Rather, the government "is taking these actions for preparedness purposes only at this time to help ensure an adequate supply of atropine auto-injectors," Smith Dyer said.Thornton SL, Whitacre J, Pallo N, Roberts N, Oller L. Smith Dyer noted that the FDA's authorization of the new atropine injector is not an indication that a chemical nerve agent attack in the United States is imminent. What's more, animal studies have shown that midazolam is a good treatment for nerve gas poisoning, and clinical trials are underway for studies in people, according to Bloomberg. So, an injector would trump an IV, which takes more time to set up, Nelson said. Time is valuable during a nerve gas attack, as these antidotes must be given quickly, within about 10 minutes if possible, he said. The advantage of using midazolam instead of Valium is that midazolam appears to work just as well when delivered with an auto-injector, Nelson said. However, Valium is more effective given intravenously (IV) than in an auto-injector. To stop seizures in people exposed to nerve agents, doctors can currently use diazepam (brand name Valium). "Having atropine conceptually good, but it's not the antidote half that we need. "I don't think is going to make a substantial impact on the treatment of people with nerve agent poisoning," Nelson told Live Science. Ītropine blocks acetylcholine receptors, but it works better on people exposed to insecticides that contain organophosphates, rather than people exposed to nerve agents, Nelson said. This can lead to excess fluid release in the body, such as excess salivation, urination and diarrhea (symptoms typically associated with organophosphate insecticide exposure), and muscle paralysis and death (symptoms usually associated with nerve agent exposure). When this enzyme is out of commission, acetylcholine can continuously stimulate certain receptors on nerve cells, Nelson said. Nerve agents target an enzyme that turns off acetylcholine, a molecule that sends signals to the nerves.
What is atropine?Ītropine, pralidoxime and midazolam are three antidotes that can treat people exposed to nerve agents, which belong to a group of chemicals called organophosphates, Nelson said. citizens living abroad, according to an order he signed on April 11. Department of Health and Human Services, said the authorization of the new injector was needed because "there is a significant potential for a public health emergency," that could affect U.S. This auto-injector "is not currently available for purchase at this time," Smith Dyer said, adding that the new emergency authorization was critical for addressing "preparedness and stockpiling requirements for chemical nerve agent threats." The auto-injector that can dispense atropine along with pralidoxime has experienced a production shortage, according to news reports. "It's really the pralidoxime, and we need midazolam," he told Live Science. Nelson said spending time and money to approve midazolam is crucial, "because for nerve agent, atropine is not really the operative agent" in treating people. A third drug, called midazolam, which is an anticonvulsant, is showing potential in clinical studies, but the drug is not approved by the FDA for nerve gas treatment.
