Most commercial antacids contain two or more components. The most common combinations are varying concentrations of sodium hydroxide and aluminum hydroxide.
Some widely advertised brands, those with additional components and those containing greater concentrations of the effective ingredients, tend to cost more. There are other antacids that sacrifice efficacy in the interests of taste and acceptability. Space precludes detailed listing of all products. However, labeling is required, and armed with the above information, consumers should be able to select the product most suitable to their needs.
Most commercial antacids come with some instructions. It is important to heed the contraindications and not exceed the recommended daily dose. The need for these antacids is highly individual and regular use should only be as directed by a physician.

Antacids are useful to provide rapid relief of intermittent heartburn, particularly if brought on occasionally by foods or various activities. Antacids also seem to help many of those with bloating or functional non-ulcer dyspepsia.
By reducing gastric acidity raising the intragastric pH , antacids inactivate pepsin and relieve symptoms. Over-the-counter preparations provide only temporary symptom relief. They do not prevent recurrence of symptoms or allow an injured esophagus to heal.
They should not be taken regularly as a substitute for prescription medicines — they may be hiding a more serious condition. If needed regularly for more than two weeks, consult a physician for a diagnosis and appropriate treatment. IFFGD is a nonprofit education and research organization.

Learning Objectives Examine properties of bases. Bases Bases have properties that mostly contrast with those of acids. Aqueous solutions of bases are also electrolytes. It will balance the pH of the stomach otherwise excess amounts of HCl produced will burn the stomach wall.
Examples: Aluminium or Magnesium hydroxides are commonly used antacids. Additional Information Some amount of HCl is needed for digestion but excess amount formed due to indigestion creates problems.
The antacid can only give temporary relief to the symptoms. Get Started for Free Download App. Which method of separation is used for seperating heavier and lighter components by bowing air?

However, antacids still have a place. They are most commonly used to provide quick relief of symptoms caused by stomach acid - in particular, in people who have occasional bouts of mild dyspepsia or heartburn.
Your stomach normally produces acid to help with the digestion of food and to kill germs bacteria. This acid is corrosive so your body produces a natural mucous barrier which protects the lining of the stomach from being worn away eroded.
In some people this barrier may have broken down allowing the acid to damage the stomach, causing an ulcer. In others there may be a problem with the muscular band at the top of the stomach the sphincter that keeps the stomach tightly closed. This may allow the acid to escape and irritate the gullet oesophagus. Antacids work by counteracting neutralising the acid in your stomach. They do this because the chemicals in antacids are bases alkalis which are the opposite of acids.
A reaction between an acid and base is called neutralisation. This neutralisation makes the stomach contents less corrosive. This can help to relieve the pain associated with ulcers and the burning sensation in acid reflux.
When antacids work on stomach acid, they can produce gas which may cause wind flatulence. Simeticone helps to stop this foaming effect and may sometimes be included within antacid medications. Many of the common antacids also include alginates. Most alginates work by forming a gel which floats on top of the stomach contents. The gel acts as a protective barrier, preventing stomach acid from irritating the oesophagus.
Antacids are often taken to relieve symptoms or when symptoms are expected. Your doctor or pharmacist will advise you of the dose needed and how often you should take it.
