Well, there are things like beta-blockers (https://en.wikipedia.org/wiki/Beta_blocker), but the thing about emergencies is that they're fast enough that there's not time to pop some pills, much less wait for them to be digested & metabolized & take effect. The whole OP covers, what, 15 minutes it said? The only way beta-blockers might help is if one took them in advance, and they're not perfect side-effect-wise.
Interesting. Things like cocaine (I'm led to believe) act very quickly. I was even thinking that the placebo effect could be leveraged somehow. Perhaps popping a pill that resides in your top pocket could be a first response whenever a situation starts getting a little hairy.
I honestly think it's worth investigating. Why put up with having your stress response decimate your cognitive abilities, especially when you need them most?
