WASHINGTON (Reuters) - The U.S. government on Friday urged drug companies to begin marketing pills containing Prussian blue, an artist's pigment used for centuries that can also protect people exposed to a radioactive "dirty bomb."
The Food and Drug Administration called on pharmaceutical companies to apply for licenses to market 500-milligram pills of Prussian blue, or ferric hexacyanoferrate(II), saying it "has been shown to be safe and effective in treating people exposed to radioactive elements such as cesium-137."
Health and Human Services Secretary Tommy Thompson said the action was part of an effort to boost production of drugs that could be used in the event of another terrorist attack, especially one involving radioactive materials.
The FDA said Prussian blue, which binds with radioactive particles and expels them from the body, would be the first therapy available to decrease radiation exposure. The main side effects were constipation and stomach upset.
It said the drug could be used to treat patients with known or suspected internal contamination with radioactive thallium, non-radioactive thallium, or radioactive cesium.
FDA said cesium-137, found in the fallout from the detonation of nuclear weapons and in the waste from nuclear power plants, was of particular concern because it could potentially be use to build a dirty bomb. Exposure to cesium can cause serious illness and possibly cancer.
TREATMENT IN BRAZIL
An agency spokeswoman said Prussian blue is produced in the United States, but not under pharmaceutical standards. She said it has been used experimentally since the 1960s as an orally ingested drug to increase fecal excretion of cesium and thallium without it being absorbed through the intestines.
There are no other FDA-approved treatments for contamination with thallium or radioactive cesium, FDA said.
Prussian blue was used to treat 250 people in Brazil in 1987 after they were contaminated with cesium-137 abandoned after use in a cancer clinic, helping expel the radioactive materials more quickly.
U.S. authorities are holding Jose Padilla, a U.S. citizen who was captured in May and is accused of plotting with al Qaeda to detonate such a device.
A so-called "dirty bomb" involves exploding a conventional bomb wrapped in radioactive material that can kill victims in the immediate area and spread highly toxic material to humans, causing mass death and injury.
Prussian blue was first synthesized in 1704 and has been used as an industrial and artist's pigment since 1724.
Currently only made by our friend Germany.
[There were also recipes in the ‘70’s that used it as a coloring agent in making salt/sugar crystals.]
I remember it as being (something) Blue - "Prussian" sounds right. It used to be used as an antibiotic sort of thing. It came in a small bottle; in liquid form. It’d stain your fingers purple for a week or more.
Our horses would scrape their leg on the fence and we’d have to drain the infected wound, give an antibiotic shot and dress the wound with the purple liquid. I thought it was Prussian Blue. I could be wrong…
I know it’s a dumb question, I'm just trying to figure out if it's the same stuff I saw as a kid... it's interesting to see the various uses of different things.
BTW...Blu-Kote is reported to be one of the few OTC items that will 'kill off' tetnus 'germies'.
That's it. Thanks.
(I live within 5 miles of nuke plant. After a bunch of publicity after 9/11, the county health service gave away the PI pills at nearby schools. When they asked how many live at our house I counted the dogs and two imaginary friends. Just in case some real friends are visiting when the SHTF)
KI has no effect on other radionuclide. The primary radionuclides likely to be present in a release plume any signbificant distance (e.g., five miles) downwind are fission gases, the primary ones being the noble gases xenon and krypton. Those produce a submersion dose, but don't accumulate in the body. So blockers and chelating agents aren't going to be of any effect except increasing your risks because of adverse reaction to the compounds.
