Do you mind if I add a point on that?
In certain drug classes—I'm thinking about mental health or pain, for example—physicians, and you're one, need access to a range of products. Although you'll see some statistics like 80% of these products not adding any additional therapeutic value, often that's at a population level. Some patients do not well tolerate one product, and they need to try something else, especially in mental health, pain management, etc.
There are some very good organizations that are doing comprehensive studies on things like this, and I gather you heard from Dr. Dhalla earlier. The Ontario Drug Policy Research Network does very interesting class reviews. They did one on triptans as well, so I might direct you to that. CADTH does them as well. Those are the places where you can have these discussions in a science-focused way and look at the costs as well.
