An Introduction to Bismuth Subsalicylate

Bismuth may have been used internally in Europe in the late 1700s, its effectiveness as a treatment for spasmodic discomfort in the stomach and bowels. Soon after, Chambers in the UK and Kussmaul in Germany reported that bismuth salts were a successful medication for dyspepsia. A New York physician created a liquid preparation containing bismuth subsalicylate and zinc salts for astringency, salol (phenyl salicylate) for antiseptic capacity, oil extracts of the wintergreen plant for flavour, and a red dye to create the item pink in an attempt to treat children.


Bismuth subsalicylate is a colloidal compound achieved by hydrolysis of bismuth salicylate with the empirical chemical formula C7H5BiO4. So, this article gives a deep view of knowledge on bismuth subsalicylate and its characteristics.


What is Bismuth Subsalicylate?

An antacid elixir medicine known as bismuth subsalicylate, also known by the trade names Pepto-Bismol and Bis-Bacter, is utilised to treat short-term stomach and gastrointestinal tract aches and pains like nausea, diarrhoea, heartburn, digestive problems, and stomach-ache. Pink bismuth is the generic version of the bismuth subsalicylate medicine.


Bismuth Subsalicylate Medicinal Uses

Bismuth subsalicylate medicine belongs to the class of medications known as antidiarrheal agents. Bismuth subsalicylate medicine, a salicylic acid derivative, does have anti-inflammatory and bactericidal properties. It also functions as an antacid. It operates by lowering the stream of fluids and electrolyte levels into the bowel, reducing inflammation, and possibly killing the organisms that trigger diarrhoea.


Bismuth Subsalicylate Action Mechanism

Bismuth subsalicylate medicine is presumed to be a combination of the ones that follow:

  • Intestinal wall stimulation of fluid and electrolyte absorption.

  • As a salicylate, it reduces gastrointestinal and intestinal liner inflammatory processes by inhibiting prostaglandin G/H synthase 1/2.

  • Reduced stomach harms caused by Escherichia coli.

  • A quantity of its constituents, such as salicylic acid, has bactericidal activity.

  • Bactericidal action is achieved through an oligodynamic influence in which tiny constituents of heavy metals like bismuth harm numerous distinct bacteria species.


Warnings

The bismuth subsalicylate warnings are as follows:

  • If people possess bleeding issues, a gastric ulcer, bleeding in their stools, or if they are sensitive to aspirin or other salicylates, then they shouldn't use bismuth subsalicylate.

  • If a child or teen suffers from chicken pox, the flu, or a fever, then this medication shouldn’t be given.

  • Inquire with a physician or pharmacist if using this medication is safe if one possesses mucus in their stools or perhaps a fever right now.

  • If a person is pregnant or breastfeeding, they should consult a doctor before utilising this medication.

  • Without first consulting a doctor, never administer this medication to a kid under the age of 12.


Bismuth Subsalicylate Dosages

  • Patients might not be on a bismuth subsalicylate dosage plan because bismuth subsalicylate is taken as required. If it is nearly up for the subsequent dosage, the patient can ignore the missing bismuth subsalicylate dosages. But never combine two doses at once.

  • Patients should not consume more than 8 bismuth subsalicylate doses each day.

  • If a person takes overdosage, then they will need immediate medical help or dial the poison helpline.

  • Fatigues, despair, anxiety, irritability, issues with balancing or cooperation, disorientation, tremor, or abrupt muscular contractions are a few examples of overdose symptoms.


Bismuth Subsalicylate Side Effects

Some of the bismuth Subsalicylate side effects are as follows:

  • Hives, wheezing, trouble to breathe, and swelling on the lips, tongue, throat, or face are all indications of an allergic reaction.

  • Behavioural alterations accompanied by vomiting and nausea.

  • Impairment of hearing or ringing in the ears.

  • Diarrhoea that lasts more than two days.

  • Gastrointestinal condition gets worsened.


Interesting Facts

  • In regions of the world like North America currently, bismuth subsalicylate is among the most popular stomach medications.

  • Anticoagulation treatments, such as Coumadin, and bismuth subsalicylate usage are associated with an elevated incidence of bleeding.

  • After taking a single 30-mL dose of bismuth subsalicylate, which includes 525 mg of bismuth subsalicylate, bismuth is still detectable in gastrointestinal mucosal samples for up to 6 hours, according to studies in dogs.

  • The cytoprotective effects of bismuth subsalicylate could in fact be attributed to this interaction of bismuth with the gastric mucosal surface.


Key Features to Remember

  • With the widespread use of bismuth subsalicylate and its financial importance, the pharmaceutical's precise composition was unknown for a long time.

  • However, using cutting-edge electron crystallographic methods, it was discovered to be a multilayer copolymer with the formula C7H5BiO4.

  • Bismuth subsalicylate sometimes causes black or blackened tongues. This adverse consequence is unharmful.

  • Some of the possible side effects include constipation or dark stools.

  • Medicine should be preserved away from the access of kids and firmly shut in the original container. It should be kept at a normal temperature, free from sources of extreme moisture and heat.

FAQs on Bismuth Subsalicylate

1. Explain the coordination of the structure of bismuth subsalicylate?

The salicylate's carboxylate and phenol groups coordinate with the bismuth cations in the molecule. Small particle size and structural flaws brought on by differences in the stacking order of the bismuth subsalicylate units, which may be seen as a component of the structure examination, have often prevented the identification of bismuth subsalicylate.

2. What is the chemistry of bismuth subsalicylate in the gastrointestinal tract?

Bismuth subsalicylate is a salt of salicylic acid and trivalent bismuth that is incredibly insoluble. Every molecule has a weight percentage of 42% salicylate and 58% bismuth.

3. Explain the hydrolysis of bismuth subsalicylate in the stomach?

 It is believed that bismuth subsalicylate is almost entirely hydrolyzed in the stomach to produce salicylic acid and bismuth oxychloride. According to the outcomes of in vitro experiments using simulated gastric juice, bismuth subsalicylate is quickly hydrolyzed at pH levels below 3.
