Learn about ivermectin, a medication used to treat various parasitic infections in humans and animals. Find out how it works, its side effects, and its potential off-label uses for treating COVID-19.
What is the medicine ivermectin
Ivermectin is a medication that has gained significant attention in recent times due to its potential use in treating various conditions. Originally developed as an antiparasitic drug, Ivermectin has shown promising results in treating a range of infections caused by parasites, such as head lice and river blindness. However, its off-label use for other conditions, including COVID-19, has sparked controversy and debate among medical professionals and researchers.
Originally discovered in the 1970s, Ivermectin belongs to a class of drugs called avermectins, which are derived from the soil bacterium Streptomyces avermitilis. It works by interfering with the nervous system of parasites, leading to their paralysis and eventual death. This mechanism of action has made Ivermectin an effective treatment for various parasitic infections.
While Ivermectin has been widely used and proven to be safe for its approved indications, its use for off-label purposes, especially in the context of COVID-19, remains highly controversial. Some studies and anecdotal evidence suggest that Ivermectin may have antiviral properties and could potentially be effective in reducing the severity of COVID-19 symptoms. However, the scientific community has called for further research and clinical trials to determine its true efficacy and safety in treating the virus.
It is important to note that Ivermectin should only be used under the supervision of a healthcare professional, and self-medication or misuse of the drug can lead to harmful side effects. As with any medication, it is crucial to follow the prescribed dosage and treatment duration to ensure optimal results and minimize the risk of adverse reactions.
In conclusion, Ivermectin is a medication with proven efficacy in treating parasitic infections. While its potential use in treating other conditions, such as COVID-19, is being investigated, further research is needed to establish its safety and efficacy in these off-label applications. It is essential to consult with a healthcare professional before considering the use of Ivermectin for any purpose other than its approved indications.
History and Development of Ivermectin: From Discovery to Medical Use
Ivermectin, a medication widely used to treat various parasitic infections, has a fascinating history that spans several decades. The discovery of this powerful drug can be attributed to the collaborative efforts of Japanese scientist Satoshi Ōmura and Irish pharmacologist William C. Campbell, who were jointly awarded the Nobel Prize in Physiology or Medicine in 2015 for their groundbreaking work.
In the late 1970s, Ōmura, working at the Kitasato Institute in Japan, isolated a strain of bacteria called Streptomyces avermitilis from soil samples. This strain was found to produce a compound that displayed potent activity against parasites, particularly those causing diseases such as river blindness and lymphatic filariasis.
Recognizing the potential of this compound, Ōmura collaborated with Campbell, then working at Merck Sharp & Dohme Research Laboratories in the United States, to further investigate its properties. Campbell’s team successfully identified and purified the active compound, which they named «avermectin.»
However, avermectin was found to have limited solubility and thus posed challenges for formulation into a suitable medicine. To overcome this, Merck scientists chemically modified avermectin to produce a more soluble and therapeutically effective derivative called «ivermectin.»
Ivermectin was first approved for veterinary use in the early 1980s and quickly gained recognition for its remarkable efficacy against a wide range of parasites in animals. Its success in veterinary medicine paved the way for its development as a human medicine, with clinical trials conducted to assess its safety and effectiveness.
In 1987, the U.S. Food and Drug Administration (FDA) approved ivermectin for the treatment of onchocerciasis, commonly known as river blindness, making it the first drug ever to be approved for the treatment of a neglected tropical disease. Since then, ivermectin has been approved for additional parasitic infections, such as strongyloidiasis and scabies.
Today, ivermectin is included in the World Health Organization’s List of Essential Medicines, which highlights the most effective and safe medications needed in a healthcare system. It continues to be a crucial tool in the fight against parasitic diseases, improving the lives of millions of people worldwide.

Mechanism of Action: How Ivermectin Works in the Body
Ivermectin is a medication that has been used for decades to treat various parasitic infections. It belongs to a class of drugs called avermectins, which are derived from the soil bacterium Streptomyces avermitilis. Ivermectin works by targeting and disrupting the nervous system of parasites, ultimately leading to their paralysis and death.
The mechanism of action of ivermectin involves its binding to certain receptors in the parasites’ nerve and muscle cells. These receptors are called glutamate-gated chloride channels, which are crucial for normal functioning of the parasites’ nervous system.
Once bound to the receptors, ivermectin enhances the release of a neurotransmitter called gamma-aminobutyric acid (GABA) in the parasites’ nervous system. GABA is an inhibitory neurotransmitter, meaning it reduces the activity of nerve cells. By increasing the release of GABA, ivermectin effectively inhibits the transmission of nerve signals in the parasites, leading to paralysis and death.
Furthermore, ivermectin also disrupts the parasites’ ability to feed and reproduce. It affects their ability to take up nutrients from the host’s body and impairs their reproductive organs, preventing them from laying eggs or producing viable offspring.
It is important to note that while ivermectin is highly effective against a wide range of parasites, it does not have the same effect on human cells. This is because the glutamate-gated chloride channels that ivermectin targets are much more specific to parasites and are not found in the same form in human cells. Therefore, the drug can selectively target and eliminate parasites without causing harm to the human body.
Overall, the mechanism of action of ivermectin involves its binding to specific receptors in parasites’ nerve and muscle cells, enhancing the release of GABA, and disrupting their ability to feed and reproduce. This unique mode of action has made ivermectin an essential medication in the treatment of parasitic infections.
Medical Uses of Ivermectin: Treating Parasitic Infections
Ivermectin is a medication that is primarily used to treat parasitic infections in humans. It belongs to a class of drugs known as antiparasitic agents and works by paralyzing and killing parasites.
One of the most common uses of ivermectin is for the treatment of onchocerciasis, also known as river blindness. This disease is caused by a parasite called Onchocerca volvulus, which is transmitted through the bites of blackflies. Ivermectin effectively kills the larvae of the parasite, preventing the progression of the disease and reducing the risk of blindness.
Ivermectin is also used to treat other parasitic infections, such as strongyloidiasis, a condition caused by the roundworm Strongyloides stercoralis. This parasitic infection can affect various organs in the body, including the lungs and intestines. Ivermectin works by killing the adult worms and preventing the release of their eggs, thus helping to alleviate the symptoms and reduce the risk of complications.
In addition, ivermectin is used in the treatment of scabies, a highly contagious skin condition caused by the Sarcoptes scabiei mite. This parasitic mite burrows into the skin, causing intense itching and a rash. Ivermectin can effectively kill the mites and their eggs, providing relief from the symptoms and preventing the spread of the infection.
Furthermore, ivermectin has shown promise in the treatment of other parasitic infections, such as head lice and certain types of filariasis. It is often used in combination with other medications to ensure the effective eradication of the parasites.
It is important to note that while ivermectin is highly effective in treating parasitic infections, it is not effective against viral or bacterial infections. It should only be used under the supervision of a healthcare professional, who can determine the appropriate dosage and duration of treatment based on the specific condition and individual factors.
