Tilmicosin (phosphate)

Tilmicosin (LY-177370) phosphate is an orally active calcium channel antagonist and macrolide antibiotic with antimicrobial activity. Tilmicosin phosphate mainly acts on the 50S subunit of bacterial ribosomes, inhibiting protein synthesis. Tilmicosin phosphate is effective in the treatment of respiratory diseases in livestock such as cattle, sheep and pigs. In addition, Tilmicosin phosphate has immunomodulatory and anti-inflammatory effects[1][2][3][4][5][6].
