What is "blonanserin"

n. An atypical antipsychotic for the treatment of schizophrenia.

Blonanserin (Lonasen) is a relatively new atypical antipsychotic (approved by PMDA in January 2008) commercialized by Dainippon Sumitomo Pharma in Japan and Korea for the treatment of schizophrenia. Relative to many other antipsychotics, blonanserin has an improved tolerability profile, lacking side effects such as extrapyramidal symptoms, excessive sedation, or hypotension. As with many second-generation (atypical) antipsychotics it is significantly more efficacious in the treatment of the negative symptoms of schizophrenia compared to first-generation (typical) antipsychotics such as haloperidol.
