3. PHARMACEUTICAL FORM
Premix for medicated feeding stuff
4. CLINICAL PARTICULARS
4.1 Target species
4.2 Indications for use, specifying the target species
Treatment of bacterial enteritis caused by micro-organisms susceptible to apramycin such as Escherichia coli.
Do not use in the cases of hypersensitivity to apramycin
Do not use in cats
4.4 Special warnings
The uptake of medication by animals can be altered as a consequence of illness. In case of insufficient uptake of feed animals should be treated parenterally.
The use of the product should be combined with good management practices e.g. good hygiene, proper ventilation, no overstocking.
4.5 Special precautions for use
Special precautions for use in animals
Use of the product should be based on susceptibility testing and should take into account official national and regional policies.
Use of the product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to the apramycin and may decrease the effectiveness of treatment with aminoglycosides due to the potential for crossresistance
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Wash hands carefully with soap and water after handling of the product.
When handling this product, inhalation of the dust must be avoided by wearing a disposable half-mask respirator conforming to European Standard EN 149 or a non-disposable respirator to European Standard EN 140 with a filter to EN 143.
Avoid contact with skin and eyes. Gloves should be worn whilst handling this product. If contact with skin or eyes occurs, wash area immediately with clean fresh water. If irritation persists seek medical attention.
4.6 Adverse reactions (frequency and seriousness)
4.7 Use during pregnancy, lactation or lay
Laboratory studies have not produced any evidence of teratogenic, foetotoxic or maternotoxic effects.
The use is not recommended in pregnant or lactating sows.
4.8 Interaction with other medicinal products and other forms of interaction
4.9 Amounts to be administered and administration route
The recommended dose is 4 to 8 mg of apramycin per kg of body weight,.
This medicated feed should be given as sole ratio during at least 21 days.
It is recommended to mix the required quantity of the product with a small amount of feed (20 – 50 kg) before mixing it in the total volume.
The consumption of the medicated feed may depend of the clinical condition of the animals. In order to guarantee a correct dosing, the concentration of the productin the feed should be adjusted accordingly.
To adjust dosing properly following calculation can be used:
… mg product/kg b.w./day x average b.w. of pigs (kg)= … kg of the product/tone of feed
average daily intake of feed (kg/animal)
Medicated feed may be pelleted using a pre-conditioning step for 5 minutes at a temperature not exceeding 85°C.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
A single 100 fold overdosing in 5 pigs did not result in any mortality.
A 25 to 50 fold overdosing during 28 days, did not provoke any toxic effect.
4.11 Withdrawal period(s)
Meat and offal: 1 day
5. PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: apramycin.
ATCvet code: QA07AA92
5.1 Pharmacodynamic properties
aminoglycoside antibiotic apramycin binds to the 30S ribosomal
subunit and interferes with the protein synthesis. Through
mechanisms not yet completely elucidated, it acts on the cell wall
and is bactericidal. The overall spectrum includes many aerobic or
facultative anaerobic Gram-negative bacteria, including
Enterobacteriaceae. It has no activity against anaerobic bacteria
or under anaerobic conditions.
Susceptibility of theE. colistrains from pigs to apramycin can vary geographically and over time.
The most important mechanism of resistance against apramycin is the production of modifying enzymes that are usually encoded by resistance genes derived from plasmids. Depending on their spectrum, these enzymes may cause cross-resistance between aminoglycosides. Resistance may also be caused by a change of the ribosomal attachment sites, or the conveying system allowing the penetration of the cell.
Until harmonised international interpretative criteria relevant for susceptibility testing are available for apramycin, nationally approved and validated methods should be followed.
5.2 Pharmacokinetic particulars
Apramycinis very poorly absorbed orally. Tissue distribution is limited but nevertheless the best of all aminoglycosides.
Apramycin is excreted in its active form via the kidney.
