Antacids: Types, Precautions, Side Effects & More

Calcium carbonate is an antacid that works by lowering the amount of acid in the stomach. Simethicone works by breaking up gas bubbles in the gut. This medication is used to treat the symptoms of too much stomach acid such as stomach upset, heartburn, and acid indigestion.

Drugs such as Reglan® speed up the digestive process. This decreases the amount of stomach acid that splashes back into the esophagus. Prescription-strength acid blockers. In prescription strength (usually higher doses), Zantac, Tagamet, Pepcid, and Axid can generally relieve heartburn and treat GERD. GERD may also lead to esophageal stricture, a narrowing of the esophagus that makes it hard to swallow.

This is done through an acid/base chemical reaction, which is shown in Equation 1 below. Leonard, Jayne. “Does baking soda work as treatment for acid reflux?.” Medical News Today. MediLexicon, Intl., 4 Sep. 2018. Web.

Alka Seltzer is an antacid commonly ingested to neutralize stomach acid and provide relief from gastric distress. Rather than ingest a solid Alka Seltzer tablet, you should dissolve the tablet in water, which produces a characteristic fizz. What you might not realize is that a chemical reaction is actually taking place. You can simulate what happens in the stomach when a person consumes Alka Seltzer by mixing a tablet with hydrochloric acid and observing the resulting chemical reaction.

What are antacids?

the stomach. In other conditions where it is helpful to neutralise stomach acid. For example, for occasional bouts of indigestion (dyspepsia). Aluminum Hydroxide [Al(OH)3] – Compared to magnesium hydroxide, aluminum hydroxide is a weak, slow-acting antacid, and its acid-neutralizing effect varies among commercial products. Sodium bicarbonate [NaHCO3] – Sodium bicarbonate is a weak, short-acting antacid.

Antacids are typically safe for most people. However, people with certain medical conditions should talk with their doctors before taking certain antacids that contain aluminum hydroxide and magnesium carbonate.

Because the esophagus is usually at a neutral pH, it is not used to dealing with such an acidic solution. Consequently, during acid reflux the stomach acid irritates the esophagus, causing the common feeling of heartburn. Heartburn is most commonly a pain felt in the chest and usually, but not always, results from acid reflux.

They are traditional, cheap, handy, and relatively safe – although they are not without risks and side effects can occur. Antacids that contain both magnesium and aluminum – like Maalox and Mylanta – are less likely to cause diarrhea or constipation than products containing just magnesium or aluminum, since the effects of these two ingredients tend to balance each other out. If you’re pregnant, take care to avoid antacids that contain sodium bicarbonate – like Alka-Seltzer – or are otherwise high in sodium. They work by neutralizing the stomach acid that irritates the stomach and esophagus. Chemically, sodium bicarbonate is a base that consumes and neutralizes acid.

Non-particulate antacids (sodium citrate, magnesium trisilicate) increase gastric pH with little or no effect on gastric volume. This article is about the medication used to relieve heartburn. For the acid produced by ants, known in many languages as “ant acid”, see Formic acid. Antacids should be used when you have symptoms or think you will get them soon – for most people, the best time to take them is with or soon after meals, and just before going to bed.
