Schizophrenia treatment could go from daily pills to four shots a year

This early-phase study tested a new long-acting injection of the antipsychotic drug risperidone that would only need to be given once every three months. Fifty-eight adults with stable schizophrenia received a single shot at different doses to measure how the drug moves through the body and to check for safety issues. The goal is to see if this quarterly shot could eventually offer a more convenient option for people who currently take daily risperidone pills.
