That's an excellent question in terms of why somebody would ask specifically for mefloquine. As far as I can see, there's no literature to look at that question. That would certainly be a good research question to put out there.
You mentioned other drugs, but that they also carry risk. As you mentioned earlier, there could be underlying conditions or a buildup of different events in, for example, a soldier's career where he or she actually hits that point where they break the camel's back and they reach that critical point of PTSD.
With respect to the other drugs, can you speak to the neurological or psychiatric conditions as well as experiences that are potentially traumatic? What are the potential risks with other types of medications that are used for malaria?
