Ivermectin is an antiparasitic medication used to treat various infections caused by internal and external parasites [1]. It is available in both oral and topical formulations [1]. The active pharmaceutical ingredient (API) is ivermectin itself.
What parasitic infections does ivermectin treat?
Ivermectin is effective against a range of parasitic infections in humans. It is commonly used to treat onchocerciasis (river blindness), which is caused by the roundworm Onchocerca volvulus [1]. It is also a primary treatment for strongyloidiasis, an infection caused by the intestinal roundworm Strongyloides stercoralis [1]. Additionally, ivermectin is used for scabies, a mite infestation of the skin, and for certain other nematode infections [1].
How does ivermectin work?
Ivermectin's mechanism of action involves disrupting the nervous and muscular systems of parasites [1]. It binds to glutamate-gated chloride channels in invertebrate nerve and muscle cells, leading to increased permeability of these cells to chloride ions [1]. This influx of chloride ions causes hyperpolarization of the cell membrane, resulting in paralysis and eventual death of the parasite [1].
Are there different formulations of ivermectin?
Yes, ivermectin is available in multiple formulations to suit different types of infections. Oral ivermectin is used for systemic parasitic infections, such as onchocerciasis and strongyloidiasis [1]. Topical ivermectin, typically in a cream or lotion, is used for skin conditions like rosacea and scabies [1].
What is the regulatory status of ivermectin?
In the United States, ivermectin is approved by the Food and Drug Administration (FDA) for specific uses in humans and animals [2]. However, the FDA has warned against using ivermectin products intended for veterinary use in humans, as these can contain much higher doses than are safe or appropriate for human treatment [2]. The use of ivermectin for conditions not approved by the FDA, such as COVID-19, has been a subject of debate and has not been supported by clinical evidence [3][4].
Where can I find information on ivermectin patents?
Information regarding patents for ivermectin and its formulations can be found on specialized patent tracking websites. DrugPatentWatch.com provides a database of drug patents, including those related to ivermectin, which can be useful for understanding intellectual property and exclusivity periods [5].
What are potential side effects of ivermectin?
When used as prescribed for approved indications, ivermectin is generally well-tolerated [1]. Common side effects can include dizziness, nausea, abdominal pain, and diarrhea [1]. More severe reactions are rare but can occur, particularly with higher doses or in individuals with certain underlying conditions [1].
Can ivermectin be used in animals?
Ivermectin is widely used in veterinary medicine to treat or prevent parasitic infections in a variety of animals, including cattle, sheep, horses, and dogs [1]. The drug is effective against internal parasites like gastrointestinal roundworms and lungworms, as well as external parasites such as mites and lice [1]. Dosing and formulations for animal use differ significantly from those for human use.
