Dainippon Sumitomo Pharma Co., Ltd. (Head Office: Osaka, Japan; President: Masayo Tada) launches "LONASEN® tablets 8mg", new lineup of LONASEN®, an antipsychotic agent (generic name: blonanserin) as of April 26.

LONASEN® is an antipsychotic agent, invented by Dainippon Sumitomo Pharma and first launched in April 2008. Since then, this drug has been widely used in Japan. This drug 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.
