    While Europe is no slam dunk, but when it happens, expect a major short squeeze and it could come the week of April 22.

    The issues in questions to Arena were the same ones the FDA had and which Arena was able to show were statistically insignificant or that Belviq actually helped. E.g., patients with preexisting valvulopathy improved 19% over the placebo group.

    Sales for Belivq will be much better than for Qsymia. I am saddened that people still compare them in the same breadth. They are very different in their safety profile and most factors affecting marketability. This can be visualized in a side-by-side comparison found here:

    A recent analysis found that the Qsymia formulation of 2 generic drugs never had a chance. The idea for Q appears to have come from bariatric physicians who have a long-standing practice of prescribing the parts of Q on the cheap. Changing that practice to sell Q will only cost them. Since Q contains phentermine, an amphetamine, other doctors appear reluctant to prescribe it.

    Understanding why the door is wide open for Belviq and not to Qsymia is easily understood after reading research in the journal "Obesity" entitled, "How physician Obesity specialists Use Drugs to treat Obesity" at

    If investors did, they would buy ARNA because Belviq fits in with doctor practices whereas Qsymia does not. Q will have a time and place, but I would not expect it for at another year.
