Mass. DA seeks information from Wyeth concerning Protonix


NEW YORK The district attorney’s office in Massachusetts has subpoenaed Wyeth, seeking information and testimony before a grand jury concerning marketing practices and pricing for Protonix, Wyeth’s proton-pump inhibitor for heartburn.

Wyeth has said it is cooperating with the investigation.
