22,23-dihydro-avermectin B1a is a major form of Ivermectin mixture (more than 90%). It is a broad-spectrum anthelmintic (worms), microfilaricide (heartworms), and miticide (mites) drug, used for horses, cattle, pigs, household pets. Ivermectin used in humans, especially for river blindness. Ivermectin binds selectively and with high affinity to glutamate-gated chloride ion channels in invertebrate muscle and nerve cells of the microfilaria.
