Ivermectin is an antiparasitic drug that is a mixture of two derivatives of the macrocyclic lactone avermectin [1]. These derivatives are 22,23-dihydroavermectin B1a and 22,23-dihydroavermectin B1b [1]. The ratio of B1a to B1b in the mixture is typically at least 90% B1a [1]. Avermectins are produced by the soil microorganism Streptomyces avermitilis [1].
How is Ivermectin Manufactured?
Ivermectin is synthesized from avermectin, which is a fermentation product of Streptomyces avermitilis [2]. The manufacturing process involves isolating avermectin and then chemically modifying it to produce the final ivermectin product [2].
What are the Uses of Ivermectin?
Ivermectin is used to treat various parasitic infections in humans and animals [3]. In humans, it is effective against onchocerciasis (river blindness), strongyloidiasis, and other helminth infections [3]. It is also used to treat scabies and lice [3]. In veterinary medicine, it is used to prevent heartworm disease in dogs and to treat a range of internal and external parasites in livestock and other animals [3].
What is the Difference Between Ivermectin and Avermectin?
Ivermectin is a semi-synthetic derivative of avermectin [1][2]. While avermectin is the natural product produced by Streptomyces avermitilis, ivermectin is created by hydrogenating avermectin [1][2]. This modification results in a more potent and broader-spectrum antiparasitic agent [1][2].
What are the Potential Side Effects of Ivermectin?
Common side effects of ivermectin can include dizziness, nausea, vomiting, diarrhea, stomach pain, and rash [4]. More serious side effects, though rare, can occur, particularly with high doses or in individuals with certain medical conditions [4].
Are there any Drugs Similar to Ivermectin?
Other macrocyclic lactone drugs, such as moxidectin, share similar antiparasitic properties and are used to treat some of the same conditions as ivermectin [3][5].
What is the Patent Status of Ivermectin?
Ivermectin was developed by Merck & Co. and has been available since the 1980s [6]. As a mature drug, its original patents have long since expired, allowing for the production of generic versions [6].
Where Can I Find More Information on Ivermectin Patents?
