4.3 Contraindications

Not to be administered to animals which are known to be hypersensitive to cephalosporin antibiotics and other β-lactam antibiotics.

Please refer to section 4.7

4.4 Special warnings

None.

4.5 Special precautions for use

Special precautions for use in animals

Do not bend the nozzle.

Do not contaminate the nozzle.

Use of the product should be based on susceptibility testing and should take into account official and local antimicrobial policies. Increased use, including use of the product deviating from the instructions given in the SPC, may increase the prevalence of bacteria resistant to cefalonium.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Wash hands after use.

Penicillin and cephalosporins may cause sensitisation (allergy) following injection, inhalation, ingestion or skin contact. Sensitivity to penicillin may lead to cross-sensitivity to cephalosporin 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 breathing difficulties are more serious symptoms and require urgent medical attention.

4..6 Adverse reactions (frequency and seriousness)

None known

4.7 Use during pregnancy, lactation or lay

Intended for use during the last trimester of pregnancy once the lactating cow has been dried off. There is no adverse treatment effect on the foetus.

Not to be used in lactating cows.

4.8 Interaction with other medicinal products and other forms of interaction

None known.

4.9 Amounts to be administered and administration route

For intramammary use.

The content of one syringe should be infused into the teat canal of each quarter immediately after the last milking of the lactation. Before infusion, the teat should be thoroughly cleaned and disinfected with the cleaning towel provided. Avoid contamination of the nozzle after removing the cap.

Option 1: For short nozzle intramammary administration:hold the barrel of the syringe and the base of the cap in one hand and twist off the small upper part of the cap above the indent mark (the base portion of the cap remains on the syringe). Take care not to contaminate the short exposed part of the nozzle.

Option 2: For full nozzle intramammary administration:remove the cap fully by holding the barrel of the syringe firmly in one hand and with the thumb push up and along the length of the cap until the cap clicks off. Take care not to contaminate the nozzle.

Insert the nozzle into the teat canal and apply steady pressure on the syringe plunger until the full dose has been delivered. Holding the end of the teat with one hand, gently massage upwards with the other to aid dispersion of the antibiotic into the quarter.

Finally immerse the teats in a teat dip.

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

Repeated doses in cattle on three consecutive days did not demonstrate or produce any adverse effects.

4.11 Withdrawal period(s)

Meat and offal:

21 days

Milk:

• Interval treatment-calving ≥ 54 days: withdrawal period = 96 hours after calving.

• Interval treatment-calving < 54 days: withdrawal period = 54 days plus 96 hours after treatment, ensuring that at least 7 complete milkings are discarded.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Cephalosporins and related substances

ATCvet code: QJ51DB90

5.1 Pharmacodynamic properties

The product is a long-acting intramammary suspension containing cefalonium dihydrate, a semi-synthetic cephalosporin antibiotic. It is formulated to give persistent antibiotic levels in the dry udder.

Cefalonium is an antibacterial drug of the cephalosporin group which acts by inhibition of cell wall synthesis (bactericidal mode of action). It is characterised by its broad therapeutic spectrum of activity and a high stability against beta-lactamases.

Cefalonium is active against: Corynebacterium bovis, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, Escherichia coli, Klebsiella spp. and Arcanobacterium pyogenes.

MIC data was generated for Gram-positive and Gram-negative isolates over the period 2000 to 2006. Particular regard was paid to the following mastitis pathogens: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, Escherichia coli, Klebsiella spp. and Arcanobacterium pyogenes.An overview of the MIC₉₀ valuesof these bacterial mastitis pathogens is presented in the table below:

Table 1: Summary of susceptibility data for cefalonium against mastitis isolates from the period 2000 to 2006

Organism	Year of Isolation	n	MIC range (µg/mL)	MIC90 (µg/mL)
Staphylococcus aureus	2000 – 2006	120	≤0.03 – 0.125	0.125
Streptococcus agalactiae	2004 - 2005	11	0.0078 – 0.0156	0.0156
Streptococcus dysgalactiae	2000 - 2006	123	0.00375 – 0.06	0.0078
Streptococcus uberis	2000 - 2005	120	0.00375 – 0.125	0.06
Arcanobacterium pyogenes	2000 - 2006	38	0.03 – 0.125	0.125
Escherichia coli	2000 – 2006	64	0.5 – 4	2
Klebsiella spp.	2000 – 2006	64	1 - 4	2

. Cattle treated with Cepravin Dry Cow have lower somatic cell counts after calving.

5.2 Pharmacokinetic particulars

Pharmacokinetics of cefalonium in the target species has been investigated following intramammary administration in several studies. The presence of cefalonium and/or its biologically active metabolites was detected in urine and serum.

Cefalonium is extensively but slowly absorbed from the udder and excreted primarily in the urine. Between 7 and 13% of the active substance is eliminated in urine on each of the first three days post dosing whilst daily excretion in faeces is < 1% over the same period.

Mean blood concentration remains fairly constant during approximately 10 days after dosing which is consistent with slow but prolonged absorption of cefalonium from the udder.

The long term persistence of cefalonium in the dry udder was examined over a time span of 10 weeks after infusion. Efficient levels of cefalonium in udder secreta remained up to 10 weeks after infusion.
