I presume the antacid is being used for heartburn. Prescription and over the counter acid blockers (e.g. Nexium, Tagamet, etc.) block the production of acid and don't rely on calcium to buffer. They are not recommended for long term use, however, due to adverse side effects.
Regular over-the-counter antacids in tablet form usually contain some sort of alkyline material to neutralize acids, and calcium is found in many of these substances. However, there are calcium-free over-the-counter antacid tablits too.
Interestingly, deglycyrrinized licorice (DGL, in lozenge or powder form) is a more natural compound that appears to be effective in calming heartburn. DGL coats the GI tract, acting as a physical buffer once stomach acid has started to make its way up GI tract. DGL can interact with some medications, so it is best to take under the advice of a licensed naturopathic doctor.
Keep in mind that in many cases, eliminating food sensitivities can completely reverse chronic episodic heartburn, which means a person wouldn't have to worry about antacids at all.
An antacid contains hydroxides of magnesium and aluminium, bicarbonates of calcium and sodium.
The main ingredient in antacid tablets is calcium carbonate, also known as calcite or chalk. Calcium neutralizes the acid when taken.
Calcium Carbonate
what is a chemical change that could happen to an antacid tablet
base.
Tums, it contains calcium carbonate
An antacid usually contains some sort of base. One antacid, milk of magnesia, is magnesium hydroxide. Other antacids include aluminum hydroxide, sodium bicarbonate, and potassium bicarbonate.
A common compound in antacids is calcium carbonate. Sodium bicarbonate is also an antacid.
Calcium carbonate. It combines with excess acid to produce water.
Tums is an antacid that is manufactured by GlaxoSmithKline. It is available over the counter for the treatment of acid indigestion and heartburn. The scientific name for Tums is calcium carbonate antacid.
rolaids is the best Calcium Carbonate antacid. i just did a lab on this
Which ever one has the most Ca2C03, or calcium carbonate.
