Sarmoxicillin, an amoxicillin prodrug, is the methoxymethyl ester of hetamoxicillin. Esterification converted amoxicillin from an amphoteric to a cationic compound and resulted in a 30- to 600-fold increase in lipid partitioning. Oral absorption studies in normal subjects demonstrated that sarmoxicillin was only partially hydrolyzed by nonenzymatic and gut or hepatic first-pass metabolism and t...

The aim of this study was to compare the efficacy and tolerability of the first-line Helicobacter pylori (H. pylori) eradication regimen composed of proton pump inhibitor, clarithromycin, and amoxicillin, with those of a regimen composed of proton pump inhibitor, metronidazole, and amoxicillin. Data of patients, who were administered the first-line H. pylori eradication regimen at Tokyo Medical...

The activity of Ro 19-5247 (the active metabolite of the oral cephalosporin Ro 19-5248 [T-2588]) was compared with that of five orally active agents against a total of 331 bacterial strains. Ro 19-5247 was more active in vitro than amoxicillin, amoxicillin-clavulanate, cefaclor, cefuroxime, and cephalexin against members of the family Enterobacteriaceae. Amoxicillin-clavulanate and amoxicillin ...

Most Helicobacter pylori strains are susceptible to amoxicillin, an important component of combination therapies for H. pylori eradication. The isolation and initial characterization of the first reported stable amoxicillin-resistant clinical H. pylori isolate (the Hardenberg strain) have been published previously, but the underlying resistance mechanism was not described. Here we present evide...

A 7-day course of either cephradine or amoxicillin-clavulanate treatment caused no significant change in fecal flora composition, except that staphylococci were virtually eliminated in both groups. Some amoxicillin-resistant coliforms were isolated after treatment in both groups, but cephradine- or amoxicillin-clavulanate-resistant coliforms were rarely isolated.

Objective: The study was planed to see bioavailability and disposition kinetics of amoxicillin in adult rabbits (irrespective of sex) under healthy and induced febrile conditions. Design: Comparative Place and duration of study: Study was conducted at the department of pharmacology, University of Veterinary and Animal Sciences, Lahore from January 2003 to July 2003. Methodology: Initially all r...

CONTEXT The high prevalence of resistance to trimethoprim-sulfamethoxazole and other antimicrobials among Escherichia coli causing acute cystitis in women has led to increased use of alternative antibiotics. One such antibiotic, amoxicillin-clavulanate, has not been well studied. OBJECTIVE To compare the efficacy of a 3-day regimen of amoxicillin-clavulanate to that of a 3-day regimen of cipr...
