> Applications
Tulathromycin is a long-acting triamilide macrolide antibiotic used by veterinary pharmaceutical companies and research groups working on respiratory-disease products for cattle and swine. API supply is intended for qualified buyers who will confirm species, withdrawal periods, indication language, finished-dose registration, and antimicrobial-use requirements in their own markets.
Swine respiratory disease formulation research
In a randomized study of pigs with respiratory disease caused by Actinobacillus pleuropneumoniae, 100 pigs were assigned to treatment groups receiving saline, tulathromycin doses, or ceftiofur (Veterinary Record, 2006, doi:10.1136/vr.158.13.433, n=100). The study supports Tulathromycin API relevance for veterinary macrolide formulation and research programs involving swine respiratory disease.
Bovine respiratory disease development
Tulathromycin is also associated with bovine respiratory disease programs involving Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and Mycoplasma bovis. Buyers typically evaluate assay, isomer profile, related substances, residual solvents, water content, antimicrobial potency, and stability data before moving from sample quantities to pilot or commercial batches.
