Bismuth subcitrate potassium is a salt of bismuth (Bi 3+), potassium (K +) and citrate (C 6 H 4 O 7 4−) in a molar ratio of about , with 3 moles of water. It contains about % (mass percent) bismuth, which is the active moiety, and % potassium. Other sources give somewhat different ratios of . Notably, most of the bismuth salts are inexpensive Lewis acid, non-toxic, and readily available reagents. In view of the rapidly expanding field of bismuth salts-mediated reactions and significant attention in this area from academic and industrial scientists, an issue of a journal on organobismuth mediated reactions would be necessary and timely.
Bismuth is a chemical element with the symbol Bi and atomic number It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter group 15 siblings arsenic and tal bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead. Background and Methods: The antibacterial activity of originally devised and synthesized organobismuth compounds was tested against fresh clinical isolates of Helicobacter pylori and compared with clinically well-established inorganic bismuth salts currently used in triple antibacterial treatment to eradicate H. test conditions in vitro were standard for determination of minimum.

Bismuth salts, both organic and inorganic, have been used medicinally to treat a variety of infectious diseases, gastrointestinal disorders, and dermatological h-based radiocontrast media are used in diagnostic medicine.
Bismuth salts, including ranitidine bismuth citrate, colloidal bismuth subcitrate, and bismuth subnitrate appear to be safe when taken in doses of mg daily for up to 56 days. Recently published data showed that adding bismuth salts to a triple therapy of proton pump inhibitors, amoxicillin and clarithromycin helped eradicate Helicobacter pylori infection.
Javier P. Bismuth salts, including ranitidine bismuth citrate, colloidal bismuth subcitrate, and bismuth subnitrate appear to be safe when taken in doses of mg daily for up to 56 days. Bismuth is POSSIBLY UNSAFE when taken by mouth in large amounts due to the risk for kidney failure, and when taken over the long-term due to the risk of nerve damage.
Bismuth subsalicylate, sold as generic and under the brand name Pepto-Bismol, is an antacid elixir medication used to treat temporary discomforts of the stomach and gastrointestinal tract, such as nausea, heartburn, indigestion, upset stomach, and is also commonly known as pink bismuth, but Pepto-Bismol has become a genericized trademark for the substance.
INTRODUCTION. Bismuth salts have been used for centuries in medicine. From a gastroenterology perspective these drugs have been used to treat peptic ulcer disease, dyspepsia, parasitic infections, microscopic colitis, and infectious diarrhoea.The discovery of Helicobacter pylori (H pylori) in by Warren and Marshall revolutionised the management of peptic ulcer disease, and.

A bismuth salt of salicylic acid. Little absorbed from the gastrointestinal tract, bismuth subsalicylate exerts a local effect on the gastric mucosa, coating it and protecting it from the corrosive effects of acid and pepsin. This agent also has local antimicrobial properties.

Some intact BSS passes unchanged into the duodenum, where it can react with other anions such as bicarbon- ate and phosphate to form bismuth subcarbonate and bismuth phosphate salts.
The salicylate released from. Background & aims: Due to the poor eradication rates of standard triple therapy, the addition of bismuth salts has been proposed for first-line eradication of Helicobacter pylori.
We assessed the effectiveness and safety of the combination of bismuth and the standard, clarithromycin-containing triple therapy in eradication of H pylori infection, using data from a large multi-center registry.
Bismuth subsalicylate (BSS) has been used for more than 80 years to treat gastrointestinal symptoms although little clinical evidence was available until recently to substantiate its value and possible mechanisms of action. Abstract. Bismuth preparations are used for the treatment of various gastrointestinal disorders [1–3].
Various bismuth salts have recently become available for the treatment of Helicobacter pylori related gastroduodenal diseases [4–6]. Despite several beneficial effects of bismuth on the gastroduodenal mucosa, the antibacterial effect against H.

Jun;47() [Article in Undetermined language] Author A COUSYN. PMID: No abstract available. Bismuth salts have been used for centuries in medi-cine. From a gastroenterology perspective these drugs have been used to treat peptic ulcer disease, dyspepsia, parasitic infections, microscopic colitis, and infectious diarrhoea.
The discovery of Helicobacter pylori (H pylori) in by Warren and Marshall revolutionised the man. The meta-analysis also included RCTs evaluating bismuth-based quadruple therapy as secondary treatment, which found cure rates averaging 78%.
1 The regimens varied, comprising bismuth salts ( mg, times daily), metronidazole ( mg, times daily), tetracycline ( mg, times daily), and a PPI (40 mg twice daily).
Longer duration of therapy produced higher cure rates. Bismuth subsalicylate (Pepto-Bismol) is the only colloidal bismuth salt drug approved for OTC use in multiple GI conditions, including “diarrhea, heartburn, indigestion without constipation, nausea, and upset stomach.” The mechanism of action of bismuth subsalicylate in these gastrointestinal disorders is not completely understood.
Bismuth There are two main types bismuth sibcitrate and bismuth subsalicylate. In the colon, bismuth salts reacts with hydrogen sulfide to form bismuth sulfide, which blackens the stools.
Adverse effects include bismuth intoxication; especially with chronic high dose use of bismuth subgallate. Coadministration of H2RAs increases bismuth absorption from bismuth sibcitrate, but not from bismuth.Get this from a library!
