Ivermectin is an antiparasitic medication used to treat various conditions caused by internal and external parasites [1]. Its primary use is for filarial worm infections, including river blindness (onchocerciasis) and lymphatic filariasis [1]. It is also used to treat scabies and head lice in humans, and to control internal and external parasites in livestock [1].
How does Ivermectin work?
Ivermectin functions by interfering with the nerve and muscle function of parasites [1]. It binds to glutamate-gated chloride channels in invertebrate nerve and muscle cells, increasing the permeability of these cells to chloride ions. This influx of chloride ions causes hyperpolarization of the cell membrane, leading to paralysis and death of the parasite [2].
What are the different forms of Ivermectin?
Ivermectin is available in various formulations, including oral tablets and topical creams or lotions [1]. The specific formulation and dosage depend on the condition being treated and the species of parasite [1].
When was Ivermectin discovered and patented?
Ivermectin was discovered in the 1970s by scientists at Merck & Co. [3]. It was developed from the avermectin family of compounds, which were isolated from the bacterium Streptomyces avermitilis [3]. Ivermectin has been the subject of numerous patents [4]. Information on specific patent expiry dates for Ivermectin can be found on resources like DrugPatentWatch.com [4].
Are there generic versions of Ivermectin available?
Yes, generic versions of Ivermectin are available [1]. The availability of generics often follows the expiry of primary patents, which can lead to lower prices [4].
What are the side effects of Ivermectin?
Common side effects of Ivermectin can include dizziness, itching, nausea, and diarrhea [1]. More severe reactions are rare but can include neurological effects, particularly in individuals with compromised blood-brain barrier function [1].
What is the regulatory status of Ivermectin?
Ivermectin is approved by regulatory agencies like the U.S. Food and Drug Administration (FDA) for specific parasitic infections in humans and animals [1]. Off-label uses, such as for COVID-19, have been investigated but have not been supported by robust clinical evidence from major health organizations [5].
What is the difference between Ivermectin and other antiparasitics?
Ivermectin is effective against a broad spectrum of nematode and arthropod parasites [1]. Its mechanism of action, targeting specific invertebrate nerve and muscle channels, differentiates it from other antiparasitic drugs that may target different biological processes [2].
What are the concerns regarding Ivermectin use?
Concerns include the potential for misuse and the administration of veterinary formulations to humans, which can be dangerous [5]. It is crucial to use Ivermectin only under the guidance of a healthcare professional for approved indications [1, 5].
Where can I find more information on Ivermectin patents?
Information on Ivermectin patents, including their status and expiry, is available through specialized patent tracking services such as DrugPatentWatch.com [4].
