Protecto™ is a suspension of sucralfate. Sucralfate exerts a generalized gastric cytoprotective effect by enhancing natural mucosal defense mechanisms. Studies conducted in animals and clinical trials in humans have demonstrated that sucralfate can protect the gastric mucosa against various irritants such as Alcohol, Acetylsalicylic acid (ASA), Hydrochloric acid, Sodium hydroxide or Sodium Taurocholate. In addition, sucralfate has been demonstrated to have a greater affinity for ulcerated gastric or duodenal mucosa than for non-ulcerated mucosa. Sucralfate produces an adherent and cytoprotective barrier at the ulcer site. This barrier protects the ulcer site from the potential ulcerogenic properties of acid, pepsin and bile. Furthermore, sucralfate blocks acid diffusion across the sucralfate protein barrier and also complexes directly with pepsin and bile.
