    4. Special warnings

      None.

    5. Special precautions for use

      Special precautions for use in animals

      Shake the vial well before using.

      The product does not contain an antimicrobial preservative. Swab the septum before removing each dose. Use a dry sterile needle and syringe. An appropriately graduated syringe must be used to allow accurate administration of the required dose volume. This is particularly important when injecting small volumes, for example when treating piglets. The cap may be safely punctured up to 25 times. The 50ml vial should be used for treating small piglets. When treating groups of animals, use a draw-off needle.

      Use of the product should be based on susceptibility testing and take into account official and local antimicrobial policies.

      To prevent the claimed infections in piglets, attention should be paid to hygiene and ventilation, and overcrowding should be avoided. When the first piglets are affected, careful examination of the other animals of the same pen is recommended to enable an early treatment.

      Special precautions to be taken by the person administering the veterinary medicinal product to animals

      Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillins may lead to cross sensitivity to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.

      • Do not handle this product if you know you are sensitized, or if you have been advised not to work with such preparation.
      • Handle this product with great care to avoid exposure, taking all recommended precautions.
      • If you develop symptoms following exposure such as a skin rash, you should seek medical advice and show the doctor this warning. Swelling of the face, lips or eyes or difficulty with breathing, are more serious symptoms and require urgent medical attention.
    6. Adverse reactions (frequency and seriousness)

      Use of the product may result in localized tissue reaction. Tissue lesions are repaired 15 days after the last administration of the product.
      Hypersensitivity reactions to cephalosporins occur rarely.
      Hypersensitivity type reactions in cattle have been reported as individual isolated cases.

    7. Use during pregnancy and lactation

      There is no available information indicating reproductive toxicity in cattle or pigs. In reproduction toxicity studies in laboratory animals cefquinome did not reveal any effect on reproduction or teratogenic potential.

    8. Interaction with other medicinal products and other forms of interaction

      It is known that a cross sensitivity to cephalosporin exists for bacteria sensitive to the cephalosporin group.

  5. PHARMACOLOGICAL PROPERTIES

    Pharmaceutic group: Cephalosporins and related substances
    ATCvet code: QJ01DA91

    The antibacterial drug Cefquinome is a broad-spectrum cephalosporin of the fourth-generation which acts by inhibition of the cell wall synthesis. It is bactericidal and is characterized by its broad therapeutic spectrum of activity and a high stability against penicillinases and beta-lactamases.

    1. Pharmacodynamic properties

      In vitro activity has been demonstrated against common Gram positive and Gram negative bacteria including Escherichia coli, Citrobacter spp., Klebsiella spp., Mannheimia haemolytica, Pasteurella multocida, Proteus spp., Salmonella spp., Serratia marcescens, Haemophilus somnus, Arcanobacterium pyogenes, Bacillus spp., Corynebacterium spp., Staphylococcus spp., Streptococcus spp., Bacteroides spp., Clostridium spp., Fusobacterium spp., Prevotella spp., Actinobacillus spp. and Erysipelothrix rhusiopathiae.
      Bacterial strains were isolated between 1999 and 2002 from cattle and pigs presenting diseases corresponding to target indications in Germany, France, The Netherlands and United Kingdom. From a sample of more than 350 isolates, 97.7% were found to be susceptible to cefquinome (resistance breakpoint of 4 µg/mL). These susceptible strains had MIC levels ranging from < 0.004 to 2 µg/mL.
      Cefquinome as a fourth generation cephalosporin combines high cellular penetration and ß-lactamase stability. In contrast to cephalosporins of previous generations, cefquinome is not hydrolysed by chromosomally-encoded cephalosporinases of the Amp-C type or by plasmid mediated cephalosporinases of some enterobacterial species. However, some Extended Spectrum beta-lactamases (ESBL) can hydrolyse cefquinome and cephalosporins of other generations. The potential for resistance development against cefquinome is rather low. High-level resistance to cefquinome would require the coincidence of two genetic modifications, i.e. hyperproduction of specific ß-lactamases as well as decreased membrane permeability.

    2. Pharmacokinetic particulars

      In cattle peak serum concentrations of about 2 µg/ml are reached within 1.5-2 hours after intramuscular or subcutaneous administration at the dose of 1 mg/kg. Cefquinome has a relatively short half-life (2.5 hours), is < 5 % protein bound and excreted unchanged in the urine. Cefquinome is not absorbed after oral administration.
      In pigs or piglets, at 2 mg/kg dosage, maximum serum concentrations of around 5 µg/ml are measured within 15 to 60 minutes after intramuscular injection. The average half-life is about 9 hours.
      Cefquinome binds poorly to plasma proteins and therefore penetrates into the cerebrospinal fluid (CSF) and the synovial fluid in pigs. The concentration profile is similar between the synovial fluid and the plasma. The concentrations reached in the CSF 12 hours after treatment are similar to those in plasma.
