U.S. regulators in 2020 pulled all brand-name Zantac and generic versions off the market, triggering a wave of lawsuits.GSK on Wednesday said the settlement reflected its "desire to avoid distraction related to protracted litigation." It did not admit any liability, and said it would vigorously defend itself in any other Zantac cases.
