Are there any antidotes for nerve agent poisoning?
Antidotes. Atropine and related anticholinergic drugs act as antidotes to nerve agent poisoning because they block acetylcholine receptors, but they are poisonous in their own right. Some synthetic anticholinergics, such as biperiden, may counteract the central symptoms of nerve agent poisoning better than atropine,…
