Tiamulin Fumarate


Tiamulin is active against gram-positive bacteria, mycoplasmas, and anaerobes, including Brachyspira hyodysenteriae. It is also clinically effective in the treatment of swine dysentery and mycoplasmal arthritis. Tiamulin is well absorbed when administered PO. The dosage is 8.8 mg/kg, sid for 3–5 days, in either food or water. The parenteral dosage for mycoplasmal pneumonia in pigs is 15 mg/kg. In poultry, tiamulin interferes with monensin and salinomycin metabolism, and if the drugs are fed together, they become toxic. Generally, however, tiamulin has few side effects.
