WebSarin is a nerve agent, which means it interferes with the normal signaling between nerve cells. It acts in much the same way as organophosphate insecticides, block nerve endings from allowing muscles to stop contracting. Death may occur when the muscles controlling breathing become ineffective, causing asphyxiation. WebSarin, a very potent organophosphate nerve agent, inhibits acetylcholinesterase (AchE) activity within the central, peripheral, and autonomic nervous systems. Acute and long-term sarin effects upon humans were well documented in these two events. Sarin gas inhalation caused instantaneous death by respiratory arrest in 4 victims in Matsumoto.
