Oral powder for medicated feeding stuff
A light brown free-flowing powder
Indications for use (specifying the target species)
For treatment and prevention of swine respiratory and digestive tracts infections sensitive to tiamulin (when the disease is present at individual level)
For individual application
Do not administer products containing ionophores such as monensin, salinomycin or narasin during or for at least seven days before or after treatment with the product.
See section 4.8.
Special warnings (for each target species)
The uptake of medication by animals can be altered as a consequence of illness..
Long term or repeated use should be avoided by improving management practice and thorough cleansing and disinfection.
Special precautions for use
Special precautions for use in animals
Do not use the product in liquid feed.
Use of the product should be based on susceptibility testing and take into account official and local antimicrobial policies.
Avoid concurrent administration of tiamulin and the ionophore products monensin, narasin and salinomycin (see section 4.8). Inform the feed supplier that tiamulin will be used, to avoid incorporating the above listed products in the feed and to avoid contamination of the feed. In case of a suspected contamination, test the feed for the presence of these ionophores before feeding. If adverse effects occur due to an interaction, stop administration of the feed immediately. Remove the contaminated feed as soon as possible and replace with uncontaminated feed.
Special precautions for the person administering the veterinary medicinal product to animals
Direct contact with the skin, eyes and mucous membranes should be avoided by wearing overalls, impermeable rubber gloves and safety glasses when mixing or handling the product.
In case of accidental eye contact, irrigate the eyes thoroughly with clean running water immediately. Seek medical advice if irritation persists.
When handling the product, inhalation of the dust must be avoided by wearing a disposable half-mask.
Accidental ingestion should be avoided.
Contaminated clothing should be removed and any splashes on to the skin should be washed off immediately.
Wash hands after use.
In case of accidental ingestion, seek medical advice immediately and show the package leaflet or label to the physician.
People with known hypersensitivity to tiamulin should handle the product carefully.
Adverse reactions (frequency and seriousness)
In rare cases, hypersensitivity to tiamulin following oral administration is reported in terms of acute dermatitis with cutaneous erythema and intense pruritus. The adverse reactions are usually mild and transient but in very rare cases may be serious. If these typical side effects occur, stop treatment immediately and clean animals and pens with water. Normally, affected animals recover quickly. Symptomatic treatment such as electrolyte therapy and an anti-inflammatory therapy may be useful.
Use during pregnancy, lactation or lay
The product can be used during pregnancy and lactation.
Interaction with other medicinal products and other forms of interaction
Tiamulin is known to produce clinically important (often lethal) interactions with ionophore antibiotics, including monensin, narasin, salinomycin. Therefore, pigs should not receive products containing such compounds during or for at least seven days before or after treatment with this product. Severe growth depression or death may result.
See also Section 4.3 and 4.5.1.
Tiamulin may lessen the antibacterial activity of beta-lactam antibiotics, whose action is dependent on bacterial growth.
Amount(s) to be administered and administration route
For oral administration only after incorporation in medicated feed.
For the treatment and prevention, when disease is confirmed at the herd level, of Treatment of swine dysentery:
1,0-1,5 kg premix per tonne of feed (equivalent to 100-150 g tiamulin/tonne) i.e. 100-150 ppm (5 – 7,5mg tiamulin/body weight) for 7-10 days
For treatment of enzootic pneumonia
10 mg tiamulin hydrogen fumarate per kg bodyweight per day for 7-10 consecutive days. This dose is obtained by mixing 2,0 kg of Premix per tonne of feed (200 ppm).
Overdose (symptoms, emergency procedures, antidotes), if necessary
Tiamulin hydrogen fumarate has a relatively high therapeutic index in pigs.
Meat and offal: 7 days
PHARMACOLOGICAL OR IMMUNOLOGICAL PROPERTIES
ATC Vet Code:
Pharmacotherapeutic group: antibacterials for systemic use, pleuromutilins
Tiamulin hydrogen fumarate is a semi-synthetic derivative of the diterpene antibiotic pleuromutilin, produced by Pleurotus mutilis.
Tiamulin is active against pathogenic mycoplasmas, against most Gram-positive organisms and Gram-negative organisms. Tiamulin is bacteriostatic and inhibits protein synthesis. The product has a strong affinity for the ribosome, causing an inhibition of peptidyltransferasis. As a result protein synthesis is stopped.
In vitro research has shown that resistant bacterial mutants can be created through multi step resistance. In practice, resistance in mycoplasmas has been reported rarely. Resistance against B. hyodysenteriae has been seen, however this spirochete remains very sensitive to tiamulin.
If response to treatment of dysentery with the product is poor, then the possibility of resistance must be considered. Cross resistance between tiamulin and tylosin has been reported.
Following oral administration, tiamulin hydrogen fumarate is rapidly absorbed from the gastrointestinal tract of pigs (85-90%) and appears in the blood within 30 minutes. 2-4 hours (tmax) after the oral administration of 10 mg tiamulin/kg BW in the form of an oral solution, a Cmax of 1 µg/ml was measured; an oral administration of 25 mg/kg gave a Cmax of 1.82 µg/ml.
There is very good distribution in the tissues with accumulation in lungs and in the colon. 30-50% of tiamulin is bound to serum proteins.
Tiamulin is rapidly metabolised in the liver (hydroxylation, de-alkalysation, hydrolysis). At least 16 biologically inactive metabolites have been identified. The excretion of tiamulin and its metabolites is through the bile and faeces (70-85%). The remainder is excreted through the urine (15-30%).
