Acid indigestion

In some studies, over 60% of participants reported adverse gastrointestinal effects of coffee, such as acid indigestion, heartburn, abdominal pain, and symptoms due to gas or constipation. 

Acid indigestion, also known as heartburn, is caused by the excess production of stomach acid. Eating a large meal may bring on acid indigestion. Commercial antacids contain basic salts that neutralize the excess acids. Design a titration experiment to test the effectiveness of various brands of antacids.

The term acid has entered modern speech in terms such as acid rain , acid parties , acid indigestion , etc. These terms are used in conversational language but not in a scientifically correct way. In science we need to define clearly what is meant by acid . Similarly, confusion of terminology has arisen with the word base , e.g. meaning low or bottom, as in the word basement . 

The Pepcid AC case illustrates many of the factors at work in the OTC-switch process. Pepcid AC is by almost every account one of the most successful examples of a prescription drug switched to a nonprescription OTC. The launch of Pepcid AC in the OTC market resulted from a 5-year strategy developed by Merck and Johnson Johnson to market OTC versions of Merck s leading prescription drugs. Prescription Pepcid AC was to be the first case. Originally marketed as a prescription medicine for the treatment of ulcers, Pepcid AC was a reduced-strength version marketed to consumers for the relief of acid indigestion and heartburn.

The same principle applies to acid indigestion. Rather than swallow lye (ugh ) or some other strong base to neutralize excess stomach acid, most people take antacids. Antacids typically contain salts such as calcium carbonate, sodium hydrogen carbonate (sodium bicarbonate), and magnesium carbonate, all of which are salts of weak acids. These... 

Suppose you ve enjoyed too much good food. You have heartburn, acid indigestion, acid stomach—whatever you call it—and you need some relief. Your stomach produces hydrochloric acid along with enzymes to digest food. But sometimes, particularly after a big meal, your stomach produces a bit too much acid. 

The acid-base chemistry of stomach upset is big business. Even if you never use commercial antacids, a lot of other people do. The terms acid indigestion or acid stomach are a bit misleading. You need an acid stomach in order to be healthy. Remember that the pH of stomach acid, which is mostly hydrochloric acid, is about 2.5. 

An alternative approach to controlling acid indigestion is now available in over-the-counter medication. These drugs work by decreasing the secretion of acid in the stomach. These drugs were previously available only by prescription for persons who suffer severe acid indigestion or who have a tendency for gastric ulcers. 

Your stomach is made of protein that is not much different from the protein in a hamburger. The inner walls of your stomach are coated by a basic mucous membrane that protects the stomach from the digestive power of the acid and enzymes. If the stomach contents become too acidic, this basic membrane breaks down by acid-base neutralization reactions. At the point where the barrier is neutralized, the gastric juices can begin to digest the protein that makes up the stomach wall, as shown in Figure 15.14. This causes the discomfort of acid indigestion and may cause more serious problems. 

Fran s junk-food breakfast and her worrying about the exam combine to give her an annoying case of acid indigestion, which she calms by drinking some baking soda mixed with water. The baking soda contains a base that neutralizes some of her excess stomach acid. 

Milk of magnesia is an aqueous suspension of magnesium hydroxide [Mg(OH)2] used to treat acid indigestion. Calculate the volume of a 0.035 M HCl solution (a typical acid concentration in an upset stomach) needed to react with two spoonfuls (approximately 10 mL) of milk of magnesia [at 0.080 g Mg(OH)2/mL].

Simethicone, a surfactant that may decrease foaming and hence esophageal reflux, is included in many antacid preparations. However, other fixed combinations that are marketed for acid indigestion , particularly those with aspirin, are potentially unsafe in patients predisposed to gastroduodenal ulcers and should not be used. 

Aluminum hydroxide is an effective antacid because it is, chemically, a base. As such, it reacts with stomach acid (hydrochloric acid HC1), to reduce the symptoms of heartburn, upset stomach, acid indigestion, and gastritis, an inflammation of the stomach lining. The compound can also be used to treat peptic ulcers on a long-term basis. A peptic ulcer is an open sore in the lining of the stomach or the first part of the small intestine.
