Indications for use, specifying the target species
Forthe treatmentofbacterialbronchopneumonia caused byenrofloxacin-sensitive Actinobacillus pleuropneumoniae, Pasteurella multocida and complicated byHaemophilus parasuisas secondary pathogen in pigs.
Do notuse in case ofhypersensitivityto the active substance orto anyofthe excipients. Do notuse in case ofresistance againstotherfluoroquinolone due to the potentialforcross-resistance.
Do notuse in animals with centralnervous system-associated seizure disorders. Do notuse in the presence ofexistingdisorders ofcartilage developmentormusculoskeletaldamage around functionallysignificantorweight-bearingjoints. Do notuse for prophylaxis.
Special warnings for each target species
Special precautions for use
Special precautions for use in animals
Repeated injections should be administered atdifferentsites.
Official, nationaland regionalantimicrobialpolicies should be taken into accountwhen the productis used.
Fluoroquinolones should be reserved forthe treatmentofclinicalconditions which have responded
poorly, orare expected to respond poorly, to otherclasses ofantimicrobials.
Wheneverpossible, fluoroquinolones should onlybe used based on susceptibilitytesting.
Use ofthe productdeviatingfromthe instructions given in the SPCmayincrease the prevalence of bacteria resistantto the fluoroquinolones and maydecrease the effectiveness oftreatmentwith other quinolones due to the potentialforcross resistance.
Enrofloxacin is eliminated renally. As with allfluoroquinolones, delayed excretion can therefore be expected in the presence ofexistingrenaldamage.
Specialprecautions to be taken bythe person administeringthe veterinarymedicinalproducttoanimals
People with known hypersensitivityto (fluoro)quinolones should avoid contactwith the veterinary medicinalproduct.
Directcontact with the skin should be avoided due to sensitisation, contactdermatitis and possible hypersensitivityreactions.
Wash anysplashes fromskin oreyes immediatelywith water. Do noteat, drinkorsmoke while handlingthe product.
Take care to avoid accidentalself-injection. In case ofaccidentalself-injection, seekmedicaladvice immediatelyand showthe package leafletorlabelto the physician.
Adverse reactions (frequency and seriousness)
In rare cases, transitoryinflammatoryreactions (swelling, redness)can occuratthe injection site. These regress within a fewdays withoutfurthertherapeutic measures.
The frequencyofadverse reactions is defined usingthe followingconvention:
very common (more than 1 in 10 animals displaying adverse reactions during the course of one treatment)
common (more than 1 but less than 10 animals in 100 animals)
uncommon (more than 1 but less than 10 animals in 1,000 animals)
rare (more than 1 but less than 10 animals in 10,000 animals)
very rare (less than 1 animal in 10,000 animals, including isolated reports)
Use during pregnancy, lactation or lay
Maybe used duringpregnancyand lactation.
Interaction with other medicinal products and other forms of interaction
Antagonisteffectsduetoconcurrentadministrationofbacteriostaticantimicrobialagentssuchas macrolides ortetracyclines and phenicols macrolides and tetracyclines mayoccur.
Enrofloxacin mayinterfere with the metabolismoftheophylline, decreasingtheophylline clearance resultingin increased plasma levels oftheophylline
Amounts to be administered and administration route
The dosage forrespiratorytractinfections is 7.5mgenrofloxacin perkgbodyweightfora single administration.
This corresponds to
0.75 ml Baytril 1nject solution for injection per 10 kg body weight per day
No more than 7.5 mlshould be administered atanyone injection site. In cases ofsevere orchronic respiratorytractinfections, a second injection maybe required after48 hours.
The intramuscularinjection should be made into the neckatthe earbase. Repeated injections should be made atdifferentinjection sites.
To ensure administration ofthe correctdosage, bodyweightshould be determined as accuratelyas possible to avoid underdosing. The stoppermaybe safelypunctured up to 20 times.
Overdose (symptoms, emergency procedures, antidotes), if necessary
Doses ofaround 25 mgactive ingredientperkgbodyweightand above maycause lethargy, loss of appetite and ataxia.No information is available on the tolerabilityofdoses severaltimes higherthan the therapeutic dose (overthe recommended ora prolonged treatmentperiod).
Do notexceed the recommended dose. In accidentaloverdose there is no antidote and treatment
should be symptomatic.
Meatand offal: 12 days
Pharmacotherapeutic group: antibacterials forsystemic use,Fluoroquinolones, ATCvetcode:QJ01MA90
Enrofloxacin has a spectrumofactivitywhich includesActinobacillus pleuropneumoniae, Pasteurella multocida and Haemophilus parasuis.
Enrofloxacin belongs to the fluoroquinolone group ofantibiotics. The substance has bactericidal activitywhich is mediated bybindingto subunitAofDNAgyrase and the resultingselective inhibition ofthis enzyme.
DNAgyrase is a topoisomerase. These enzymes are involved in the replication, transcriptionand recombination ofbacterialDNA. Fluoroquinolones also influence bacteria in the stationaryphase by alteringcellwallpermeability.
Resistance to fluoroquinolones has been reported to arise fromfive sources, (i)pointmutations in the
genes encodingforDNAgyrase and/ortopoisomerase IVleadingto alterations ofthe respective enzyme, (ii)alterations ofdrugpermeabilityin Gram-negative bacteria, (iii)efflux mechanisms, (iv) plasmid mediated resistance and (v)gyrase protectingproteins. Allmechanisms lead to a reduced susceptibilityofthe bacteria to fluoroquinolones. Cross-resistance within the fluoroquinolone class of antimicrobials is common.
The inhibitoryand bactericidalconcentrations ofenrofloxacin are veryclose, beingeitheridenticalor differingbyno more than 1-2 dilution steps.
Followingintramuscularadministration in pigs, the active ingredientenrofloxacin is absorbed very rapidlyand almostcompletely(high bioavailability). Peakserumconcentrations ofthe active ingredientare reached after1-2 hours.
Therapeutic concentrations are maintained fora period ofatleast48 hours.
Enrofloxacin has a high volume ofdistribution. The concentrations in the tissues and organs mostly significantlyexceed serumlevels. Organs in which high concentrations can be expected include the lungs, liver, kidneys, gutand muscle tissue.
Enrofloxacin is eliminated renally.
