Pharmacological properties

4.1 ATCvet code: QG51AA05.

4.2 Pharmacodynamics

Cefapirin, a first generation cephalosporin, is a broad spectrum antibiotic with bactericidal action against gram-positive and gram-negative bacteria. Cefapirin is resistant to the action of penicillinase.

4.3 Pharmacokinetics

After intrauterine treatment systemic absorption is low, which is reflected by the low plasma levels of cefapirin observed shortly after treatment. Twelve hours after treatment, cefapirin levels in plasma are below detectable levels.

After intrauterine administration of the veterinary medicinal product, high cefapirin concentrations are observed in the endometrium.

Cefapirin concentrations in the endometrium can be observed for up to 24 hours.

3

Target species

Cattle (cows).

3

Indications

The veterinary medicinal product is indicated for the treatment of subacute and chronic endometritis in cows (at least 14 days after parturition) caused by bacteria sensitive to cefapirin.

3

Dosage

Intrauterine use.

The contents of one syringe should be introduced into the lumen of the uterus using the disposable catheter provided as follows:

1. Shake the syringe before use.

2. Fix the syringe to the catheter.

3. Hold the cervix of the uterus with one gloved hand introduced into the rectum.

4. Introduce the catheter through the cervix into the lumen of the uterus, by gentle oscillating movements of the cervix.

5. Inject the contents of the syringe.

Depending on the response, a second treatment 7-14 days later may be required in some cases if clinical signs persist.

In animals that have been inseminated, the veterinary medicinal product may be used at one day after insemination. In cases of pyometra, pre-treatment with prostaglandin is recommended in order to induce luteolysis and remove debris from the uterine cavity.

3

Contraindications

Do not use in cases of hypersensitivity to cephalosporins or other beta-lactam antibiotics.

Warnings

Special precautions for safe use in the target species:

Use of the product should be based on identification and susceptibility testing of the target pathogen(s). If this is not possible, therapy should be based on epidemiological information and knowledge of susceptibility of the target pathogens at farm level, or at local/regional level.

Use of the product should be in accordance with official, national and regional antimicrobial policies.

An antibiotic with a lower risk of antimicrobial resistance selection (lower AMEG category) should be used for first line treatment where susceptibility testing suggests the likely efficacy of this approach.

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 are occasionally serious.

People with known hypersensitivity to penicillins and cephalosporins should avoid contact with the veterinary medicinal product.

Do not handle this veterinary medicinal product if you know you are sensitised or if you have been advised not to work with such preparations.

Handle this veterinary medicinal product with great care to avoid exposure, taking all recommended precautions.

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 or eyes or difficulty breathing are more serious symptoms and require urgent medical attention.

Accidental spillage on the skin should be washed off immediately with soap and water. Wash hands after use.

Special precautions for the protection of the environment:
