4. Clinical Particulars
4.1 Target species
Lactating cattle.
4.2 Indications for use, specifying the target species
Noroclav Lactating Cow Intramammary Suspension is specially formulated for the treatment of bovine mastitis. It has a notably broad spectrum of bactericidal activity against the bacteria commonly isolated from the bovine udder. The prednisolone in Noroclav Lactating Cow Intramammary Suspension has an anti-inflammatory action which helps to reduce the potentially destructive swelling and inflammation associated with mastitis, without affecting the white cell response to infection.
(i) In vitro Noroclav Lactating Cow Intramammary Suspension is active against a wide range of clinically important bacteria, including the following organisms, which are commonly associated with bovine mastitis:
Staphylococci (including beta-lactamase producing strains).
Streptococci (including S. agalactiae, S. dysgalactiae and S. uberis).
A. pyogenes and other minor members of the Corynebacteria spp.
Escherichia coli (including beta-lactamase producing strains).
In addition, it is active in vitro against many less common udder pathogens including:
Bacillus cereus, Bacteroides (including beta-lactamase producing strains), Campylobacter spp, Klebsiellae and Pasteurellae.
(ii) Clinically, Noroclav Lactating Cow Intramammary Suspension has been shown to be an effective, routine treatment for mastitis in lactating cows. Cases responding successfully to treatment include infections with the following major pathogens:
Staphylococci (including beta-lactamase producing strains).
Streptococci (including S. agalactiae, S. dysgalactiae and S. uberis).
Escherichia coli (including beta-lactamase producing strains).
4.3 Contraindications
Noroclav Lactating Cow Intramammary Suspension is contra-indicated in known cases of hypersensitivity to penicillins.
During the course of treatment the situation should be reviewed frequently by close veterinary supervision.
4.4 Special Warnings for each target species
None.
4.5 Special precautions for use
i Special precautions for use in animals
The product is not indicated for cases involving Pseudomonas species.
ii Special precautions to be taken by the person administering the veterinary medicinal product to animals
When infusing heifers, protective gloves should always be worn in order to avoid skin contact.
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 know 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)
None.
4.7 Use during pregnancy, lactation or lay
Noroclav Lactating Cow Intramammary Suspension is safe for use during pregnancy and lactation.
4.8 Interaction with other medicinal products and other forms of interaction
None known.
4.9 Amounts to be administered and administration route
Noroclav Lactating Cow Intramammary Suspension is suitable for intramammary administration to lactating cattle at a dose rate of 3 syringes per affected quarter administered singly at 12 hour intervals. Use each syringe only once. After milking, clean and disinfect the teat end thoroughly with surgical spirit. Insert the syringe nozzle into the teat orifice and apply gentle and continuous pressure until the suspension is expressed. The treated quarter(s) may be milked out at the next normal milking time, but the milk should be discarded.
Overdose (symptoms, emergency procedures, antidotes), if necessary
Not applicable.
Withdrawal period
Cattle (meat & offal): 7 days
(milk): 84 hours
5. pharmacological properties
Pharmacotherapeutic group: Antibacterial
ATC Vet Code: QJ51CR02
Pharmacodynamic properties
Amoxicillin is a beta-lactam antibiotic and its structure contains the beta-lactam ring and thiazolidine ring common to all penicillins. Amoxicillin shows excellent activity against susceptible Gram-positive bacteria and Gram-negative bacteria.
Beta-lactam antibiotics prevent the bacterial cell wall from forming by interfering with the final stage of peptidoglycan synthesis. They inhibit the activity of transpeptidase enzymes, which catalyse cross-linkage of the glycopeptide polymer units that form the cell wall. They exert a bactericidal action but cause lysis of growing cells only.
Clavulanic acid is one of the naturally occurring metabolites of the streptomycete Streptomyces clavuligerus. It has a structural similarity to the penicillin nucleus, including possession of a beta-lactam ring. Clavulanic acid is a beta-lactamase inhibitor acting initially competitively but ultimately irreversibly. Clavulanic acid will penetrate the bacterial cell wall binding to both extracellular and intracellular beta-lactamases.
Amoxicillin is susceptible to breakdown by -lactamase and therefore combination with an effective ß-lactamase inhibitor (clavulanic acid) extends the range of bacteria against which it is active to include -lactamase producing species.
Prednisolone is a corticosteroid of the glucocorticoid class. Prednisolone has significant anti-inflammatory properties. This anti-inflammatory action helps to reduce the swelling and inflammation associated with mastitis.
