Injectable Risperidone Demonstrates Response, Lowers Relapse

With medication compliance is a significant issue in some people who grapple with schizophrenia, drug companies often look toward injectable forms of their psychiatric medications to help with this issue. A new study suggests that an atypical antipsychotic in injectable form looks to be just as effective as its non-injectable counterpart. Patients with psychosis treated early on in the course of their illness with risperidone long-acting injection demonstrated high response and remission rates with low relapse rates according to the study.

A reduction of the Positive and Negative Syndrome Scale (PANSS) total score of at least 50% was experienced by 84% of the 51 patients included in the study, with only four of these patients relapsing by the study endpoint. During the two-year trial period, the study also showed 64% of patients achieved remission.

Non-compliance or partial compliance remain key barriers in the management of schizophrenia and are often significant contributing factors in relapse. Relapse is associated with increased risk of hospitalization and a dramatically poorer quality of life. Patients experiencing numerous relapses are at high risk of never regaining previous levels of functioning.
