It is unfortunate that it led to this, but Rimonabant interacts with the central nervous system which is an area of the human body that varies greatly
from person to person. So, in clinical trials for such drugs results can vary greatly from one test subject to the next and results are often
inconclusive. Laws governing the introduction of medications also vary from country to country and this is why Rimonabant never really made it
through FDA scrutiny in the United States. For anyone knocking the FDA (which happens quite a bit on this board), they are one of the better
organizations in the world for the rigorous testing and clinical information they require before medications enter the U.S. market. You can read a
bit more about it here:
FDA: Rimonabant
If I remember correctly the manufacturer of Rimonabant is Sanofi-Aventis who is one of the biggest pharmaceutical companies in the world, or at least
in Central Europe. Their plan for introduction of the drug into the United States failed because of the number of reports that suggested its
potential harm to the nervous system and interfering with human physiology which lead to a number of mental conditions. Back when the drug was first
being tested and in the trial stages, there were huge demands for the drug to enter the market. Physicians and patients were eagerly awaiting the
release of Rimonabant...hands out and mouth drooling. Now, pharmaceutical companies are a business, and the key to running any successful business is
to maximize profit and minimize loss. I would tend to believe that Sanofi-Aventis wanted to maximize profit on the hundreds of millions of dollars
that they poured into Rimonabant; not only the money to manufacture the medication but the money to test it. Due to the huge demand for the
medication by both patients and physicians the medication was pushed into the market a little early, particularly in Europe. The FDA, on the other
hand, scrutinized the noted mental side effects from the medication and realized that early release of the drug into the United States would be
unsatisfactory. For the FDA, I believe they were in a bind; sort of a no win situation...if it was released and side effects were noticed by patients
then the patients would be screaming about why it was released early...if they didn't release it then people would be equally upset about the loss of
a potentially good weight loss medication. However, the drug was approved for sale in Europe by the European Commission. Here is a bit more on the
approval by Forbes Financial:
European Commission approves Acomplia
Due to the fact that results can vary greatly in patient to patient studies involving medications that interact with the central nervous system there
is a grey area concerning their approval.
