Rimonabant is a fairly new treatment which is known as a cannabinoid receptor antagonist, which effectively means that it works on the areas on the brain which control food intake, and suppresses the craving for food. While the treatment has been proved to be effective, there has been mixed feedback with some users reporting bouts of depression.
Ultimately this type of treatment will probably prove more popular in the future, however there is currently a degree of caution from the market because Rimonabant manipulates the central nervous system and brain. As more research is completed the long term side effects should become clearer. Alternatively, you can also try other weight loss treatments by using best diet pills.
