The penetration of amoxycillin/clavulanic acid into peritoneal fluid. 1983

R Wise, and I A Donovan, and J Drumm, and J M Andrews, and P Stephenson

Thirty patients undergoing elective abdominal surgery were given 1 g amoxycillin plus 0 . 2 g clavulanic acid as a single intravenous injection at varying times prior to the operation. Sterile assay discs were placed on the peritoneal surface in order to measure peritoneal fluid levels of each agent. Simultaneous serum levels were also measured. A total of 44 simultaneous serum and peritoneal samples were analysed. There was rapid penetration of both agents into peritoneal fluid. The mean peritoneal fluid levels of amoxycillin were 84% (S.D. 34) of the serum level and 66% 42) for clavulanic acid. The peritoneal levels of both agents declined in parallel to the serum levels (the half-lives all being about 1 h) and the ratio of amoxycillin: clavulanic acid in serum and peritoneal fluid was similar to that as administered.

UI	MeSH Term	Description	Entries
D002969	Clavulanic Acids	Acids, salts, and derivatives of clavulanic acid (C8H9O5N). They consist of those beta-lactam compounds that differ from penicillin in having the sulfur of the thiazolidine ring replaced by an oxygen. They have limited antibacterial action, but block bacterial beta-lactamase irreversibly, so that similar antibiotics are not broken down by the bacterial enzymes and therefore can exert their antibacterial effects.

D000658	Amoxicillin	A broad-spectrum semisynthetic antibiotic similar to AMPICILLIN except that its resistance to gastric acid permits higher serum levels with oral administration.

D019818	Clavulanic Acid	A beta-lactam antibiotic produced by the actinobacterium Streptomyces clavuligerus. It is a suicide inhibitor of bacterial beta-lactamase enzymes. Administered alone, it has only weak antibacterial activity against most organisms, but given in combination with other beta-lactam antibiotics it prevents antibiotic inactivation by microbial lactamase.
