Famphur is an organophosphate compound primarily used as an insecticide and antiparasitic agent in veterinary medicine. It is effective in controlling external parasites, such as lice, mites, and flies, on livestock, especially cattle. Famphur works by inhibiting acetylcholinesterase, an enzyme essential for nerve function, causing paralysis and death in target parasites. Due to its toxicity, its use is regulated, and proper handling is required to avoid adverse effects on non-target organisms, including humans and the environment.
