OBJECTIVE To compare the effects on the nasopharyngeal flora of therapy of acute otitis media in children with either a low dose or a high dose of amoxicillin. DESIGN Retrospective study. PATIENTS Of 50 children diagnosed as having acute otitis media, 25 received a low dose of amoxicillin (45 mg/kg/d) (group 1) and 25 received a high dose of amoxicillin (90 mg/kg/d) (group 2) for 10 days, a...

Single-doses or short-term administration of beta-lactam antibiotics alone or combined with aminoglucoside antibiotics have failed to consistently prevent experimental streptococcal endocarditis induced by high inocula of bacteria poorly susceptible to killing by these antibiotics. The optimal duration of administration of antibiotics for successful prophylaxis under these circumstances has not...

In a randomized, double-blind, placebo-controlled trial involving 518 infants and children who had otitis media with effusion ("secretory" otitis media), we evaluated the efficacy of a two-week course of amoxicillin (40 mg per kilogram of body weight per day) with and without a four-week course of an oral decongestant-antihistamine combination. Among the 474 subjects who were evaluated at the f...

Antibiotics have recently gained in popularity due to their usage medical treatment and the process of removing them from environment. Amoxicillin is one antibiotics that constitutes study's subject. On a Pt disc electrode cobalt hydroxide modified-Pt electrode, scan rate pH electrochemical oxidation amoxicillin were investigated. The voltammetry measurement's current peak revealed changing sur...

PURPOSE The efficacy of antibiotic therapy for acute sinusitis is controversial. This study aimed to compare the efficacies of amoxicillin with nasal irrigation and nasal irrigation alone for acute sinusitis in children. METHODS This randomized, double-blind, controlled study included 80 children aged 4-15 years with a clinical presentation of acute sinusitis. Patients were randomly assigned ...

A European placebo-controlled trial of antibiotic treatment for lower respiratory tract infection (LRTI) conducted in 16 primary care practices networks recruited participants between November 2007 and April 2010, and found adverse events (AEs) occurred more often in patients prescribed amoxicillin compared to placebo. This secondary analysis explores the causal relationship and estimates speci...

Amoxicillin (alpha-amino-p-hydroxybenzyl penicillin, BRL 2333) is a new semisynthetic penicillin which is structurally similar to ampicillin, but which is better absorbed and yields higher concentrations in serum and urine. The in vitro susceptibility of 145 strains of Enterobacteriaceae and 30 isolates of Pseudomonas aeruginosa was determined against various concentrations of amoxicillin and a...

OBJECTIVE To compare clinical and bacteriologic responses to intramuscular benzathine penicillin G (BPG) and single dose of amoxicillin in Group A streptococcal (GAS) pharyngitis. DESIGN This study included 571 children from 6 to 15 years old age, with pharyngitis, who were admitted to 45 elementary and guidance schools from 7 regions of Education Organization in North-East of Iran, Mashhad. ...

OBJECTIVE To compare the effects of cefdinir (14 mg/kg per day) and amoxicillin (90 mg/kg per day) antimicrobial therapy on the nasopharyngeal flora of children with acute otitis media. DESIGN Nasopharyngeal cultures for aerobic and facultative bacteria were obtained before therapy and 2 to 4 days after completion of therapy. SETTING Outpatient clinic. PATIENTS Fifty children, aged 7 mont...

OBJECTIVES Although most susceptibility studies for linezolid have investigated aerobic bacteria, only a few have investigated anaerobe isolates. The aim of the present study was to determine the antibacterial activity of linezolid against a larger sample of clinical isolates of Fusobacterium spp. and to report on the detailed susceptibility, stratified by species. METHODS The in vitro suscep...
