The research study on the effects of Quetiapine on Anorexia Nervosa is a double-blind placebo controlled single group trial sponsored by the University of California, San Diego (UCSD) and University of South Florida. It is currently recruiting participants to help in the determination of Quetiapine’s effect on anorexia nervosa. As it is a double-blind placebo clinical trial, both participants and researchers will not be aware of who is receiving the actual medication and who is receiving placebos (inactive substances usually in the form of sugar pills) in order to avoid tainting the study with bias from either parties.The study was started in July 2006 and is expected to be concluded by May of 2009. The primary purpose of the study is to determine whether the medication Quetiapine, aside from its body mass index increasing effect, can help symptoms of anxiety, depression, and obsessionality found in cases of anorexia nervosa.
