STOCKHOLM, SWEDEN--(Marketwire - April 01, 2010) -

Under the agreement the distribution territories will include Ireland, UK and The Netherlands in addition to the existing territories the Nordic and the Baltic countries.

"We are very pleased with the expanded and continued partnership with Merck Serono and the opportunity to make the Cyanokit® antidote available in additional countries.

About Cyanokit®

Cyanokit® is a pharmaceutical antidote indicated for the treatment of known or suspected cyanide poisoning. Cyanide poisoning may result from exposure to smoke from closed space fires, inhalation, ingestion, or dermal exposure.

Administered intravenously, Cyanokit® may be used on the scene of an emergency situation or at the hospital, where quick response is critical. Cyanokit® is kept in ambulances and emergency rooms at hospitals, and may be stock piled by governments to be used in case of industrial accidents or a terrorist attack involving cyanide.

The active ingredient in Cyanokit®, hydroxocobalamin, is a form of vitamin B12. Hydroxocobalamin works by binding directly to the cyanide ions, creating cyanocobalamin, a variant of vitamin B12, which is excreted in the urine. Advantages of this approach are that methemoglobin is not produced and the oxygen-carrying capacity of the victim's blood is not lowered.
