EA-3148

The chemical structure of EA-3148 falls within the scope of compounds designated "Toxic chemicals" under Schedule 1 of the Chemical Weapons Convention and so it is illegal throughout the world under international law and may only be used for certain types of scientific and medical research.

Effects

A healthy American male soldier was given EA-3148, 1.15 μg/kg i.v.. Erythrocyte AChE values dropped precipitously to 22% of normal within 15 min of dosing and to 0% at 48 h; the value recovered to 88% of normal at 72 days post-exposure. Signs of toxicity were evident within 5-8 min of treatment in two comparably dosed subjects who felt dizzy, weak, tired, sweaty, and had hands and feet that were moist. Within 2 h post-exposure, these subjects reportedly were resting, eating, and feeling fine.

A U.S. Army report summarizing experience with EA-3148 noted anorexia, fatigue, poor sleep, unusual dreams, dizziness, euphoria, blurred vision, increased salivation, restlessness; decrements in a test of numerical facility in four individuals and exaggeration of a schizoid personality in one male soldier.
