Tylvalosin, sold under the brand name Aivlosin, is a macrolide antibiotic used for the treatment of bacterial infections with Mycoplasma hyopneumoniae in swine, that causes enzootic pneumonia.

[3] Macrolides are generally considered to be bacteriostatic agents that exert their antibiotic effect by reversibly binding to the 23S rRNA of the 50S ribosomal subunit, thereby inhibiting bacterial protein synthesis.

[7] Tylvalosin is indicated for the control of porcine proliferative enteropathy associated with Lawsonia intracellularis infection in groups of swine intended for slaughter and female swine intended for breeding in buildings experiencing an outbreak of PPE.
