Ivermectin is a broad-spectrum antiparasitic agent used primarily for the treatment of onchocerciasis (river blindness), strongyloidiasis, and other parasitic infections. It is also approved for the treatment of scabies and certain other ectoparasitic infestations. Ivermectin has been evaluated off-label for a range of other infectious diseases but is primarily used as an antiparasitic agent. It is FDA and EMA approved for parasitic infections in humans.
Pharmacokinetics
Healthy adult volunteers, both sexes, administered a single oral dose of ivermectin.
