This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Antacid? Wrong! If the Antacid is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Antacid then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

An
antacid is any substance, generally a base, which counteracts
gastric acid. In other words, antacids are stomach acid neutralization.
Action mechanism
Antacids perform a neutralization reaction, i.e. they
buffering agent gastric acid, raising the pH to reduce acidity in the stomach. When gastric
hydrochloric acid reaches the nerves in the gasitrointestinal mucosa, they signal Pain and nociception to the central nervous system. This happens when these nerves are exposed, as in peptic ulcers. The gastric acid may also reach ulcers in the
esophagus or the duodenum.
Other mechanisms may contribute, such as the effect of aluminum ions inhibiting smooth muscle cell contraction and delaying gastric emptying.
Indications
Antacids are taken by mouth to relieve heartburn, the major symptom of
gastroesophageal reflux disease, or acid indigestion. Treatment with antacids alone is symptomatic and only justified for minor symptoms. Peptic ulcers may require H2-receptor antagonists or
proton pump inhibitors.
The usefulness of many combinations of antacids is not clear, although the combination of magnesium and aluminum salts may prevent alteration of bowel habits.
Side effects
- Aluminum hydroxide: may lead to the formation of insoluble aluminum-phosphate-complexes, with a risk for hypophosphatemia and osteomalacia. Although aluminum has a low gastrointestinal absorption, accumulation may occur in the presence of renal insufficiency. Aluminum-containing drugs may cause obstipation.
- Magnesium hydroxide: has laxative properties. Magnesium may accumulate in patients with renal failure leading to hypermagnesemia, with cardiovascular and neurological complications. See Milk of magnesia.
- Carbonate: regular high doses may cause alkalosis, which in turn may result in altered excretion of other drugs, and kidney stones. A chemical reaction between the carbonate and hydrochloric acid may produce carbon dioxide gas. This causes gastric distension which may not be well tolerated.
- Calcium: compounds containing calcium may increase calcium output in the urine, which might be associated to renal stones. Calcium salts may cause Constipation.
- Sodium: increased intake of sodium may be deleterious for arterial hypertension, heart failure and many renal diseases.
Interactions
Altered pH or complex formation may alter the
bioavailability of other drugs, such as
tetracycline. Urinary excretion of certain drugs may also be affected.
Problems with reduced stomach acidity
Reduced stomach acidity may result in an impaired ability to Digestion and absorb certain
nutrients, such as iron and the
Vitamin B. Since the low pH of the stomach normally kills ingested bacteria, antacids increase the vulnerability to infection.
