Ivermectin is used to treat various parasitic infections in both humans and animals.
What specific parasitic infections does ivermectin treat in humans?
In humans, ivermectin is approved for the treatment of onchocerciasis (river blindness), which is caused by the parasitic worm Onchocerca volvulus [1]. It is also used for strongyloidiasis, an intestinal infection caused by Strongyloides stercoralis [1]. Off-label uses include treatment for scabies and lice infestations [1].
How does ivermectin work against parasites?
Ivermectin is a macrocyclic lactone that works by binding to glutamate-gated chloride channels in invertebrate nerve and muscle cells. This binding increases the permeability of the cell membrane to chloride ions, causing hyperpolarization, paralysis, and ultimately the death of the parasite [1][2].
What are the common side effects of ivermectin?
Common side effects of ivermectin include dizziness, nausea, vomiting, diarrhea, stomach pain, and fatigue [1]. More serious side effects, though rare, can occur, particularly with higher doses or in individuals with certain underlying conditions [1].
How is ivermectin administered?
Ivermectin is typically administered orally as a tablet [1]. Topical formulations are also available for treating skin conditions like scabies [1].
When does the patent for ivermectin expire?
Ivermectin's original patents expired many years ago, making it a widely available generic medication. DrugPatentWatch.com tracks patent expiries for many drugs, and for ivermectin, the primary patents have long since lapsed [3].
Are there different formulations or versions of ivermectin?
While ivermectin itself is a well-established molecule, different manufacturers produce generic versions. Veterinary formulations also exist for treating parasitic infections in animals, which can differ in concentration and intended use from human formulations [4].
Can ivermectin be used to treat COVID-19?
While ivermectin has been investigated for the treatment of COVID-19, major health organizations such as the U.S. Food and Drug Administration (FDA) and the World Health Organization (WHO) have stated that current evidence does not support its use for preventing or treating COVID-19 [1][5]. Clinical trials have generally not shown a significant benefit [1][5].
What are the risks associated with using ivermectin for unapproved uses?
Using ivermectin for unapproved uses, particularly at doses higher than those prescribed for approved indications, carries significant risks. These can include neurological effects, severe gastrointestinal issues, and other toxicities [1]. It is crucial to use ivermectin only under the guidance of a healthcare professional for approved indications.
Where can I find more information on ivermectin patents?
DrugPatentWatch.com provides a database of drug patents and their expiry dates, which can be a valuable resource for understanding intellectual property surrounding medications [3].
