3.4 Special warnings
None
3.5 Special precautions for use
Special precautions for safe use in the target species:
The choice of using amoxicillin should be based on bacterial susceptibility testing and take into account official, national and regional antimicrobial policies.
Use of the veterinary medicinal product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to amoxicillin and may decrease the effectiveness of treatment with amoxicillin due to the potential for cross-resistance.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Penicillin and cephalosporin may cause an allergic reaction following accidental injection, inhalation or absorption via the skin, which may be life threatening. Hypersensitivity to penicillin may lead to cross sensitivity to cephalosporins and vice versa. Avoid direct contact of the veterinary medicinal veterinary medicinal product with the skin or the mucosae.
Handle the product with great care to avoid exposure.
Wear gloves and wash hands after use of the veterinary medicinal product. In case of contact with the skin or eyes, wash immediately with water. Do not smoke, eat or drink during use of the veterinary medicinal product.
If you develop symptoms following exposure, such as a skin rash, seek medical advice immediately and show the package leaflet or the label to the physician. Swelling of the face, lips and eyes or difficulty with breathing are more serious symptoms and require urgent medical attention.
Special precautions for the protection of the environment:
Not applicable.

3.7 Use during pregnancy, lactation or lay
Pregancy and lactation:
Laboratory studies in rats and rabbits have not produced any evidence of teratogenic, foetotoxic or maternotoxic effects of amoxicillin. However, the tolerance of the veterinary medicinal product in cattle and pigs during pregnancy and lactation has not been investigated. In these cases, use only according to the benefit/risk assessment by the responsible veterinarian.
3.8 Interaction with other medicinal products and other forms of interaction
Do not use with antibiotics, which inhibit bacterial protein synthesis, as these can antagonise the bactericidal action of penicillins.

Intramuscular use.
Shake well before use.
15 mg amoxicillin per kg bodyweight; corresponding to 1 ml of the veterinary medicinal product per 10 kg.
Administration should be repeated after 48 hours.

4. PHARMACOLOGICAL INFORMATION
4.1 ATCvet code:
QJ01CA04
4.2 Pharmacodynamics
Amoxicillin is a broad-spectrum antibiotic of the amino-penicillin family with close structural relationship to ampicillin.
Amoxicillin is a bactericide and is active against Gram-positive and Gramnegative bacteria. It inhibits the synthesis and reparation of the bacterial mucopeptide cell wall.
Amoxicillin is a semisynthetic penicillin and susceptible to the action of bacterial beta- lactamases. Amoxicillin is a time-dependent antibiotic.
Amoxicillin is active against the following microorganisms which are involved in respiratory diseases in cattle: Mannheimia haemolytica and Pasteurella multocida. Amoxicillin is also active against Pasteurella multocida that is involved in respiratory diseases in pig.
The following Minimum Inhibitory Concentrations (MIC) have been determined for amoxicillin in European isolates (France, United Kingdom, Denmark, Germany, Italy, Czech Republic, and Spain) collected from diseased animals between 2009 to 2012:

The following amoxicillin breakpoints are recommended by the Comité de l'Antibiogramme of the Société Française de Microbiologie (SFM) : 4 µg/mL (Susceptible) and >16 µg/mL (Resistant).
Mechanism of action
The antimicrobial mechanism of action consists of the inhibition of the biochemical process of bacterial wall synthesis, through a selective and irreversible blockade of several enzymes, in particular transpeptidases, endopeptidases and carboxypeptidases. In susceptible bacteria, impairment of cell wall synthesis particularly during multiplication leads to lysis of the bacteria.
Bacteria which generally present resistance to amoxicillin are:
- Staphylococcus species producing penicillinase,
- Enterobacteria such as Klebsiella spp, Enterobacter spp, Proteus spp and
Pseudomonas aeruginosa.
Bacterial resistance towards amoxicillin is primarily mediated through ßlactamases which inactivate the antimicrobial by hydrolysis of the ß-lactam ring. Bacterial ß- lactamases can be codified in plasmids or in constituents of the bacterial chromosome.
These beta-lactamases are extracellular in Gram-positive bacteria (Staphylococcus aureus) whereas they are located in the periplasmic space in Gram-negative bacteria.
Gram-positive bacteria can produce beta-lactamases in large quantities. These enzymes are codified in plasmids, which can be transferred to other bacteria.
Gram-negative bacteria produce different types of beta-lactamases, which remain in the periplasmic space and which are codified in the chromosome or in the plasmid.
Complete cross resistance exists between amoxicillin and other penicillins, in particular other aminopenicillins.
4.3 Pharmacokinetics
In cattle Cmax (3.45µg/ml) is reached 2.45 hours after intramuscular administration. In pigs Cmax (3.54µg/ml) is reached 2 hours after intramuscular administration.
Amoxicillin is mainly distributed to the extra-cellular compartment. Its distribution into tissues is facilitated by its low degree of plasma protein binding (17%).
Concentrations in pulmonary, pleural and bronchial tissues are similar to plasma concentrations. Amoxicillin diffuses into pleural and synovial fluid and into lymphatic tissue.
Amoxicillin is biotransformed in the liver by hydrolysis of the ß-lactam ring leading to inactive penicilloic acid (20%). Amoxicillin is mainly excreted in active form via the kidneys, and secondarily by the biliary route and through milk.
