New Nerve Gas Antidotes

SoyChemist writes "Scientists from Korea and the Czech Republic have discovered new drugs that can counteract the chemical overload caused by nerve gas. All of the experimental medications belong to a family of chemicals called oximes. Those molecules reactivate the enzyme that is damaged by the chemical weapons. Last year, the FDA approved the first combined atropine and oxime auto-injector for use by emergency personnel. Israel has been providing them to their citizens since the first Gulf War."

Combined, yes. But not new.

I don't know the history, but in 1987(and certainly earlier) the US military had this for the 'troops'. It was in 2 injectors, not one.

atropine and 2 pam chloride (a oxime)

Like you said - Pralidoxime and Atropine injectors are extremely old-school for the US military. Although I'm happy that there are new drugs for treating nerve gas poisoning, TFA makes it sound like the "new" drugs are still completely untested - only on petri dish models, if I read it correctly. So, while there is promise, there are no human or animal efficiency results yet, no toxicity tests - all kinds of things are needed to prove that these new molecules are appropriate to replace the old ones.

That's the thing about new drugs - they look wonderful and promising for a while in the lab, then you stick them in a monkey and his testicles melt or his hair falls out. Oops - back to the drawing board.

Anyway, I'm skeptical but hopeful. I've had biochem weapons training in the Army, and nerve gases are effing nasty. More power to providing more survivability...

better explanation

[wizardforce]

Pralidoxime has been used with Atropine for a long time it seems, Atropine lessening the effects of acetylcholine its self and Pralidoxime is sacrificed to reactivate acetylcholine esterase [which helps remove acetylcholine after it is done with its job]

Excuse to piss in public

I'm being serious here... In the case that I ever end up in a public space where it becomes obvious that a nerve gas has been released, (and there is no clear way of getting out ie. subway system, sports venue...) I would take off one of my socks and piss on it.

???????

This was commonly done in WWI during nerve gas attacks. With lack of gas masks, the best way to protect yourself was to breathe through a cloth soaked in ammonia. Piss being the easiest source of it.

The modern gases may be way more advanced than what was used in early 20th century, so my approach may come across as dumb, but if they find my dead body sucking on a piss stained sock, I won't care much. I'll be dead.

If you really worried about it, you could just carry around a water filter. They make small ones for sports bottles, although, I don't know how easy they are to breathe through. Either way, they seem to have the same stuff in them as modern gas masks. It may work in a pinch and no one runs over your ass while you are standing there DIH, too panicked to piss on a sock.

Piss won't help with any nerve agent. That tactic was partly effective against chlorine gas, which is soluble in water, so any water soaked rag will partly protect you. I say 'partly,' because even if your lungs and mucous membranes in the mouth and nose were protected in low concentrations of the gas, your eyes and skin are not. If it's a high concentration, you can see and smell it coming, so you get a chance to run. Of course, if you're stuck in a high concentration of chlorine gas, you're pretty much boned.

Oh, and the ammonia neutralizing chlorine is also not true.

Hey man, you want a hit of this? This stuff'll melt the testicles off a monkey
