bismuth subnitrate

Bismuth subnitrate is a highly water-soluble crystalline compound used primarily as an antacid and anti-diarrheic agent. It has been employed in the treatment of duodenal ulcers and gastrointestinal disorders due to its supposed antacid and mildly astringent actions. Bismuth subnitrate exerts protective effects on the gastric mucosa by forming a barrier over ulcer sites and may also disrupt bacterial cell walls, inhibit bacterial enzymes critical for survival, and prevent bacterial adherence to the gastric lining. It is approved by the FDA for use as an active ingredient in over-the-counter antacids. Additionally, it has topical applications for skin disorders, wounds, burns, hemorrhoids, and other anorectal conditions[1][2][4][5].
