Researech finds that the untested drug, Citalopram, a medication commonly prescribed to children with autism spectrum disorders (ASD), was no more effective than a placebo at reducing repetitive behaviors, according to researchers funded by the National Institute of Mental Health (NIMH) and other NIH institutes. The study is published Archives of General Psychiatry.

“Parents of children with autism spectrum disorders face an enormous number of treatment options, not all of which are research-based,” said NIMH Director Thomas R. Insel, M.D. “Studies like this help us to better understand which treatments are likely to be beneficial and safe.”

The researchers say their findings do not support using citalopram to treat repetitive behaviors in children with ASD. Also, the greater frequency of side effects from this particular medication compared to placebo illustrates the importance of placebo-controlled trials in evaluating medications currently prescribed to this population.

Citalopram is in a class of antidepressant medications called selective serotonin reuptake inhibitors (SSRIs) that is sometimes prescribed for children with ASD to reduce repetitive behaviors. These behaviors, a hallmark of ASD, include stereotypical hand flapping, repetitive complex whole body movements (such as spinning, swaying, or rocking over and over, with no clear purpose), repetitive play, and inflexible daily routines.

Researchers in the Studies to Advance Autism Research and Treatment (STAART) network, funded by five NIH institutes, conducted a six-site, randomized controlled trial comparing the effectiveness and safety of using the SSRI citalopram (Celexa) versus placebo to treat repetitive behaviors in children with ASD. The study included 149 participants, ages 5
