What It Is and How It Works
Ivermectin is a derivative of the compound avermectin, which is produced by the bacteria Streptomyces avermitilis. It works by binding to glutamate-gated chloride ion channels in parasites, causing increased permeability to chloride ions. This results in paralysis and death of the parasite. Its broad-spectrum efficacy makes it useful against a variety of internal and external parasites.
