Sounds like it comes with an increased risk of stroke and cardiological issues, psychomotor agitation, anxiety, aggression, possibly even psychosis. Humans have noradrenaline regulation for a reason.
We'll have to see. There are a lot of natural and experimental painkillers that aren't used either because of side effects or more often because they just don't work consistently. It just so happens that so far the opioids are the only ones that can handle extreme pain. It's a hard problem to solve
Prediction: It will end up being used by the military and/or fighters to provide instantaneous muscle strength coupled with pain relief from overexertion.
With soldiers it makes sense to use it explicitly to enforce the "fight" mode as needed. This can range from "occasionally in emergencies" to "all the time".
But militaries have famously not cared about the long term health and well being of their forces past their active use. So any consequence of "long term fight mode" past victory day are just the cost of doing business.
It is hard to beat morphine and its derivatives (eg fentanyl). In strict medical settings they are excellent analgetics and anxiolytics, safe with minor side effects. The only problem is when things go wary after the initial use (dependence etc).
I can't find the study about this compound, Discovery and development of an oral analgesic targeting the α2B adrenoceptor, anywhere. I'd like to read more about the clinical pharmacology in detail.
