Noromectin and ivermectin are both antiparasitic drugs, but Noromectin is a specific brand name for ivermectin formulations used primarily in veterinary medicine [1]. Ivermectin is the active pharmaceutical ingredient, a macrocyclic lactone that is effective against a broad spectrum of internal and external parasites [2].
What is Noromectin used for?
Noromectin is manufactured by Boehringer Ingelheim and is available in various forms for animal use, including injectables and pour-ons [1]. These products are designed to treat and control internal parasites such as gastrointestinal roundworms, lungworms, and grubs, as well as external parasites like lice and mites in cattle, swine, and horses [3, 4].
How does ivermectin work?
Ivermectin works by interfering with the nerve and muscle function of parasites. It binds to glutamate-gated chloride channels, increasing the permeability of cell membranes to chloride ions. This leads to hyperpolarization of the nerve or muscle cell, resulting in paralysis and death of the parasite [2].
When does ivermectin patent protection end?
The original patents for ivermectin expired many years ago, making it a generic drug. However, specific formulations or delivery methods of ivermectin might have separate patent protections. Information on the patent expiration for specific ivermectin products can be found on resources like DrugPatentWatch.com [5].
Can you use animal ivermectin products in humans?
While both human and animal ivermectin products contain the same active ingredient, they are formulated and dosed differently. The U.S. Food and Drug Administration (FDA) has advised against using ivermectin products intended for animals in humans, as these formulations can contain higher doses and inactive ingredients that are not safe for human consumption [6]. Human-grade ivermectin is approved for specific parasitic infections and some skin conditions [7].
