This is still the old news of propranolol, which they're still trying to find a use for in trauma as it's a massive market worth billions of dollars per annum.
Propranolol failed in military trials as a beta blocker, giving it to soldiers before going on combat missions to lessen the effect any event would have within the brain. Well... it failed as a majority result.
Because that failed, due to their claims it could block the memory forming if taken as a preventative measure prior to trauma exposure, so have since now taken up round two of the medication in fighting for the trauma market... this time, lets give it during the recall of memories to really do the same thing, except instead of when being faced with the trauma, the exact same thing is being achieved except through recalling it, claiming it reduces the memories impact after being exposed to the drug.
As usual, the media grabs everything and anything and rewords it for marketing potential to an audience of readers. Readers perpetuate it... then just like propranolol's initial media marketing and the best drug to hit the trauma market years ago, it will again die down with minimal results affecting a small minority.
There will be a small minority who will likely jump on it, use it on every client they have and attempt to justify everything back to it... all without the clinical results to back it up.
Right now, this is all media hype, just like its initial release as a pre-trauma memory forming preventative, which failed dismally.
Drugs companies are doing what they do... trying to come up with a drug to fix mental health. Everything to date points away from drugs being a viable solution to mental health treatment as a primary solution... instead they're finding minority results in using them as secondary aids and treating mental health primarily with psychotherapy showing the best results still today.
The biggest hurdle though, which hasn't changed to date, is the person being treated.
