Dicobalt edetate was developed as a cyanide antidote based on the known ability of cobalt to form stable complexes with cyanide. One current cobalt-based antidote available in Europe is dicobalt-EDTA, sold as Kelocyanor. This agent chelates cyanide as the cobalticyanide. This drug provides an antidote effect more quickly than formation of methemoglobin. It can be very toxic and cause seizures, upper airway oedema, chest pain, hypotension, vomiting, rashes and dyspnoea especially in those who have not be exposed to cyanide.

Originator

Curator's Comment: The first use of cobalt compounds as cyanide antagonists was advocated by Antal J. in 1894. http://www.firesmoke.org/wp-content/uploads/2010/10/Cyanide_As_A_Weapon.pdf

Sample Use Guides

In Vivo Use Guide
Curator's Comment: Also was used orally in rats: Cobalt disodium ethylenediamine tetra-acetate in a dosage of 4, 8, 10, 20, 40 mg/Kg of elemental cobalt had no effect on the weight gain of weanling rats.
Rabbits: Rabbits receiving 50 mg/Kg of elemental cobalt intravenously, given as cobalt disodium ethylenediamine tetra-acetate (Cobalt Disodium Edetate), showed no detectable toxic symptoms. Approximately 100 mg/Kg elemental cobalt, administered as rapidly as possible, still produced no toxic symptoms except for a questionable increase in respiratory rate.
Route of Administration: Intravenous
