Lunesta maker gets name change

MARLBOROUGH, Mass. The maker of a popular prescription sleeping pill is getting a name change.

Sepracor said Thursday that it would change its name to Sunivion Pharmaceuticals. The company, which Dainippon Sumitomo Pharma Co. acquired in October, makes the sleeping drug Lunesta (eszopiclone).

“The post-merger integration progressed very smoothly and was completed earlier than expected,” DSP president and CEO Masayo Tada said. “Therefore, in April 2010, we merged [Dainippon Sumitomo Pharma America], our other U.S. subsidiary, with and into Sepracor.”
