Ivermectin (22,23-dihydroavermectin B1a + 22,23-dihydroavermectin B1b) is a broad-spectrum antiparasitic avermectin medicine.

Ivermectin is a broad-spectrum antiparasitic agent.

Helminth

It is traditionally used against worms.

It is mainly used in humans in the treatment of onchocerciasis, but is also effective against other worm infestations (such as strongyloidiasis, ascariasis, trichuriasis, filariasis, enterobiasis and some epidermal parasitic skin diseases (EPSDs), including scabies.

Ivermectin, under the brand name Mectizan, is currently being used to help eliminate river blindness (onchocerciasis) in the Americas, and to stop transmission of lymphatic filariasis and onchocerciasis around the world.[2][3][4] Currently, large amounts of ivermectin are donated by Merck to fight river blindness in countries unable to afford the drug.[5] The disease is endemic in 30 African countries, six Latin American countries, and Yemen, according to studies conducted by the World Health Organization.[6] The drug rapidly kills microfilariae, but not the adult worms. A single oral dose of ivermectin, taken annually for the 10-15 year life span of the adult worms, is all that is needed to protect the individual from onchocerciasis.[7]
