5.1 Pharmacodynamic properties

Tiamulin hydrogen fumarate is a semi-synthetic diterpene antibiotic. The mode of action is by inhibition of ribosomal protein synthesis in sensitive bacteria. It is a bacteriostatic antimicrobial and the following organisms show sensitivity in-vitro:

Brachyspira: Brachyspira hyodysenteriae, B. pilosicoli.

Mycoplasmas: Mycoplasma hyopneumoniae, M. hyorhinis, M. hyosynoviae, Ureaplasma spp.

Gram-positive: Staphylococcus spp., Streptococcus spp., Arcanobacterium pyogenes.

Gram-negative: Pasteurella spp., Klebsiella pneumoniae, Actinobacillus (Haemophilus) spp., Fusobacterium necrophorum, Bacteroides spp., Campylobacter coli, Lawsonia intracellularis.

5.2 Pharmacokinetic particulars

Tiamulin is rapidly absorbed after oral administration. It concentrates in some tissues e.g. lungs and is rapidly metabolised an excreted.

Target species

Pigs.

3

Indications

Pigs: For the treatment, prevention and control of swine dysentery caused by Brachyspira hyodysenteriae and complicated by Fusobacterium and Bacteroides spp.

3

Dosage

Oral use. Administer in drinking water.

Pigs:

The dosage is 8.8 mg of the active substance per kg bodyweight daily, (equivalent to 10 ml solution per 142 kg bodyweight) administered in the drinking water of pigs for 3 to 5 days, depending on the severity of the infection and/or the duration of the disease.

To ensure an intake of 8.8 mg/kg daily it is important to know the weight of the animals to be treated and to measure accurately their drinking water consumption.

Administer the calculated dose (based on the animals weight) in approximately one half of the daily water requirements, to ensure consumption of the correct dose. Unmedicated water should then be provided each day after the medicated water has been consumed. The dosage rate, calculated on a liveweight basis, is equivalent to 10 ml solution per 142 kg bodyweight.

Where a water medicator is used the appropriate stock solution should be made up according to the makers instructions.

Any medicated water not consumed within 24 hours should be discarded.

If there is no response to treatment within 5 days, the diagnosis should be re- established.

Monitor water intake at frequent intervals during medication.

Fresh solutions of tiamulin-medicated drinking water should be made up each day.

3

Contraindications

Do not administer products containing monensin, salinomycin or narasin during or for at least 7 days before or after treatment. Severe growth depression or death may result.

3

Adverse reactions

3

Use during pregnancy, lactation or lay

The product can be used in pregnant and lactating pigs.

3

Interactions

See section 4.3, “Contraindications”.

3

Overdose

There is a relatively high therapeutic index with tiamulin and the likelihood of an overdosage is considered remote, especially as water intake and hence tiamulin intake is reduced if abnormally high concentrations are given.

If signs of intoxication do occur, promptly remove the medicated water and replace with fresh water.

3

Special warnings

In order to avoid interactions between tiamulin and the incompatible ionophores monensin, narasin and salinomycin, the feed mill supplying the feed should be

notified that tiamulin will be used and that these products should not be included in the feed or contaminate the feed.

The feed should be tested for the ionophores prior to use if there is any suspicion that contamination of the feed might occur. If an interaction does occur, stop tiamulin water medication immediately and replace with fresh water. Remove contaminated feed as soon as possible and replace with feed not containing the tiamulin-incompatible ionophores.
