The government is quietly shipping stocks of antidotes against chemical weapons (search) to states under a long-awaited program to boost response to a potential terrorist attack.

New York and Boston, sites of the upcoming political conventions, were among the first areas to receive the "chem-packs" (search).

"It's a quick way for hospitals to know they'll have the antidotes they need," Donna Knutson, CDC's deputy director of terrorism preparedness, said Tuesday in an interview with The Associated Press.

The program was begun in part because there has been "an uneven level of protection across the country," added Steve Adams, deputy director of the Strategic National Stockpile Program (search).

Much of the nation's efforts to prepare for terrorism have focused on biological attacks. For example, the National Pharmaceutical Stockpile contains tons of drugs, vaccines and other medical supplies in storage around the country, so that any U.S. city could receive an emergency shipment within 12 hours.

That's probably plenty of time to react to an incubating infection like anthrax, but the ability to survive a chemical attack depends on immediate decontamination and rapid administration of appropriate antidotes.

Yet the antidotes are expensive and have fairly short shelf lives, making them hard for many states to keep stocked.

Enter the chem-packs, which CDC began shipping four months ago.

The gurney-sized packs come with an assortment of antidotes to the many chemicals available to a terrorist; atropine to fight nerve agents, for instance, or amyl nitrite for cyanide. Some are in autoinjectors for use at the site of an attack, others packaged for emergency-room use.

For security reasons, CDC officials wouldn't say which states had received chem-packs so far, naming only New York and Boston.

New York received its first packs under a pilot program a year ago, said Jared Bernstein of the city's Office of Emergency Management. Now, looking toward next month's Republican convention, the city has received updated supplies.

The initial pilot program stalled when it was shuffled among federal agencies, said former Health and Human Services public health preparedness chief Jerry Hauer. "It's about time" the program was restarted, he said.

The number distributed depends upon each state's population, and state health departments decide which hospitals will store chem-packs. Hospitals will be able to decide when it's time to break one out and use the contents.

"When minutes matter, if they need it to save lives, they have the authority to break the seals and go do the right thing," Adams said.

The CDC spent $56 million last year in creating the chem-packs and has budgeted about $34 million this year as the distribution begins, officials said.

"It's the next logical step," said Dr. Georges Benjamin of the American Public Health Association, which long urged the federal government to increase chemical-attack preparedness.

The chem-packs will ensure "you have a ready cache of supplies if you have a large number of chemical victims," he said. Plus, "the right doses will be there, and hopefully you don't have to worry about people making up medications and overdosing or underdosing patients."

While CDC would not provide details, hospitals expect each chem-pack to be able to treat 1,000 patients, said James Bentley, the American Hospital Association's disaster-readiness chief.

Nor are the packs reserved solely for terrorist attacks. The same antidotes would be useful for a major factory accident or train wreck that spilled hazardous chemicals, Bentley said.

The specially sealed packs come with environmental sensors to ensure the materials are stored properly. That is crucial: Until the seal is broken, the chem-pack contents qualify for a federal program that extends their expiration dates for several years, potentially saving thousands of taxpayer dollars, Adams explained.

"That's why it makes sense for us to be in the business," instead of just funding states to buy their own drugs, he said. "That's the benefit the locals see — it's not a one-time deal."
