    Cefquinome is an antibacterial drug of the cephalosporin group which acts by inhibition of cell wall synthesis. It is characterised by its broad therapeutic spectrum of activity and a high stability against beta-lactamases.

    • Pharmacodynamic properties

      In vitro, Cefquinome has antibiotic activity against common Gram negative and Gram positive bacteria including Escherichia coli, Staphylococcus aureus, Streptococcus dysgalactiae, Streptococcus agalactiaeand Streptococcus uberis.

    • Pharmacokinetic properties

      After intramammary administration, a mean concentration of 19 mcg/ml in milk is observed 12 hours post last infusion. The highest MIC 90 value was found for Staphylococcus aureus. This pathogen has a MIC 90 in the range of 1 µg/ml.
      At the second milking following the last infusion the mean concentration is still approximately 2.5 mcg/ml and then falls to 0.75 mcg/ml at the third milking post last infusion.

      Resorption of cefquinome from the udder is insignificant.
