Traditional psychopharmacotherapy involves symptom suppression: in other words, treating symptoms of the condition such as anxiety or depression. Typically, these medicines are taken on an ongoing basis.
Typically, this form of treatment includes a limited number of doses coupled with psychotherapy, which seek to heal a psychological injury and help to target the root cause.
On the other hand, this form of treatment typically includes a daily regimen of medicine in order to target the symptoms. If medicine stops being taken, then it is possible for symptoms to return.
30-50% of clients do not respond to available treatments, including anti-depressants (Husain et al., 2023).
