synthesis of amoxicillin with immobilized penicillin G acylase (PGA) in aqueous medium was investigated. The parameters studied were: time course of amoxicillin production, concentration of substrates: hydroxyphenylglycine methyl ester (HPGM) and 6-aminopeicillanic acid (6APA) and the e ect of enzyme (PGA) content and pH, under variable and constant conditions and temperature variations. In...

A single intravenous dose of 2.0 g of amoxicillin and 0.2 g of potassium clavulanate was given to patients with bacterial meningitis, and the pharmacokinetics of both drugs in the cerebrospinal fluid (CSF) and plasma were evaluated. Twenty-one patients aged 14 to 76 years were studied. Both amoxicillin and potassium clavulanate were detectable in the CSF as early as 1 h and reached peak concent...

PURPOSE This study evaluated the costs and utility of observation and routine antibiotic treatment options for children with acute otitis media. METHODS The cost-effectiveness analysis was performed among children aged 6 months to 12 years seen in primary care offices. The interventions studied were watchful waiting as practiced in the Netherlands, delayed prescription, 5 days of amoxicillin,...

AIM To investigate the prevalence of Porphyromonas gingivalis in root canals of infected teeth with periapical abscesses and to investigate the antimicrobial susceptibility of this species to some frequently prescribed antibiotics. METHODOLOGY Samples were obtained from 70 root canals of abscessed teeth. Microbial sampling, isolation and bacterial identification were accomplished using approp...

OBJECTIVES Amoxicillin and clarithromycin have been proven to be effective in the treatment of community-acquired pneumonia. This study investigated the in vivo bactericidal efficacy of a novel, pulsatile dosing strategy for amoxicillin and clarithromycin, when used as monotherapy and combination therapy. METHODS A neutropenic murine pneumonia model was used to assess the bactericidal activit...

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...
