Discover the origins of ivermectin and its initial development for humans. Explore its uses and benefits in treating various parasitic infections and its role in veterinary medicine.
Ivermectin, a widely used antiparasitic drug, has gained significant attention in recent times due to its potential role in treating COVID-19. However, many people wonder: Was ivermectin developed for humans in the first place?
The answer to this question lies in the origins of ivermectin. Originally, ivermectin was not developed specifically for humans, but rather for veterinary use. It was discovered in the late 1970s by Japanese scientist Satoshi Ōmura and his team at the Kitasato Institute, who were searching for new drugs to combat parasitic infections in animals.
Ōmura’s team was conducting research on soil samples from various locations around the world, looking for microorganisms that could produce substances with therapeutic properties. During their investigation, they isolated a strain of bacteria called Streptomyces avermitilis from a soil sample collected in Japan. This strain was found to produce a compound with potent antiparasitic activity, which was later named ivermectin.
Although initially developed for veterinary use, the potential of ivermectin as a treatment for human parasitic infections was soon recognized. In collaboration with the pharmaceutical company Merck & Co., Ōmura’s discovery led to the development of a human formulation of ivermectin, which was approved by the U.S. Food and Drug Administration (FDA) in 1987 for the treatment of certain parasitic diseases in humans.
The story of ivermectin exemplifies how scientific discoveries made in one field can have unexpected applications in another. While it may not have been originally developed for humans, ivermectin has proven to be a valuable tool in the fight against various parasitic infections, both in animals and humans.
Ivermectin is a medication that has been used for decades to treat various parasitic infections in humans and animals. However, it was not originally developed for humans.
The story of ivermectin begins in the 1970s when a Japanese scientist named Satoshi Ōmura discovered a new strain of bacteria in soil samples from a golf course. This strain, called Streptomyces avermitilis, produced a compound that showed promise in killing parasites.
Ōmura’s discovery caught the attention of another scientist, William C. Campbell, who was working at Merck Research Laboratories in the United States. Campbell and his team isolated and purified the compound from Streptomyces avermitilis, which they named avermectin.
Avermectin was found to be highly effective in treating parasitic infections in animals, and it was later refined into a more potent and safer drug called ivermectin. In 1981, Merck received approval from the U.S. Food and Drug Administration (FDA) to use ivermectin in animals.
However, it wasn’t until 1987 that ivermectin was approved for human use. The drug was shown to be highly effective in treating parasitic diseases such as river blindness and elephantiasis, which affect millions of people in developing countries.
Since then, ivermectin has become an essential medication in the fight against these neglected tropical diseases. It has also been used off-label to treat other parasitic infections and has gained attention recently as a potential treatment for COVID-19, although more research is needed to determine its efficacy in this context.
In conclusion, while ivermectin was not originally developed for humans, it has proven to be a valuable tool in the treatment of parasitic infections in both humans and animals.
Ivermectin, a medication used to treat parasitic infections, was first developed in the late 1970s. It was discovered by Japanese scientist Satoshi Ōmura and his team at the Kitasato Institute in Tokyo. Ōmura and his team were searching for new antibiotics and anti-parasitic drugs from soil samples collected around the world.
In their search, they collected soil samples from various locations, including Japan, Indonesia, and Venezuela. These samples were then screened for potential bioactive compounds. One of the samples collected from a golf course in Japan contained a strain of bacteria called Streptomyces avermitilis, which produced a compound with potent anti-parasitic activity.
In 1978, Satoshi Ōmura sent the soil sample containing Streptomyces avermitilis to William Campbell, a scientist at the Merck Institute for Therapeutic Research in the United States. Campbell was an expert in parasitology and had previously discovered an anti-parasitic compound called avermectin.
Campbell and his team isolated the active compound from the Streptomyces avermitilis culture and named it ivermectin. They found that ivermectin was highly effective against a wide range of parasites, including roundworms, hookworms, and certain mites.
The discovery of ivermectin revolutionized the treatment of parasitic infections, particularly in developing countries where these infections are prevalent. Ivermectin proved to be safe, effective, and affordable, making it an invaluable tool in public health efforts to control and eliminate parasitic diseases.
In recognition of their groundbreaking work, Satoshi Ōmura and William Campbell were awarded the Nobel Prize in Physiology or Medicine in 2015. Their discovery of ivermectin has saved countless lives and continues to have a significant impact on global health.

Ivermectin was initially developed as a veterinary drug and has been widely used to treat parasites in animals. It was first discovered in the 1970s by Japanese scientist Satoshi Ōmura, who was working at the Kitasato Institute in Tokyo. Ōmura and his team were searching for new compounds that could effectively combat parasites in livestock.
After several years of research, Ōmura isolated a strain of bacteria called Streptomyces avermitilis from a soil sample collected in Japan. This strain produced a compound that showed potent activity against parasites, particularly nematodes and arthropods.
The compound was named avermectin and further research led to the development of a more refined version, which was called ivermectin. Ivermectin was found to be highly effective in killing a wide range of parasites in animals, including worms, lice, and mites.
Due to its success in veterinary medicine, ivermectin quickly gained popularity among farmers and veterinarians. It was used to treat various parasitic infections in livestock, such as cattle, sheep, pigs, and horses. The drug was also effective in controlling parasites in pets, including dogs and cats.
Notably, ivermectin was instrumental in controlling the devastating cattle disease known as river blindness in Africa. This disease, caused by the parasitic worm Onchocerca volvulus, can lead to blindness if left untreated. The discovery of ivermectin’s efficacy against this parasite revolutionized the treatment and prevention of river blindness, greatly reducing its prevalence in affected regions.
As a result of its success in animals, researchers began exploring the potential use of ivermectin in humans. Clinical trials were conducted, and it was found that ivermectin was also effective against certain human parasites, such as head lice and scabies.
Today, ivermectin is approved for use in both animals and humans, although the dosage and formulations vary. It remains an essential tool in veterinary medicine, helping to control and prevent parasitic infections in a wide range of animals.
Ivermectin, a medication that has gained significant attention in recent years for its potential use in treating various human illnesses, was originally developed for veterinary purposes. It was first introduced in the 1980s as a treatment for parasitic infections in animals.
