Excipients:

For the full list of excipients, see section 6.1.

3. PHARMACEUTICAL FORM

Tablets.

Light brownish yellow, capsule shaped, biconvex, marble tablets with possible dark and white spots and scored on the both sides. The tablets can be divided into halves.

4. CLINICAL PARTICULARS

4.1 Target species

Dogs.

4.2 Indications for use, specifying the target species

Treatment of infections caused by strains of microorganisms susceptible to marbofloxacin in dogs:

- skin and soft tissue infections (skinfold pyoderma, impetigo, folliculitis, furunculosis, cellulitis);

- urinary tract infections (UTI) associated or not with prostatitis or epididymitis;

- respiratory tract infections.

4.3 Contraindications

Do not use in dogs aged less than 12 months, or less than 18 months for exceptionally large breeds of dogs, such as Great Danes, Briard, Bernese, Bouvier and Mastiffs, with a longer growth period.

Do not use in cats. For the treatment of this species, a 5 mg tablet is available. Do not use in cases of hypersensitivity to marbofloxacin or other (fluoro)quinolones or to any of the excipients.

Do not use in cases of resistance against quinolones, since (almost) complete crossresistance exists against other fluoroquinolones.

4.4 Special warnings for each target species

A low urinary pH could have an inhibitory effect on the activity of marbofloxacin. Pyoderma occurs mostly secondary to an underlying disease, thus, it is advisable to determine the underlying cause and to treat the animal accordingly.

4.5 Special precautions for use

Special precautions for use in animals

High doses of some fluoroquinolones may have epileptogenic potential. Cautious use is recommended in dogs diagnosed as suffering from epilepsy. However, at the therapeutic recommended dosage, no severe side-effects are to be expected in dogs. Fluoroquinolones have been shown to induce erosion of articular cartilage in juvenile dogs and care should be taken to dose accurately especially in young animals. At the recommended dose rate, no lesions of the articular joints were encountered in clinical studies.

Official and local antimicrobial policies should be taken in to account when the veterinary medicinal product is used. Fluoroquinolones should be reserved for the treatment of clinical conditions which have responded poorly, or are expected to respond poorly to other classes of antimicrobials. Whenever possible, use of fluoroquinolones should be based on susceptibility testing. Use of the product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to the (fluoro)quinolones and may decrease effectiveness of treatment with other quinolones due to the potential for cross-resistance.

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

People with known hypersensitivity to (fluoro)quinolones should avoid contact with the veterinary medicinal product.

In case of accidental ingestion seek medical advice immediately and show the package leaflet or the label to the physician. Wash hands after use.

4.6 Adverse reactions (frequency and seriousness)

Mild side effects such as vomiting, softening of faeces, modification of thirst or transient increase in activity may very rarely occur. These signs cease spontaneously after treatment and do not necessitate cessation of treatment.

The frequency of adverse reactions is defined using the following convention:

- very common (more than 1 in 10 animals treated displaying adverse reaction(s))

- common (more than 1 but less than 10 animals in 100 animals treated)

- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

- rare (more than 1 but less than 10 animals in 10,000 animals treated)

- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

4.7 Use during pregnancy, lactation or lay

Studies in laboratory animals (rat, rabbit) showed no embryotoxicity, teratogenicity and maternotoxicity with marbofloxacin at therapeutic doses.

The safety of marbofloxacin has not been assessed in pregnant and lactating dogs. Use only according to the benefit/risk assessment by the responsible veterinarian in pregnant and lactating animals.

4.8 Interaction with other medicinal products and other forms of interaction

Fluoroquinolones are known to interact with orally administered cations (Aluminium, Calcium, Magnesium, Iron). In such cases, the bioavailability of marbofloxacin may be reduced. Concurrent administration of theophylline products may be followed by inhibited theophylline clearance.

4.9 Amounts to be administered and administration route

For oral administration.

The recommended dose rate is 2 mg marbofloxacin/kg body weight/day (1 tablet for 40 kg body weight per day) in single daily administration. Where appropriate, the use of combinations of whole or half tablets of different strengths (80 mg, 20 mg or 5 mg) will allow accurate dosing :

Animal body weight (kg)	Number of tablets (80 mg + 20 mg strengths)	Approx. dosage range (mg/kg)
17 – 20	0.5	2.0 – 2.4
>20 – 25	0.5 + 0.5	2.0 – 2.5
>25 – 30	0.5 + 1	2.0 – 2.4
>30 – 40	1	2.0 – 2.7
>40 – 50	1 + 1	2.0 – 2.5
>50	1.5	≤2.4

To ensure a correct dosage body weight should be determined as accurately as possible to avoid underdosing.

Duration of treatment:

- in skin and soft tissue infections, treatment duration is at least 5 days and depending on the course of the disease, it may be extended up to 40 days.

- in urinary tract infections, treatment duration is at least 10 days and depending on the course of the disease, it may be extended up to 28 days.

- in respiratory infections, treatment duration is at least 7 days and depending on the course of the disease, it may be extended up to 21 days.

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

Overdosage may cause acute signs in the form of neurological disorders, which should be treated symptomatically.

4.11 Withdrawal period(s)

Not applicable.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Antibacterials for systemic use, Fluoroquinolones, ATCvet code: QJ01MA93

5.1 Pharmacodynamic properties

Marbofloxacin is a synthetic, bactericidal antimicrobial, belonging to the

fluoroquinolone group which acts by inhibition of DNA gyrase and of topoisomerase

IV. It is effective against a wide range of Gram-positive bacteria (including streptococci and in particular staphylococci,) and Gram-negative bacteria (Escherichia coli, Citrobacter freundii, Proteus spp., Klebsiella spp., Shigella spp., Pasteurella spp., Pseudomonas spp.) as well asMycoplasma spp.

A secondary literature report of microbiological susceptibility data whose source included two European field surveys, each involving hundreds of canine and feline pathogens susceptible to marbofloxacin, was published in 2014.

Microorganism	MIC50 (µg/ml)
Staphylococcus intermedius	0.250
Escherichia coli	0.030
Pasteurella multocida	0.030
Pseudomonas aeruginosa	0.500

Susceptibility break points have been determined as ≤1 µg/ml for sensitive, 2 µg/ml for intermediate and ≥4 µg/ml for resistant bacterial strains.

Marbofloxacin is not active against anaerobes, yeast or fungi. Cases of resistance have been observed in Streptococcus. Resistance to fluoroquinolones occurs by chromosomal mutations leading to decrease of the bacterial cell wall permeability, expression change of efflux pumps or changes of primary structure of target enzymes responsible for molecule binding. In some Gram-negative bacteria, plasmidmediated quinolone resistance has been reported.

5.2 Pharmacokinetic particulars

After oral administration in dogs at the recommended dose of 2 mg/kg body weight, marbofloxacin is readily absorbed and reaches maximal plasma concentrations of 1.5 µg/ml within 2 hours.

Its bioavailability is close to 100%.

It is weakly bound to plasma proteins (less than 10%), extensively distributed and in most tissues (liver, kidney, skin, lung, bladder, digestive tract) it achieves higher concentrations than in plasma. Marbofloxacin is eliminated slowly (t½ß = 14 h in dogs) predominantly in the active form in urine (2/3) and faeces (1/3).
