Trimedoxime is the only one of the major bispyridinium oxime with a propylene linked between the two pyridinium rings. Trimedoxime is an oxime cholinesterase (AChE) reactivator. It was shown that trimedoxime is a more potent reactivator of the DFP-inhibited AChE than pralidoxime and a better reactivator than obidoxime in the case of the tabun-inhibited enzyme. It can be used parenterally as an antidote adjunct to atropine in treating human or animal (organophosphate group) anticholinesterase pesticide toxicity. Trimedoxime was the first oxime that was efficient in the treatment of animals intoxicated with tabun. It could also protect animals poisoned with sarin or VX, but not the ones intoxicated with soman.
