Core Tip

Core tip: This paper reviews milestones in antidotal therapies for cyanide (CN) spanning early history, current antidotal systems, and research towards next generation therapies. Presently used CN therapies include: methemoglobin/nitric oxide generators (e.g., sodium nitrite, amyl nitrite, and dimethyl aminophenol), sulfur donors (e.g., sodium thiosulfate and glutathione), and direct binding agents (e.g., hydroxocobalamin and dicobalt edetate). New antidotes, formulations, and delivery systems are presently being developed for rapid administration at the point of intoxication in mass casualty scenarios. These hold promise for a new generation of improved CN countermeasures.
