White Solid | [Description]
Tulathromycin A is a triamide antibiotic used for the treatment of respiratory diseases in cattle and pigs. It exists as a balanced mixture of two isomers. Tulathromycin is an antimicrobial agent of a macrolide, a 15-membered macrolide structure that is considered a triamide macrolide with three charged nitro groups. | [Uses]
Triamilide antibiotic for treatment of bovine and porcine respiratory disease. Exists as an equilibrium mixture of two isomeric forms, Tulathromycin A (90%) and B (10%). Antibacterial. | [Uses]
Tulathromycin is a semi-synthetic erythromycin belonging to the ring expanded aza–erythromycins. Ring expansion improvedsthe acid lability of the parent erythromycins. Tulathromycin is regarded as the first of the triamilides, having a third amino (propylaminomethylene) group on a sugar to improve absorption. This modification provides a mixture of the two tulathromycin isomers (90:10) present in the commercial animal health product. | [Uses]
Tulathromycin is a semi-synthetic erythromycin belonging to the ring expanded aza–erythromycins. Ring expansion improves the acid lability compared with the parent erythromycins.

This modification provides a mixture of the two tulathromycin isomers (90:10) present in the commercial animal health product. | [Definition]
ChEBI:Tulathromycin A is an aminoglycoside. | [Biological Activity]
Tulathromycin, like other macrolides, exerts therapeutic benefits not solely explainable by antibacterial activity. Like azithromycin, tulathromycin A may have multiple immunomodulatory effects that likely contribute to the therapeutic response in respiratory infections and perhaps other diseases[1]. Other beneficial effects may be caused by enhanced degranulation and apoptosis of neutrophils and inhibition of inflammatory cytokine production. It also may help clear infections by enhancing macrophage functions. | [Pharmacokinetics]
The half-life is long, with 80- to 90-hour plasma half-life in pigs and cattle, and 8- and 6-day tissue half-life in cattle and pigs, respectively, which prolongs the drug concentration at the site of infection. The volume of distribution is greater than 10 L/kg. Absorption from injection is greater than 80% in cattle and pigs. Tulathromycin A concentrates in bronchoalveolar cells, and concentrations are detectable for at least 8 days after a single administration, although they are still lower than the MIC for R. equi (greater than 64 μg/mL)[1-2]. | [Mode of action]
Tulathromycin A is a macrolide antibiotic. It binds to the subunit 50S of the bacterial ribosome, interfering with bacterial protein synthesis. | [References]
