4. Clinical Particulars
4.1 Target species
Dogs
4.2 Indications for use, specifying the target species
Marbofloxacin is indicated in dogs for the treatment of:
Skin and soft tissue infections (skinfold pyoderma, impetigo, folliculitis, furunculosis, cellulitis) caused by susceptible strains of organisms,
Urinary tract infections associated or not with prostatitis caused by susceptible strains of organisms.
Respiratory infections, caused by susceptible strains of organisms.
4.3 Contraindications
Do not use in cats. A 5 mg tablet is available for the treatment of cats.
Do not use in animals with known hypersensitivity to marbofloxacin or other (fluoro)quinolones or to any of the excipients.
Do not use in dogs with central nervous system (CNS) disorders, such as epilepsy, as fluoroquinolones could potentially cause seizures in predisposed animals
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 as the fluoroquinolones have been shown to induce erosion of the articular cartilage in juvenile dogs.
4.4 Special Warnings for each target species
None.
4.5 Special precautions for use
Special precautions for use in animals
A low urinary pH could have an inhibitory effect on the activity of marbofloxacin.
Fluoroquinolones should only 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. Official and local antimicrobial policies should be taken into account when the veterinary medicinal product is used. Superficial and deep skin infections occurs mostly secondary to an underlying disease, thus, it is advisable to determine the underlying cause and to treat the animal accordingly Use of the product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to the fluoroquinolones 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 any contact with the veterinary medicinal product.
In case of accidental ingestion, seek medical advice immediately and show packaging or leaflet to the physician.
Wash hands after use.
4.6 Adverse reactions (frequency and seriousness)
Mild side-effects, such as vomiting, decreased or loss of appetite, softening of stools, thirst or a transient increase in activity may occasionally occur. The signs cease spontaneously after treatment and do not necessitate cessation of treatment.
Hypersensitive (allergic) reactions may occur in treated animals. In the case of allergic reaction, the treatment should be withdrawn.
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 the product has not been assessed in dogs during pregnancy and lactation. Use only accordingly to the benefit/risk assessment by the responsible veterinarian.
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 and Zinc). In such cases bioavailablity may be reduced. Marbofloxacin may antagonize nitrofurantoin, concomitant use is not recommended. Marbofloxacin may increase blood levels of methotrexate and theophylline, and alter phenytoin levels. The dose of Theophylline should be reduced in cases of concomitant administration. In case of glyburide therapy hypoglycemia may occur
4.9 Amounts to be administered and administration route
For oral administration.
The recommended dose rate is 2 mg/kg per day (1 tablet per 10 kg) in a single daily administration.
To ensure a correct dosage body weight should be determined as accurately as possible to avoid underdosing
In skin and soft tissue infections, treatment is at least 5 days but may be extended up to 40 days depending on the course of the disease.
In urinary infections, treatment is at least 10 days but may be extended up to 28 days depending on the course of the disease.
In resipiratory infections, treatment is at least 7 days but may be extended up to 21 days depending on the course of the disease.
The diagnosis should be re-evaluated before extending treatment beyond the minimum recommended treatment period

Overdose (symptoms, emergency procedures, antidotes), if necessary
Overdosage may cause cartilage damage in the joints and acute signs in the form of neurological disorders, tremors, which should be treated symptomatically.
Other signs of overdosage can include : anorexia, vomiting, dehydration, red skin, facial swelling, lethargy and weight loss
Bloody diarrhoea was observed at 3 times the recommended dose which resolved spontaneously without intervention
Withdrawal period
Not applicable.
5. pharmacological properties
Pharmacotherapeutic group: Antibacterials for systemic use; Fluoroquinolones
ATC Vet Code: QJ01MA93
5.1 Pharmacodynamic properties
Marbofloxacin, is a synthetic, bactericidal antimicrobial, belonging to the fluoroquinolone group which acts by inhibition of the DNA gyrase. Marbofloxacin is effective against a wide range of Gram positive bacteria (in particular Staphylococcus spp., Streptococci spp.) and Gram negative bacteria (Escherichia coli, Enterobacter cloacae, Serratia marcescens, Proteus spp., Klebsiella spp., Pasteurella spp., Pseudomonas spp.,) as well as Mycoplasma spp..
Resistance to fluoroquinolones occurs by chromosomal mutation leading to changes in three mechanisms that result in changes in the cell wall decreasing permeability, expression of an efflux pump or mutation in the enzymes reducing molecule binding. No significant evolution of resistance has been observed since the launch of marbofloxacin molecule on the veterinary market. The occurrence and rate of genetic transfer of resistance is therefore considered low.
Cross-resistance with β-lactam antibiotics, aminoglycoside, tetracyclines, macrolide and polypeptide antibiotics, sulfonamides, diaminopyrimidines and nitrofurans does not generally occur. However, certain mutation conferring resistance to fluoroquinolones can also confer cross resistance to cephalosporins, tetracylines, macrolides and chloramphenicol.
5.2 Pharmacokinetic properties
After oral administration in dogs at the recommended dose of 2 mg/kg, marbofloxacin is readily absorbed and reaches maximal plasma concentrations of 1.20 μg / ml within 2 hours.
Bioavailability of marbofloxacin is close to 100%. Marbofloxacin is weakly bound to plasma proteins and is extensively distributed. In most tissues, marbofloxacin is found at higher concentrations than in the plasma. Marbofloxacin is slowly eliminated from the body (t1/2β = 9.7 hours in dogs), predominantly in the active form, in urine and faeces.
