4 CLINICAL PARTICULARS
4.1 Target species
Cattle, sheep, pigs, cats and dogs.
4.2 Indications for use, specifying the target species
The product is suitable for the control of infections, due to susceptible micro-organisms, in cattle, pigs, sheep, dogs and cats where a single injection giving prolonged antibiotic cover is required. It may also protect from secondary bacterial invasion in cases where bacteria are not the initial cause of the disease.
Indications include infections of:
Alimentary tract, Respiratory tract, Skin and soft tissue
Urogenital tract and in prevention of post-operative infection (treat before surgery).
In vitroamoxicillin is effective against a wide range of Gram-positive and Gram-negative bacteria which include:
Escherichia coli, Klebsiella pneumonia, Proteusspp.,Salmonella spp. staphylococci and streptococci.
This product is not suitable for administration via intravenous or intrathecal routes.
Not to be administered to animals sensitive to penicillin.
Not to be used in rabbits, guinea pigs, hamsters, gerbils or in any other small herbivores.
Not effective against beta-lactamase producing organisms.
4.4 Special warning for each target species
Not to be used in animals with previous sensitivity to penicillins.
4.5 Special precautions for use
(i) Special precautions for use in animals
(ii) Special precautions to be taken by the person administering the medicinal product to the animals
Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillins may cause cross
reactions to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.
1) Do not handle this product if you know you are sensitised, or if you have been advised not to work with such preparations.
2) Handle this product with great care to avoid exposure, taking all recommended precautions.
3) 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)
Occasional local tissue reaction may result from use of this product.
4.7 Use during pregnancy, lactation or lay
No special precautions necessary.
4.8 Interaction with other medicinal products and other forms of interaction
Amoxicillin exerts its bactericidal action by inhibition of bacterial cell wall synthesis during multiplication. It is therefore in principle not compatible with bacteriostatic antibiotics (tetracyclines, chloramphenicol) which inhibit multiplication. Synergism occurs with ß-lactam antibiotics and aminoglycosides.
4.9 Amounts to be administered and administration route
Dosage: in general 15 mg/kg/bodyweight (equivalent to 1 ml per 10 kg bodyweight), repeated if necessary after 48 hours.
A separate injection site should be used for each administration.
Suggested doses are:
Cattle 500 kg - 50 ml
Sheep 50 kg - 5 ml
Pigs 50 kg - 5 ml
Dogs 10 kg - 1 ml
Cats 5 kg - 0.5 ml
Administration:Cattle, sheep and pigs - by intramuscular injection only. Dogs and cats - intramuscular or subcutaneous injection. An appropriately graduated syringe must be used to ensure accurate administration of the required dose volume. This is particularly important when injecting small volumes.
Shake the vial before use. This product does not contain antimicrobial preservative. Swab the septum before removing each dose. Use a dry, sterile needle and syringe. After administration massage the injection site. Dose volumes in excess of 20ml should be injected at more than one site.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Amoxicillin is a compound with a very high therapeutic ratio. It is very unlikely that an overdose of Amoxypen LA will have adverse effects on the treated animal.
4.11 Withdrawal periods for the various foodstuffs, including those for which the withdrawal period is zero
Milk for human consumption must not be taken from a cow during treatment.
With cows milked twice daily, milk for human consumption may only be taken from 79 hours (i.e. at the 7thmilking) after the last treatment. With other dosing routines, the basis of the veterinary surgeon’s advice should be that milk may be taken for human consumption only after the same time period from the last treatment (i.e. with three times a day milking, milk for human consumption may only be taken at the 10thmilking).
Not for use in sheep producing milk for human consumption.
Animals must not be slaughtered for human consumption during treatment. Cattle may be slaughtered for human consumption only after 23 days from the last treatment.
Sheep and pigs may be slaughtered for human consumption only after 16 days from the last treatment.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
The active ingredient, amoxicillin, is a bactericidal antibiotic of the ß-lactam class which acts by inhibition of bacterial cell wall synthesis. Amoxicillin is not resistant to the action of beta-lactamases which can hydrolyse the molecules causing the beta-lactam ring structure to open, rendering it antibiotically inactive.
Due to its wide distribution after absorption, high levels of amoxicillin are found in kidney, urine, liver and bile.
ATC Vet Code: QJ01CA04
5.2 Pharmacokinetic particulars
Following intramuscular injection in cattle at the recommended dosage rate peak levels were observed 2.98 hours following administration
Following intramuscular injection in sheep at the recommended dosage rate peak levels were observed 0.96hours following administration
Following intramuscular injection in pigs at the recommended dosage rate peak levels were observed 1.18 hours following administration.
