Infants and young children, especially those in day care, are at risk for recurrent or persistent acute otitis media (AOM). There are no data on oral alternatives to high-dose amoxicillin-clavulanate for treating AOM in these high-risk patients. In this double-blind, double-dummy multicenter clinical trial, we compared a novel, high-dose azithromycin regimen with high-dose amoxicillin-clavulana...

The activities of ampicillin-sulbactam and amoxicillin-clavulanate were studied with 100 selected clinical Escherichia coli isolates with different beta-lactam susceptibility phenotypes by standard agar dilution and disk diffusion techniques and with a commercial microdilution system (PASCO). A fixed ratio (2:1) and a fixed concentration (clavulanate, 2 and 4 micrograms/ml; sulbactam, 8 microgr...

A simple, specific, accurate, and precise reverse phase high-performance liquid chromatographic method for analysis of Cefuroxime axetil and Potassium clavulanate has been developed. Separation of drugs was carried out on Jasco HPLC system with Hypersil Gold C-18 column (250 mm × 4.6 mm i.d.), using 0.01M Potassium dihydrogen phosphate: methanol 60: 40 (v/v) as mobile phase. Quantitation of dru...

This report describes the results of a review that was done to compare, from the patients' and their parents' perspective, costs involved in treating acute otitis media in children with amoxicillin/clavulanate potassium or cefpodoxime proxetil. The following costs were included in the analysis: average wholesale price of the initial antibiotic prescribed, cost of initial and follow-up physician...

UNLABELLED Upper respiratory tract infections are the most common causes of medical visits in children and adults, demanding massive use of antibiotics. Bacterial resistance caused by beta-lactamase is one of the most serious problems in this matter. Sultamicillin, a double pro-drug of Ampicillin/Sulbactan, is a potent beta-lactamase inhibitor which can face this challenge. AIM Evaluate effic...

Clinical experience on meropenem-clavulanate to treat tuberculosis (TB) is anecdotal (according to case reports on 10 patients). The aim of our case-control study was to evaluate the contribution of meropenem-clavulanate when added to linezolid-containing regimens in terms of efficacy and safety/tolerability in treating multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB cases aft...

Clavulanate is a broad-spectrum beta-lactamase inhibitor, with activity against many of the chromosomally and plasmid-mediated beta-lactamases of both Gram-positive and Gram-negative bacteria. Although clavulanate has minimal antibacterial activity in vitro, accumulating evidence suggests that it may have an effect on pathogenic bacteria regardless of beta-lactamase production. Like other beta-...

This is the first prospective clinical trial in which patients with acute bacterial exacerbation of chronic bronchitis have been stratified by degree of underlying illness. Uncomplicated patients were randomised to levofloxacin 750 mg once daily (q.d.) for 3 days or azithromycin q.d. for 5 days. Complicated patients were randomised to levofloxacin 750 mg q.d. for 5 days or amoxicillin 875 mg/cl...

The effect on the nasopharyngeal flora of 7 days of amoxicillin-clavulanate or 5 days of 800 mg once a day was studied in 50 adults with acute sinusitis. The numbers of potential pathogens and interfering alpha-hemolytic streptococci were equally reduced after both therapies. However, the number of interfering Prevotella spp. declined more significantly after amoxicillin-clavulanate treatment.

Two dosages of a liquid suspension formulation of amoxicillin and potassium clavulanate were tested in 34 infants and children. The smaller dosage resulted in suboptimal plasma concentrations. With a greater dosage (3.3 mg of clavulanate per kg and 13.3 mg of amoxicillin per kg), the mean peak plasma concentrations were 1.6 micrograms clavulanic acid per ml and 4.9 micrograms amoxicillin per ml.
