Bismuth drug mechanism of action

Mechanism of action As an antidiarrheal, the exact mechanism has not been determined. Bismuth subsalicylate may exert its antidiarrheal action not only by stimulating absorption of fluid and electrolytes across the intestinal wall (antisecretory action) but also, when hydrolyzed to salicylic acid, by inhibiting synthesis of a prostaglandin responsible for intestinal inflammation and hypermotility Bismuth subsalicylate is in a class of medications called antidiarrheal agents. Bismuth subsalicylate works by decreasing the flow of fluids and electrolytes into the bowel, reduces inflammation within the intestine, and may kill the organisms that can cause diarrhea. Bismuth subsalicylate is available without a prescription Here, we show that three bismuth complexes exhibit distinct mechanisms of urease inhibition, with some differences dependent on the source of the enzyme. Bi(EDTA) and Bi(Cys)(3) are competitive inhibitors of jack bean urease with K(i) values of 1.74 +/- 0.14 and 1.84 +/- 0.15 mM, while the anti-ulcer drug, ranitidine bismuth citrate (RBC) is a non-competitive inhibitor with a K (i) value of 1.17 +/- 0.09 mM Colloidal bismuth subcitrate is very effective in the treatment of gastroduodenal disorders and appears to act via several mechanisms. It has little acid-neutralizing effect and does not affect acid secretion. It is uncertain whether it affects pepsin secretion, but it does inhibit peptic activity Bismuth subsalicylate (Pepto Bismol, Kaopectate, Bismatrol Maximum Strength, and many other brands) is an over-the-counter (OTC) drug used to prevent traveler's diarrhea, and to treat diarrhea, upset stomach, nausea, indigestion, heartburn, and H. pylori infection. Side effects, drug interactions, dosage, storage, pregnancy and breastfeeding safety.

View abstract Bismuth exerts direct bactericidal effect on Helicobacter pylori by different ways: forms complexes in the bacterial wall and periplasmic space, inhibits different enzymes, ATP synthesis, and adherence of the bacteria to the gastric mucosa ConspectusMetallodrugs have been widely used as diagnostic and therapeutic agents. Understanding their mechanisms of action may lead to advances in rational drug design. However, to achieve this, diversified approaches are required because of the complexity of metal-biomolecule interactions. Bismuth drugs in combination with antibiotics as a quadruple therapy show excellent success rates in.

Bismuth subsalicylate may exert its antidiarrheal action not only by stimulating absorption of fluid and electrolytes across the intestinal wall (antisecretory action) but also, when hydrolyzed to salicylic acid, by inhibiting synthesis of a prostaglandin responsible for intestinal inflammation and hypermotility. In addition, bismuth subsalicylate binds toxins produced by Escherichia coli Mechanisms of action of bismuth subsalicylate include antibacterial, antisecretory, and toxin-adsorptive effects. Adverse effects can include black-colored tongue and stools, constipation, and tinnitus

Vd: Bismuth, 170 mL/kg. Metabolism. Stomach: Bismuth subsalicylate is hydrolyzed in stomach to form slightly soluble bismuth oxychloride (BiOCl) and salicylic acid. Small intestine: Unchanged bismuth subsalicylate passes into duodenum and reacts with other anions (eg, bicarbonate and phosphate) to form bismuth subcarbonate and bismuth phosphate.

Systems Approaches for Unveiling the Mechanism of Action

Bismuth compounds are known for their activity against multiple microorganisms; yet, the antibiotic properties of bismuth nanoparticles (BiNPs) remain poorly explored. The objective of this work is to further the research of BiNPs for nanomedicine-related applications. Stable Polyvinylpyrrolidone (PVP)-coated BiNPs were produced by a chemical reduction process, in less than 30 min Synonym—Subnitrate of Bismuth. This salt is formed from purified bismuth, by the action of nitric acid in the presence of distilled water. Physiological Action—It is a mild and soothing agent in its local influence upon the skin and inflamed mucous surfaces. Internally its influence is confined almost exclusively to the gastro-intestinal. Drug Action In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor Bismuth subsalicylate is an over-the-counter medication used for treatment of diarrhea, gas, upset stomach, indigestion, heartburn, nausea and as a prophylaxis for traveler's diarrhea.
