Tiamulin is a pleuromutilin antibiotic drug that is used in veterinary medicine particularly for pigs and poultry. Tiamulin is a diterpene antimicrobial with a pleuromutilin chemical structure similar to that of valnemulin. It acts by binding to the bacterial 50S ribosomal subunit at the peptidyl transferase center, thereby inhibiting protein synthesis; this binding site and mechanism explain its activity against mycoplasmas, certain Gram positive bacteria and anaerobes, and spirochetes such as Brachyspira species. Chemically it contains the characteristic mutilin tricyclic core with a thioether-linked side chain that modulates spectrum and pharmacokinetic properties. In veterinary practice tiamulin is formulated as the free base or as salts and is administered orally in feed or water; it is well absorbed in target species, shows distribution to lung and intestinal tissues, and undergoes hepatic metabolism with elimination primarily in bile and feces. Use considerations include species-specific dosing, potential drug interactions with ion transport inhibitors and macrolides, and adherence to withdrawal times to avoid residues in edible tissues.

Tiamulin is used as a veterinary antibiotic to treat and control infections caused by susceptible organisms, especially mycoplasmas, certain Gram positive bacteria and anaerobes, and spirochetes in food-producing animals; typical uses include control of mycoplasmal respiratory disease and enteric infections in pigs and poultry, and targeted treatment of swine dysentery and other bacterial enteropathies when indicated.
In chickens tiamulin is primarily used to treat mycoplasmosis caused by Mycoplasma gallisepticum and Mycoplasma synoviae and to control certain enteric infections and spirochetal diseases such as those caused by Brachyspira species; it is administered via feed or water at veterinarians recommended doses and requires attention to withdrawal periods for meat.
In pigs tiamulin is commonly used to treat and control swine dysentery caused by Brachyspira hyodysenteriae, porcine mycoplasmosis including Mycoplasma hyopneumoniae associated respiratory disease, and selected enteric infections such as those involving Lawsonia intracellularis in some treatment protocols; dosing and duration are adjusted to the condition being treated and farm management practices.
Tiamulin is generally considered bacteriostatic because it inhibits bacterial protein synthesis by binding the 50S ribosomal subunit, but bactericidal activity can be observed against highly susceptible organisms or at sufficiently high concentrations in vitro; clinical outcome depends on pathogen susceptibility, drug exposure at the infection site, and host factors.
