> Applications
Doramectin is used by veterinary pharmaceutical manufacturers and research groups developing antiparasitic products for internal and external parasite control in livestock. API supply is intended for qualified buyers who will confirm species, indication language, residue limits, withdrawal periods, and finished-dose registration requirements in their own markets.
Livestock endectocide formulation research
A field study reported Doramectin efficacy against gastrointestinal nematodes and lungworms in naturally infected cattle and pigs, with 40 cattle and 100 pigs allocated to treated and control groups (Parasitology Research, 1993, doi:10.1007/BF00932246, n=140). This supports Doramectin API relevance for veterinary endectocide formulation programs involving production animals.
Macrocyclic lactone development programs
Buyers typically evaluate Doramectin assay, related substances, residual solvents, water content, microbial limits, particle properties, and stability behavior before moving from sample quantities to pilot or commercial batches. We supply API only, not finished veterinary injectable, pour-on, or oral products.
