Obidoxime is an antidote for organophosphorous nerve agent poisoning including chlorosarin, cyclosarin (GF), R-33 (VR), R-VX, sarin (GB), tabun (GA), VX, chlorosoman, soman (GD), and organophosphorous pesticides. It acts as an acetylcholinesterase (AChE) reactivator. In combination with atropine obidoxime can be used to treat super toxic organophosphate poisoning by relieving the symptoms of skeletal neuromuscular blocking that occurs during a cholinergic crisis.
