• Pharmacological properties

    Tiamulin 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 antibiotic and the following organisms show sensitivity in vitro:

Brachyspira: Brachyspira hyodysenteriae, Brachyspira pilosicoli

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

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

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

    Following oral administration, tiamulin fumarate is rapidly absorbed and peak serum concentrations are achieved 2~4 hours after administration and concentrates in some tissues e.g. lung. Following absorption, it is rapidly metabolized and excreted.

• Indications

    For the treatment of chronic respiratory disease in chicken, the treatment, prevention and control of swine dysentery caused by Brachyspira hyodysenteriae and complicated by Fusobacterium and Bacteroides spp. As an aid in the control of the enzootic pneumonia complex in pigs.

• Usage and dosage

    Mix with feed or water:

    For pig: Every 1000kg feed, 40~100g Tiamulin fumarate, for 5~10 days consecutively.

    For Chicken: Every 1L water, 125~250mg Tiamulin fumarate, for 5 days consecutively.

• Withdrawal period: 7 days for pig; 5 days for chicken.
• Contra-indications

    Animals should not receive products containing monensin, narasin or salinomycin, during or for at least seven days before or after treatment with tiamulin.

    Shelf life: 5 years.
