Risperdal Approved for Teens with Schizophrenia
Read more... Schizophrenia Medications
The United States Food and Drug Administration (FDA) has approved the use of Risperdal (risperidone) for the treatment of adolescents (ages 13-17 years old) with schizophrenia. The FDA is asking for more information about the company's schizophrenia treatment. The company did not specify what the FDA is specifically seeking, but said it did not ask for additional studies. The manufacturer, Johnson & Johnson, will be updating the prescribing information for Risperdal accordingly.
This process of Risperdal approval for teens seems like more of a formality as schizophrenia typically develops in the teen years, and Risperdal has been prescribed for over a decade to these people. To our knowledge, no new studies were done for this new extended approval by the FDA. Most likely additional data was requested from J&J by the FDA for this approval. Other anti-psychotic medications manufacturers like Bristol Myers (makers of Abilify) have also requested approval for use of their medications in teens - and those requests will, we expect, be forthcoming.
Below is the press release from Johnson & Johnson which includes some side-effect information about the use of Risperdal.
FDA Issues Approvable Letter for Risperdal to Treat Adolescents with Schizophrenia and Children and Adolescents with Bipolar Mania
Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD) announced it has received an approvable letter from the U.S. Food and Drug Administration (FDA) regarding two supplemental New Drug Applications (sNDA) for RISPERDAL® (risperidone), filed on Dec. 21, 2006. The sNDAs are for the treatment of schizophrenia in adolescents ages 13-17 years and for the short-term treatment of bipolar mania associated with bipolar I disorder in children and adolescents ages 10-17 years, respectively. The FDA has not asked for any additional studies. J&JPRD is currently reviewing the approvable letter and looks forward to finalizing the label with the agency.
