Probenecid and the antibacterial activity of cephradine in vivo. 1978

M W Kunst, and H Mattie

The influence of probenecid on the concentrations in blood and antibacterial efficacy of cephradine was studied in experimentally infected mice. An infection was induced by injection of 5 X 10(6) Escherichia coli into the thighs of irradiated, granulocytopenic mice. Probenecid was given 1 hr later, just before the administration of cephradine. The control animals received only the vehicle. Concentrations of cephradine in blood were determined for 2 hr; the antibacterial activity was estimated from bacterial counts made in the homogenized individual thighs. The blood concentrations of cephradine were 1.77 times higher in the probenecid-treated animals than in the controls. The potency ratio for doses was 2.41, the potency ratio for the areas under the drug concentration in blood vs. time curves was 1.34, and that for the peak blood concentrations was 1.43.

D011339	Probenecid	The prototypical uricosuric agent. It inhibits the renal excretion of organic anions and reduces tubular reabsorption of urate. Probenecid has also been used to treat patients with renal impairment, and, because it reduces the renal tubular excretion of other drugs, has been used as an adjunct to antibacterial therapy.

D002511	Cephalosporins	A group of broad-spectrum antibiotics first isolated from the Mediterranean fungus ACREMONIUM. They contain the beta-lactam moiety thia-azabicyclo-octenecarboxylic acid also called 7-aminocephalosporanic acid.

D003864	Depression, Chemical	The decrease in a measurable parameter of a PHYSIOLOGICAL PROCESS, including cellular, microbial, and plant; immunological, cardiovascular, respiratory, reproductive, urinary, digestive, neural, musculoskeletal, ocular, and skin physiological processes; or METABOLIC PROCESS, including enzymatic and other pharmacological processes, by a drug or other chemical.

D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
