What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to certain proteins in parasites, causing their paralysis and death. This mechanism effectively eradicates infections by disrupting the normal functioning of parasitic nerve and muscle cells.
Originally developed for veterinary use, ivermectin has been used in humans for conditions like river blindness and other parasitic infections. Its effects are not targeted at viruses; instead, they are specific to parasites, making it crucial to use ivermectin for the right conditions.
