Ivermectin powder is a broad-spectrum antiparasitic agent. In the veterinary sector, it is used to manufacture treatments for livestock and pets against gastrointestinal roundworms, lungworms, and external parasites like mites and lice. In some jurisdictions, it is also used as an active pharmaceutical ingredient (API) for human topical applications (e.g., treating rosacea or head lice). Buyers must ensure the particle size (mesh size) is compatible with their specific formulation process, whether for tableting, oral drench, or injectable solutions.
