Wasting Away: Prozac Loses Promise as Anorexia Nervosa Fighter
Bower, B., Science News
Psychiatrists often prescribe fluoxetine, or Prozac, to people suffering from the difficult-to-treat, potentially fatal condition known as anorexia nervosa. Yet the medication appears to provide no benefit in treating the eating disorder, a new investigation reports.
Symptoms of anorexia nervosa consist of a refusal to eat enough to maintain adequate body weight, intense fears of gaining weight, and disturbed thinking about food, weight, and body image. The predominantly female ailment often includes a denial of the seriousness of weight loss and refusal to participate in treatment.
In some cases, binge eating and purging occur periodically.
National surveys suggest that about 1 in 1,000 adults develops anorexia nervosa. A higher prevalence, 1 in 100, shows up among teenage girls and young women. The illness frequently occurs with mental ailments, such as depression and obsessive-compulsive disorder, that respond to Prozac treatment. Clinicians had anticipated similar success in treating anorexia with the drug.
The new study, directed by psychiatrist B. Timothy Walsh of Columbia University, may dash that hope. "It makes more sense to focus on nutritional restoration and maintenance and the provision of good psychological treatment," Walsh says.
He and his colleagues present their findings in the June 14 Journal of the American Medical Association.
The researchers studied 93 women, ages 16 to 45, treated for anorexia nervosa between January 2000 and May 2005. Nearly half of them had binged and purged. Participants had regained weight and maintained it at a healthy level for 2 weeks in hospital programs in New York or Toronto.
Walsh's team then randomly assigned 49 of the women to take physician-monitored doses of Prozac for a year. …
