Cefditoren (ME 1206) is a new cephalosporin available for oral administration as the pivaloyloxymethyl ester (ME 1207). The effect of medium formulation. pH, cation concentration and inoculum on the in vitro activity of cefditoren was investigated prior to determining its comparative antibacterial potency against a wide range of clinical bacterial isolates, its bactericidal activity against susceptible strains and the duration of its post-antibiotic effect (PAE). Cefditoren was shown to possess a broad-spectrum of cidal antibacterial activity against both Gram-positive and Gram-negative species with stability to many beta-lactamases of clinical importance. Its activity against Gram-positive species was similar to augmentin and cefuroxime, but superior to that of cefaclor and cefixime, while its beta-lactamase stability was similar to that of cefixime and ceftazidine, characterizing it as a third generation cephalosporin. Investigation of the effect of laboratory variables on the in vitro activity of cefditoren indicates that it will present no special problems when tested in the clinical setting against bacterial pathogens. PAE of 0.9 h, or greater, for Staphylococcus spp, Streptococcus pneumoniae and Moraxella catarrhalis may support the use of an extended dose-interval when cefditoren is used for the treatment of respiratory tract infections. augmentin bid 400 57.
Augmentin is a new combination manufactured by Smith Kline Beecham (Great Britain). It is composed of amoxycillin and clavulanic acid and has antibacterial activity. Augmentin was used in clinical trials in the therapy of 50 adult patients with suppurations after surgical operations on the organs of the abdominal cavity, general staphylococcal infections, pneumonia and prophylactically during the preoperative period. It was also used in the treatment of 30 children patients with bronchopulmonary affections and inflammatory otorhinolaryngological diseases. The clinical trials were performed in the Clinic of Infectious Diseases of the N. G. Gabrichevskiĭ Moscow Research Institute of Epidemiology and Microbiology. For comparison ampicillin was used in the trials. Augmentin was shown to be an efficient formulation with antibacterial activity which could be successfully used in the parenteral therapy of severe affections due to organisms sensitive to it. In the treatment of the children patients with pneumonia augmentin by its therapeutic efficacy proved to be superior to ampicillin. The tolerance of augmentin was good. augmentin penicillin allergy.
