Ivermectin is an antiparasitic drug that belongs to the avermectin class. Its active ingredient is derived from avermectin B1, which is a mixture of two homologues: 22,23-dihydro avermectin B1a and 22,23-dihydro avermectin B1b. The drug is typically formulated as tablets for oral administration or as a lotion or cream for topical use.
What is Ivermectin Used For?
Ivermectin is primarily used to treat parasitic infections in both humans and animals. In humans, it is effective against a range of conditions caused by parasitic worms, including onchocerciasis (river blindness), strongyloidiasis, and scabies [1]. For animals, it is used to prevent and treat heartworm disease and various internal and external parasites in livestock and pets [2].
How Does Ivermectin Work?
The mechanism of action for ivermectin involves disrupting the normal muscle and nerve function of parasites. It binds to glutamate-gated chloride channels in invertebrate nerve and muscle cells, increasing the permeability of the cell membrane to chloride ions. This influx of chloride ions leads to hyperpolarization of the cell, resulting in paralysis and eventual death of the parasite [3].
What Are the Different Formulations of Ivermectin?
Ivermectin is available in various formulations to suit different applications and routes of administration. These include oral tablets, topical lotions, and creams. The specific formulation and dosage depend on the type and severity of the parasitic infection, as well as the patient's age and weight [1].
