Gastroesophageal reflux disease (GERD) is a serious condition that is a result of persistent acid reflux that has caused ulcers (open wounds) in the digestive tract. It is often due to a weakened lower esophageal sphincter (LES), the band of muscles that keeps the stomach contents from refluxing up the esophagus. When the LES is weakened it can open at the wrong time or stay open longer than it should. A number of antacids can be used for temporary GERD relief.
Calcium Carbonate
Calcium carbonate is one active ingredient found in some types of antacids. The Mayo Clinic says that this form often comes in a chewable table, some of which taste pleasant. The antacid works by neutralizing acid as it is refluxing up the esophagus and in the stomach. The National Digestive Diseases Information Clearinghouse (NDDIC) points out that while calcium carbonate can also be a supplemental source of calcium, it can lead to constipation.
Mangesium Salt
Magnesium salt is the active ingredient in some types of antacids. Like calcium carbonate, it works to neutralize acid when it comes into contact with the refluxing stomach contents. The NDDIC explains that magnesium salt can contribute to diarrhea. Antacids made with magnesium come in a variety of forms, including liquid, effervescent tablet and effervescent powder.
Aluminum Salt
Aluminum salt is another active ingredient found in some antacids. It is often combined with magnesium salt in one product to counteract the diarrhea caused by magnesium and the constipation caused by aluminum, explains the NDDIC. Like magnesium salt antacids, aluminum salt antacids come in a variety of forms, including liquid, tablet and effervescent products.
