Treatment with once-monthly INVEGA® SUSTENNA(TM) is not inferior to treatment with bi-weekly RISPERDAL® CONSTA®, according to new data from a comparative study of both treatments in patients with schizophrenia. Results of the 13-week clinical trial were released this week.
An estimated one percent of the world's population suffers from schizophrenia - a brain disorder that impairs a person's ability to think clearly, relate to others, and distinguish between reality and imagination. In the U.S., approximately 2.4 million Americans have schizophrenia, with men and women affected equally. Non-adherence to medication treatment is a common problem encountered in patients with schizophrenia, which can lead to relapse (an increase in symptoms) and hospitalization. Since both INVEGA SUSTENNA and RISPERDAL CONSTA are given by a healthcare professional, it offers the physician a way to monitor patient medication adherence and intervene when a patient misses a dose. Both products offer flexibility to physicians and patients, based on their dosing regimens, thereby offering an important option to those who may need it.
