July 6, 2010 updated by: Hospital Authority, Hong Kong
The purpose of this study is to evaluate the efficacy, tolerability and safety of patients on long-acting Risperidone microshpheres injection. The major advantage of long-acting injection over oral medication is facilitation of compliance in medication taking. Non-compliance is very common among schizophrenic and is a frequent cause of relapse.
