Ivermectin is an antiparasitic medication used to treat various conditions in humans, including certain worm infestations like onchocerciasis (river blindness) and strongyloidiasis [1]. It is also used to treat scabies and head lice [1]. The drug works by paralyzing and killing parasites [2].
What conditions does ivermectin treat in humans?
Ivermectin is approved by the U.S. Food and Drug Administration (FDA) for the treatment of specific parasitic infections [1]. These include onchocerciasis, caused by the filarial worm Onchocerca volvulus, and strongyloidiasis, a parasitic infection caused by Strongyloides stercoralis [1]. It is also used topically to treat ectoparasites like scabies and lice [1].
How does ivermectin work to kill parasites?
Ivermectin is a macrocyclic lactone that interferes with the function of glutamate-gated chloride channels in invertebrate nerve and muscle cells [2]. This disruption leads to increased permeability of the cell membrane to chloride ions, causing hyperpolarization and paralysis, ultimately resulting in the death of the parasite [2].
Are there different forms of ivermectin for human use?
Ivermectin is available in oral tablet form for systemic treatment of internal parasitic infections and in topical formulations (creams and lotions) for treating skin conditions like rosacea, scabies, and lice [3][4].
What is the typical dosage for ivermectin tablets?
Dosage for ivermectin tablets is typically based on body weight and the specific condition being treated [1]. For example, the dose for onchocerciasis is usually a single oral dose [1].
What are the side effects of ivermectin?
Common side effects of oral ivermectin can include dizziness, headache, nausea, vomiting, diarrhea, stomach pain, and skin rash [1]. More severe reactions are rare but can occur, especially in individuals with high levels of microfilariae in their blood [1].
Has ivermectin been investigated for other uses?
Ivermectin has been studied for potential antiviral properties, including against SARS-CoV-2, the virus that causes COVID-19 [5]. However, regulatory agencies like the FDA have stated that there is currently insufficient scientific evidence to support the use of ivermectin for treating or preventing COVID-19 in humans [1][5]. They emphasize that ivermectin has not been approved for this use and that taking large doses can be dangerous [1].
Where can I find more information on ivermectin drug patents?
Information regarding drug patents for ivermectin and other medications can be found on DrugPatentWatch.com [6]. This resource tracks patent expiry dates and provides data relevant to drug exclusivity and market competition [6].
