About blonanserin (brand name in Japan: LONASEN^®)

Blonanserin is an atypical antipsychotic agent with novel structure, discovered by Dainippon Sumitomo Pharma. This product is characterized by its strong blocking action and high selectivity against dopamine-2 receptors and serotonin-2 receptors. It has stronger blocking action to dopamine-2 receptors than to serotonin-2 receptors. Consequently, this drug has been found to improve not only positive symptoms of schizophrenia (such as hallucinations and delusions), but also negative symptoms (such as flat affect and hypobulia). In Japan it is available from DSP since April 2008 for the treatment of schizophrenia.
