With tossed to the trash heap of history, there is a void in the market for a new diet drug. That void apparently will not be filled by Arena Pharmaceuticals’ new drug lorcaserin. The FDA rejected the drug last week. The problem with lorcaserin was a big one: it caused the formation of cancer in rats, albeit in high doses.
There is obviously big demand for a diet drug that works and has limited side effects. Eventually, modern science is going to produce such a drug and extreme obesity will be a thing of the past. Arena Pharmaceuticals probably would tell you that while not a panacea, we are getting closer with lorcaserin and they will be able to prove it is both safe and effective. History gives us doubts.
