Sucralfate, metronidazole, and lignocaine are often combined to treat gastrointestinal issues like ulcers and gastritis. Sucralfate forms a protective barrier over ulcers, metronidazole fights Helicobacter pylori bacteria, and lignocaine relieves associated pain. This combination offers a comprehensive approach to treating these conditions. As with any medication, following healthcare professional guidance and being aware of potential side effects or interactions is crucial.
