Nine multiplaintiff lawsuits accusing major pharmaceutical companies of manufacturing and selling Zantac with high levels of a cancer-causing compound will be heading back to a Connecticut state court after a federal judge concluded that the defendants failed to show there was a “mass action” to trigger federal jurisdiction.

One of those cases was filed by Connecticut resident Beth Bacher, the representative for Paul Bacher, deceased, and 98 other plaintiffs from across the country who also claim they suffered personal injuries or death as the result of using the allegedly dangerous ranitidine-containing products designed and formulated over a 30-year period by the defendants, Boehringer Ingelheim, GlaxoSmithKline, Pfizer and Sanofi-Aventis.
