Some antacids have been used in the treatment of constipation and diarrhea.
Currently marketed antacids contain salts of aluminum, calcium, magnesium, or sodium.
Some preparations contain a combination of two salts, such as magnesium carbonate and aluminum hydroxide.
Medical uses
Antacids are available over the counter and are taken by mouth to quickly relieve occasional heartburn, the major symptom of gastroesophageal reflux disease and indigestion.
Treatment with antacids alone is symptomatic and only justified for minor symptoms.
Antacids do not directly inhibit acid secretion, and thus are distinct from acid-reducing drugs like H2-receptor antagonists or proton pump inhibitors
Antacids do not kill the bacteria Helicobacter pylori, which causes most ulcers
Non-particulate antacids (sodium citrate, magnesium trisilicate) increase gastric pH with little or no effect on gastric volume, and therefore may see some limited use in pre-operative procedures.
Sodium citrate should be given within 1 hour of surgery to be the most effective
Side effects
Formulations containing magnesium salts may cause diarrhea, whereas those containing calcium or aluminum may cause constipation.
Rarely, long-term use may cause kidney stones.
Long-term use of antacids containing aluminum may increase the risk of developing osteoporosis.
Mechanism of action
When excessive amounts of acids are produced in the stomach, the natural mucous barrier that protects the lining of the stomach can damage the esophagus in people with acid reflux.
Antacids contain alkaline ions that chemically neutralize stomach gastric acid, reducing damage to the stomach lining and esophagus, and relieving pain
Formulations and brands
Antacids may be formulated with other active ingredients such as simethicone to control gas, or alginic acid to act as a physical barrier to acid
Effervescent tablets
Effervescent tablets are tablets which are designed to dissolve in water, and then release carbon dioxide
Common ingredients include citric acid and sodium bicarbonate, which react when in contact with water to produce carbon dioxide.
Effervescent antacids may also contain aspirin, sodium carbonate, or tartaric acid
Common brands include Alka-Seltzer, Eno and Andrews.
Algeldrate
Wyeth Amphojel tablets of aluminum hydroxide.
Under the generic name algeldrate, aluminium hydroxide [Al(OH)3] is used as an antacid.
Aluminium hydroxide is preferred over other alternatives such as sodium bicarbonate because Al(OH)3, being insoluble, does not increase the pH of the stomach above 7 and hence, does not trigger secretion of excess stomach acid.
Brand names include
Alu-Cap,
Aludrox,
Gaviscon,
and Pepsamar.
In 2016 Gaviscon was one of the best-selling branded over-the-counter medications sold in Great Britain, with sales reaching £62 million.
Aluminum hydroxide reacts with excess acid in the stomach, reducing the acidity of the stomach, which may relieve the symptoms of
ulcers,
heartburn
or dyspepsia.
Such products can cause constipation, because the aluminum ions inhibit the contractions of smooth muscle cells in the gastrointestinal tract, slowing peristalsis and lengthening the time needed for stool to pass through the colon.
Some such products are formulated to minimize such effects through the inclusion of equal concentrations of magnesium hydroxide or magnesium carbonate, which have counterbalancing laxative effects.

PEPTO-BISMOL
medicine for “indigestion”
(pepto-bismol)
(“bismuth subsalicylate”)
(soothes symptoms?)
(that doesn’t appeal to me)
(heartburn / indigestion / upset stomach / nausea / diarrhea)
(30ml / 2 tbsp every hour)
(don’t use more than 4 doses per day)
(don’t use more than 2 days)
it’s a mystery to how pepto-bismol actually works…
(“coats” irritated tissues?)
