Exhibiting antibacterial and gastroprotective properties, bismuth subsalicylate is an insoluble salt of [salicylic acid] linked to trivalent [bismuth cation]. Each molecule of bismuth subsalicylate contains 58% bismuth and 42% salicylate by weight. Bismuth subsalicylate has been around for over 100 years: it was originally developed in 1901 for hygienic use and sanitation for cholera infection.  Bismuth subsalicylate was first approved by the FDA in 1939 and is now mainly used to relieve nausea, diarrhea, and gastrointestinal discomfort. It is an active ingredient found in Pepto-Bismol, a common over-the-counter medication that is used to temporarily treat discomforts of the stomach and gastrointestinal tract. Bismuth subsalicylate is a component of HELIDAC Therapy (bismuth subsalicylate, [metronidazole], and [tetracycline]), which is a treatment regimen indicated for the eradication of H. pylori for treatment of patients with H. pylori infection and duodenal ulcer disease."}]
