An in-vitro kinetic model was used to demonstrate the bactericidal activity of concentrations of temocillin achieved in extravascular body fluids following a 1 g intravenous dosage in man. Concentrations of temocillin attainable in peripheral lymph were bactericidal for ampicillin-resistant strains of Escherichia coli, Enterobacter cloacae and Klebsiella oxytoca. Likewise, concentrations of temocillin achieved in human blister fluid following a 12-hourly dosage regimen were bactericidal for cultures of Ent. cloacae and K. oxytoca which were resistant, respectively, to simulated blister fluid concentrations of cefotaxime and aztreonam. The bactericidal activity of extravascular concentrations of temocillin against these multiresistant, Gram-negative bacteria was a reflection of the beta-lactamase-stability and good pharmacokinetic properties of temocillin.

D010406	Penicillins	A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.
