4. CLINCIAL PARTICULARS
4.1 Target species
Cattle, pigs and horses.
4.2 Indications for use, specifying the target species
Cattle
Treatment of cattle with acute bacterial respiratory disease in which Mannheimia haemolytica, Pasteurella multocida or Histophilus somnisensitive to ceftiofur are involved.
Treatment of cattle with acute interdigital necrobacillosis (foul in the foot) in which Fusobacterium necrophorum and Bacteroides melaninogenicus are involved.
Pigs
Treatment of pigs with bacterial respiratory disease in which Actinobacillus (Haemophilus) pleuropneumoniae, Pasteurella multocidaand/or Streptococcus suissensitive to ceftiofur are involved.
Horses
Treatment of horses with bacterial respiratory disease in which Streptococcusspp including Streptococcus zooepidermicus and Streptococcus equi, Staphylococcus spp and/or Pasteurellaspp are involved.
4.3 Contraindications
Do not use in animals previously found to be hypersensitive to ceftiofur and other b-lactam antibiotics.
Do not use in case of known resistance to the active substance.
Do not use in poultry (including eggs) due to risk of spread of antimicrobial resistance to humans.
4.4 Special warnings for each target species
The administration of antimicrobials to horses under conditions of stress may be associated with acute diarrhoea, which could be fatal. If acute diarrhoea is observed, discontinue use of this antimicrobial and initiate appropriate therapy.
4.5 Special precautions for use
Special precautions for use in animals
Cefenil 50mg/ml Powder and Solvent for Solution for Injection selects for resistant strains such as bacteria carrying extended spectrum betalactamases (ESBL) and may constitute a risk to human health if these strains disseminate to humans e.g. via food. For this reason, Cefenil 50mg/ml Powder and Solvent for Solution for Injection should be reserved for the treatment of clinical conditions which have responded poorly, or are expected to respond poorly (refers to very acute cases when treatment must be initiated without bacteriological diagnosis) to first line treatment. Official, national and regional antimicrobial policies should be taken into account when the product is used. Increased use, including use of the product deviating from the instructions given in the SPC, may increase the prevalence of such resistance. Whenever possible, Cefenil 50mg/ml Powder and Solvent for Solution for Injection should only be used based on susceptibility testing.
Cefenil 50mg/ml Powder and Solvent for Solution for Injection is intended for treatment of individual animals. Do not use for disease prevention or as a part of herd health programmes. Treatment of groups of animals should be strictly restricted to ongoing disease outbreaks according to the approved conditions of use.
If this is not possible, therapy should be based on local (regional, farm level) epidemiological information about susceptibility of the target bacteria and may decrease the effectiveness of treatment with other cephalosporins, due to the potential for cross resistance.
In the pig, particular care must be taken to avoid injection into the fat tissue. See section 4.9.
Avoid repeated injection at the same site.
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 reactions to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.
Do not handle this product if you are sensitised or if you have been advised not to work with such preparations.
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.
Wash hands after use.
4.6 Adverse reactions (frequency and seriousness)
Use of this product may cause transient local discomfort at the site of the injection.
Hypersensitivity reactions can occasionally occur. In the case of an allergic reaction, treatment should be stopped.
In pigs, local irritation at the injection site may occur and can persist for 5 days or more.
4.7 Use during pregnancy, lactation or lay
Laboratory studies in the rat have not produced any evidence of teratogenic, foetotoxic or maternotoxic effects.
The safety of the veterinary medicinal product has not been assessed during pregnancy and lactation in cattle, pigs or horses. Use only according to the benefit/risk assessment by the responsible veterinarian.
4.8 Interaction with other medicinal products and other forms of interaction
None known.
4.9 Amounts to be administered and administration route
This product is for intramuscular use only. See section 4.5(i). Normal aseptic injection technique should be practiced.
Reconstitution
1 g vial: reconstitute by adding 20 ml of water for injection.
4 g vial: reconstitute by adding 80 ml of water for injection.
Directions for Reconstitution:
1. Remove stopper overseal from diluent and sterile powder vials.
2. Remove exactly 20ml (80ml) Water for Injections using a sterile 18G needle and syringe.
3. Inject the exact volume of diluent into sterile powder vial.
4. Shake solution until complete reconstitution of powder occurs.
Rapid addition of diluent maintained at room temperature will give best results. Normally accepted aseptic technique should be followed during reconstitution to avoid microbial contamination.
The resulting solution contains 50 mg of ceftiofur per ml.

In cattle, no evidence of systemic toxicity was observed following administration of an overdose.
In pigs, no evidence of systemic toxicity was observed following the administration of doses of up to 8 times the recommended dose, administered daily by intramuscular injection for 15 days.

5. PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: antibiotic for systemic use.
ATCvet code: QJ01DD90
5.1 Pharmacodynamic properties
The active ingredient, ceftiofur sodium, is a third-generation cephalosporin (beta-lactam antibiotic) which acts against both gram-positive and gram-negative bacteria, including betalactam-producing bacteria. Also its main metabolite, desfuroylceftiofur, shows some antibacterial activity.
Ceftiofur is a bactericidal antibiotic in vitro which acts by interfering with bacterial cell-wall synthesis.
In cattle, ceftiofur is active against the following microorganisms found in respiratory-tract infections: Mannheimia haemolytica, Pasteurella multocida, Histophilussomnias well as the following bacteria responsible for acute interdigital necrobacillosis: Fusobacterium necrophorum and Bacteroides melaninogenicus.
In pigs, ceftiofur is active against the following microorganisms: Actinobacillus (Haemophilus) pleuropneumoniae, Pasteurella multocidaand/or Streptococcus suis.
In horses, ceftiofur is active against the following microorganisms, found in respiratory-tract infections: Streptococcusspp (including Streptococcus zooepidermicus and Streptococcus equi), Staphylococcusspp, Pasteurellaspp.
Cell wall synthesis is dependent on enzymes that are called penicillin-binding proteins (PBP's). Bacteria develop resistance to cephalosporins by four basic mechanisms: 1) altering or acquiring penicillin binding proteins insensitive to an otherwise effective b-lactam; 2) altering the permeability of the cell to b-lactams; 3) producing b-lactamases that cleave the b-lactam ring of the molecule, or 4) active efflux.
The following ceftiofur breakpoints are used: 2 µg/mL (Susceptible), 4 µg/mL (Intermediate) and 8 µg/mL (Resistant).
The following Minimum Inhibitory Concentrations (MIC) have been determined for ceftiofur in European isolates (France, United Kingdom, Netherlands, Denmark, Germany, Belgium, Italy, Czech Republic, Ireland, Poland and Spain) collected from diseased animals between 2000 to 2007:

5.2 Pharmacokinetic particulars
After intramuscular administration ceftiofur is quickly metabolised to desfuroylceftiofur which reaches maximum plasma concentration within 1 hour. The plasma half-life for desfuroylceftiofur is on average over 9 hours in cattle and 13 hours in pigs. No accumulation has been shown after several administrations.
