  • Patent number: 5011853
    Abstract: This invention discloses the use of muscarinic anti-cholinergic agents for reducing or preventing the toxic or lethal effects (such as seizures and brain damage) caused by cholinergic neurotoxins. The parent application disclosed that certain muscarinic anti-cholinergics classified as aryl-cycloalkyl-alkanolamines are effective in reducing or preventing the neurotoxicity of soman, a powerful nerve gas. This invention extends that discovery and identifies other muscarinic anti-cholinergic agents, including scopolamine, benactyzine, and benztropine, as highly effective and useful agents to protect against two major classes of cholinergic neurotoxins (acetylcholine receptor agonists, and cholinesterase inhibitors). Analogs of those compounds may also be effective in protecting against cholinergic neurotoxicity, as can be determined through routine screening tests using rats.
