What I want to note is why anti-inflammatory medication, despite the apparent evidence for its benefit, has not managed to be included in guidelines for depression. To gain approval, a large scale trial would need to be done to show that anti-inflammatory medication offers the prospect of better treatment than current treatments, but would be very expensive. As the editorial says, only drugs with a high likelihood of generating future profit are put through such trials. The editorial goes on:-
In the case of the traditionally used, safe and tolerable anti-inflammatory agents that are already on the market, there is no financial incentive for the pharmaceutical industry to conduct these costly, large-scale RCTs. Rather, they are more likely to fund newly discovered immunotherapies with a poorly characterized safety profile, as such novel immunomodulatory treatments can be patented and monetized.
Unlike the editorial, I am not suggesting government funding for such trials. As I indicated in my review of Ed Bullmore’s book (see previous post), it’s non-sensical to think that depression is a form of inflammation. Any apparent increase in inflammatory markers in depression is far less than inflammatory disease in general, and has non-specific causes rather than being a marker for depressive disease as such (see previous post).
The market for depression has been flooded. The pharmaceutical companies themselves seem to have realised this years ago (see previous post). If people want medication treatment, let’s at least keep it cheap. We should be suspicious of any attempt to make further money out of medication treatment for depression. Marketing and commercial, rather than scientific and therapeutic, interests have always determined which drugs are prescribed.
