EMD Pharmaceuticals, which is based in Durham, and drug partner Dey, L.P. have received Food and Drug Administration approval to sell a kit for the treatment of known or suspected cyanide poisoning.

MED sought approval of the kit, known as Cyanokit, in June. It was approved for use in France a decade ago.

Dey, which is based in California, plans to begin marketing the kit in the U.S. early next year.

According to the companies, the cyanide antidote is the first approved in the U.S. in several decades.

The companies plan to market the kit for use in the event of industrial accidents or a terrorist attack involving deadly cyanide.

The kits can be used to treat cyanide poisoning from smoke inhalation and other causes.
