> Applications
Moxidectin is a macrocyclic lactone antiparasitic that interacts with glutamate-gated chloride channels in susceptible parasites. API buyers use it in development programs for veterinary endectocide products, including oral, topical, and injectable formulations, while confirming local regulatory requirements for each finished dosage form and species.
Heartworm prevention and veterinary endectocide development
In controlled and field studies of ProHeart 12, an extended-release moxidectin injectable formulation was reported as 100% effective for one-year prevention of Dirofilaria immitis heartworm disease in dogs, including two laboratory studies and a 297-dog multi-site clinical field study (Parasites & Vectors, 2019, doi:10.1186/s13071-019-3659-6). These data support moxidectin relevance for veterinary antiparasitic formulation and research programs.
Formulation and research use
Moxidectin API buyers usually evaluate assay, related substances, nemadectin-related impurities, residual solvents, particle size, and stability data before moving from sample quantities to pilot or commercial batches. The material is intended for qualified pharmaceutical, compounding, or research buyers, not for direct animal administration as bulk powder.
