Renal tolerance of cefpirome (HR 810), a new cephalosporin antibiotic.
An open study was carried out in ten healthy, male volunteers in order to investigate the renal tolerance of cefpirome (HR 810), a new cephalosporin antibiotic. Subjects received a single dose of 1.0 g of cefpirome and then repeated doses of 1.0 g of cefpirome twice daily for five days. Urine was collected in several fractions during the study and the urine excretion, excretions of creatinine, ...
متن کاملComparative effects of cefpirome (HR 810) and other cephalosporins on experimentally induced pneumonia in mice.
The chemotherapeutic efficacy of cefpirome (HR 810), a new polar aminothiazolylcephalosporin and that of ceftazidime, cefotaxime, cefoperazone, latamoxef and cefodizime were examined against experimental pneumonia caused by Klebsiella pneumoniae DT-S in mice. When compared in terms of MIC values against the infecting organism and the pharmacokinetic pattern, cefpirome showed equal activity and ...
متن کاملStability of Cefpirome Sulfate in Aqueous Solutions.
The influence of pH on the stability of cefpirome sulfate was investigated in the pH range of 0.44 - 13.00. The degradation of cefpirome sulfate as a result of hydrolysis was a pseudo-first-order reaction. General acid-base hydrolysis of cefpirome sulfate was not observed. In the solutions of hydrochloric acid, sodium hydroxide, acetate, borate and phosphate buffer, k(obs) = k(pH) because speci...
متن کاملCefpirome (HR 810): lack of selection of beta-lactamase overproducing variants.
With respect to the selection of beta-lactam-resistant variants marked discrepancies between the recently developed cephalosporin HR 810 and other recently developed cephalosporins could be observed: beta-lactam resistant subpopulations did not emerge during a 16-hour culture in the presence of the 20-fold minimal inhibitory concentration in a clinical Enterobacter cloacae isolate (2240/81) in ...
متن کاملSonochemical degradation of azithromycin in aqueous solution
Background: The presence of pharmaceutical substances and their residual in water resources is an important environmental concern. Azithromycin, an antibiotic that is used for the treatment of infectious diseases, is a pollutant agent in the wastewater. The aim of this study was to investigate azithromycin degradation in aqueous solution through ultrasonic process in the presence of zinc oxide ...
