Pharmaceutical litigation refers to legal proceedings involving claims or disputes related to drugs, medications, and pharmaceutical products. This can include lawsuits filed by individuals who have been injured by a defective drug, class action suits against manufacturers for false advertising or failure to warn consumers of potential side effects, and other legal actions seeking compensation for harm caused by pharmaceuticals. The phrase is often used in the context of product liability law, where companies are held responsible for the safety and efficacy of their products.
