KATY, Texas, March 25, 2011 /PRNewswire-USNewswire/ -- Heyltex Corporation is the exclusive U.S. distributor of Radiogardase® (Prussian Blue insoluble capsules), the only FDA-approved drug to treat people who have been internally contaminated with radioactive cesium (Cs-137), which is manufactured by Heyl chem. pharm. Fabrik Berlin GmbH in Germany.
Radiogardase® traps radioactive cesium and thallium in the intestines and keeps them from being re-absorbed by the body. Once Cs-137 has entered the body, it goes through a long rotation of re-absorption within the circulatory system. The ingested Cs-137 is reabsorbed almost completely from the gastrointestinal tract, and, via the bloodstream, is transported to the liver where it enters the gall bladder and is finally returned to the intestine. From the intestine, around 90% is again reabsorbed into the bloodstream and the enterohepatic circulation starts anew. Radiogardase® interrupts this enterohepatic absorption of Cs-137 by knocking this cyclic path out of the gastrointestinal tract and sending it out through the feces.
Heyl chem. pharm. Fabrik GmbH is stepping up production of Radiogardase® to help relieve domestic and global demand.
During nuclear incidents, such as the ongoing emergency at the Fukushima Daiichi Nuclear Power Facility, radioactive material can escape from fuel rods because of heating and consequent cracks in the metal rods. A break in the containment structure, because of explosions or damage from other causes, can permit the radioactive material such as Cs-137 to escape to the environment. The released radioactive material can be inhaled, swallowed with contaminated food or water, or enter the body through open wounds.
Drugs that help to remove this radioactive material from the body are called decorporation drugs. Perhaps best known to the general public is potassium iodide (chemically abbreviated KI). This drug helps keep radioactive iodine f
