Personally from what I just researched about it, the properties of the medication, nor its desired outcome, would be suitable for the application of PTSD, because anyone trying to suppress the memories are only go to find themselves on a lifetime of drugs, instead of just dealing with the trauma and then getting on with life without the lifetime use of drugs. I am sure the drug companies would push as much as possible in order to attempt avenues of lifelong medication, which they do enough by making medications addictive vs. natural alternatives that do the exact same job, often better because less side effects come from them, and without addictive properties to withdrawal is not an issue.
