Tylvalosin (tartrate)

Tylvalosin is a macrolide antibiotic. It is active against S. aureus, E. coli, and P. multocida (MICs = 2, 128, and 128 µg/ml, respectively). Tylvalosin (5 and 10 µg/ml) reduces LPS-induced production of pro-inflammatory cytokines, prostaglandin E2 (PGE2, Cay-14010), and nitric oxide in RAW 264.7 cells. It reduces the severity of lung lesions in pigs infected with M. hyopneumoniae and P. multocida when administered at a dose of 10 mg/kg per day in the drinking water. Formulations containing tylvalosin have been used in the treatment and metaphylaxis of enzootic pneumonia caused by M. hyopneumoniae in pigs.Formal Name: 3-acetate 4B-(3-methylbutanoate)tylosin, 2R,3R-dihydroxybutanedioate.
