A Philadelphia judge said an appeal by Wyeth Pharmaceuticals of her decision not to dismiss digestive drug products liability claims filed against the drugmaker at the preliminary objections stage should be quashed.

Around 2,000 plaintiffs have filed lawsuits against Wyeth, which is owned by Pfizer, as well as several other defendant drugmakers alleging that their use of metoclopramide caused them to have an incurable neurological disorder called tardive dyskinesia, according to court papers.
