A Florida state court last month handed the manufacturers of the heartburn drug Zantac another legal victory by dismissing a plaintiff’s claim that Zantac caused his prostate cancer and finding that the plaintiff’s expert testimony was unreliable.

On Aug. 19, Florida’s 13th Judicial Circuit Court in Hillsborough County issued the order dismissing the lawsuit brought by Edward Wilson against a number of pharmaceutical companies, including GlaxoSmithKline Holdings (GSK) and Boehringer Ingelheim Pharmaceuticals Inc.

The dismissal followed the court’s decision days earlier to exclude the plaintiff’s expert witness testimony, which attempted to link ranitidine, the stomach acid reducer in Zantac, to an increased risk of prostate cancer. In a statement provided to the Florida Record, GSK welcomed the decision written by Judge Darren Farfante.
