4. CLINICAL PARTICULARS


4.1 Target species


Cattle (lactating cows)


4.2 Indications for use, specifying the target species


Treatment of mastitis in lactating cows caused by Streptococcus uberis, Streptococcus dysgalactiae, Streptococcus agalactiaeand Staphylococcus aureus(beta-lactamase non-producing), sensitive to penicillin.


4.3 Contraindications

Do not use in animals known to be hypersensitive to penicillins, cephalosporins, and/or any of the excipients.

Do not administer intravenously.

Do not use in lagomorphs and rodents such as guinea pigs, hamsters or gerbils.

Do not administer to animals with renal disease including anuria or oliguria.


4.4 Special warnings for each target species


Treatment should be carried out during lactation.


4.5 Special precautions for use


This veterinary medicinal product does not contain any antimicrobial preservative.


Special precautions for use in animals


Using penethamate hydriodide for the treatment of mastitis must be accompanied by hygienic measures to prevent reinfection.

Where local (regional, farm-level), epidemiological information indicate possible reduced susceptibility of the relevant strains of the bacterial species involved in mastitis, use of the product should be based on susceptibility testing on bacteria isolated from diseased animals.

The veterinary medicinal product is not effective against beta-lactamase producing organisms.

Official national and regional antimicrobial policies should be taken into account when the product is used.

Use of the product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to benzylpenicillin and may decrease the effectiveness of treatment with other beta-lactam antimicrobials due to the potential for cross‑resistance.

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 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.


Wear gloves when handling the veterinary medicinal product to avoid contact sensitization.


In case of accidental self-injection or if you develop symptoms following exposure such as a skin rash, you should seek medical advice and show the package leaflet or the label to the doctor


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)


The symptoms of adverse reactions range from mild skin reactions such as urticaria and dermatitis to severe reactions such as anaphylactic shock with tremors, vomiting, salivation, gastrointestinal disorders and laryngeal oedema.


In some situations the treatment may lead to secondary infections due to overgrowth of non-target organisms.


4.7 Use during pregnancy, lactation or lay


Can be used during pregnancy and lactation.


4.8 Interaction with other medicinal products and other forms of interaction


The product should not be administered with antibiotics that have a bacteriostatic mode of action.


4.9 Amounts to be administered and administration route


Administer by deep intramuscular injection.

Directions for use: Reconstitute the suspension using the entire contents of the solvent vial.


To provide the correct dose:


Use the powder vial, which contains penethamate hydriodide 5,000,000 IU with the solvent vial, which contains 18 ml of a sterile solvent.

Or alternatively, use the powder vial, which contains penethamate hydriodide 10,000,000 IU with the solvent vial, which contains 36 ml of a sterile solvent.


Shake well after reconstitution. A minimum of 10 inversions of vials can be necessary.

Each ml of suspension contains 250,000 IU (236.3 mg) of penethamate hydriodide.


Dose: 15,000 IU (14.2 mg) of penethamate hydriodide per kg of body weight / day (equivalent to 6 ml of reconstituted medicinal product / 100 kg body weight) for three to four consecutive days. Shake well before use.


Administer the recommended daily dose every 24 hours, for three to four consecutive administrations.


To ensure administration of a correct dose, body weight should be determined as accurately as possible.


The recommended maximum volume to be administered at a single injection site is 20 ml.


The stopper should not be punctured more than 10 times.


4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary


In cases of overdose, adverse reactions such as those described in Section 4.6 may occur.


4.11 Withdrawal period(s)


Meat and offal: 4 days

Milk: 60 hours


5. PHARMACOLOGICAL PROPERTIES


Pharmacotherapeutic group: Antibacterials for systemic use, beta- lactam antibacterials, penicillins.

ATCvet code: QJ01CE90


5.1 Pharmacodynamic properties


The active substance, penethamate hydriodide, is a prodrug which releases benzylpenicillin. Chemically, it is a diethylaminoethanol ester of penicillin.

Mode of action:

Benzylpenicillin works by blocking the biosynthesis of the bacterial cell wall. Benzylpenicillin covalently attaches to and subsequently inactivates penicillin-binding proteins (PBPs), which are located on the inner surface of the bacterial membrane. The PBPs (transpeptidase, carbopeptidasas, endopeptidases) are enzymes involved in the terminal stages of bacterial cell-wall synthesis. Penicillins are only active against bacteria in the multiplication phase.


The antimicrobial spectrum of the active substance corresponds to that of benzylpenicillin which is effective against beta-lactamase negative Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis and Staphylococcus aureus.


Mechanisms of resistance:

The most frequent mechanism is producing beta-lactamases (more specifically penicillinase especially in S. aureus), which break the beta-lactam ring of penicillins making them inactive.


5.2 Pharmacokinetic particulars


Following intramuscular administration to dairy cows, Cmaxis rapidly achieved in blood and milk (3 and 7 hours respectively). Ninety percent of the antibiotic is hydrolysed in blood and 98% in milk. As a result of hydrolysis, diethylaminoethanol and benzylpenicillin are produced, with the latter being the therapeutically active molecule. The distribution is rapid within the organism, with particular affinity for lung and mammary gland tissues. It crosses the placenta and enters the foetal circulation slowly.
