The drug effectively treats the explosive and aggressive behavior that can accompany autism. The change can be dramatic, he says, taking effect in a matter of weeks. Through these effects, risperidone allows children with autism to benefit from social services, educational programs and behavioral interventions, experts say.
But risperidone also has significant drawbacks and limitations. Children taking risperidone gain an average of 6 pounds within eight weeks of taking the drug. The drug can also cause drowsiness, hormonal changes and, in rare cases, involuntary movements. Aripiprazole, the only other drug approved to treat irritability in autism, has similar side effects.
The FDA approved it for children with autism in And a clinical trial designed to evaluate the safety and efficacy of an extremely low dose of risperidone yielded disappointing results last year.
It was initially developed to treat schizophrenia. Older antipsychotics, most notably haloperidol, also work by dampening dopamine activity. Ina randomized clinical trial of children with autism between 5 and 17 years of age showed a 57 percent reduction in tantrums, aggression and self-injury after taking risperidone, compared with a 14 percent reduction in children taking a placebo.
Among the children who responded positively to the drug, nearly 70 percent still showed improvements after six months of taking it. This January, researchers published a new analysis of the data, in which they classified the participants by the type of aggressive behavior they showed — hotheaded aggression in response to provocation versus unprovoked aggression, for example.
Risperidone significantly improved symptoms in all these subgroups, the researchers found. The challenge is to figure out how to maintain these benefits while minimizing the risks.
Researchers randomly assigned children with autism to one of three groups. The lower dosage did decrease several side effects, including sleepiness and increased appetite, the researchers reported in a paper. Unfortunately, the dose was no more effective than a placebo in alleviating irritability.
Weighty decision The researchers also found that after six weeks of taking a standard dose of risperidone, children had greater increases in insulin levels and insulin resistance than children taking a placebo.
Weight gain and the resulting metabolic problems are side effects of nearly all antipsychotic drugs, but rapid weight gain can be especially worrisome in children. They found that these records mentioned sleepiness less frequently than weight gain, but the former is often the reason that families take children off the drug.
High levels of the hormone can have a feminizing effect, causing breast development in boys and lactation in girls, as well as problems with menstruation and sexual dysfunction.
There needs to be much more research on the effects of chronically elevated prolactin levels, especially in children and teens, they say. In the final analysis, researchers say risperidone should be given with caution, only for children with the most serious symptoms and only after other treatments have failed.
